View answer & explanation

Correct answer

Answer: (c)C.

Fiscal deficit as percentage of GDP has been as per the Budget Estimates.

Why this answer is correct

Statement 3 is not correct.

Key Points

  • The NK Singh committee (set up in 2016) recommended that the government should target a fiscal deficit of 3% of the GDP in years up to 31st March 2020, cut it to 2.8% in 2020-21, and to 2.5% by 2023.
  • The government describes the fiscal deficit of India as the excess of total disbursements from the Consolidated Fund of India, excluding repayment of the debt, over total receipts into the Fund (excluding the debt receipts) during a financial year.
  • In simple words, it is a shortfall in a government's income compared with its spending.
  • The Fiscal Deficit for 2019-20 Provisional Actuals stood at 4.6 percent of GDP, which was 0.8 percentage points higher than the Fiscal Deficit. Hence option 3 is not correct.
  • In either case, the income figure includes only taxes and other revenues and excludes money borrowed to make up the shortfall.

Additional Information

  • The substantial deceleration in the nominal GDP growth reflects poorly on the government's fiscal marksmanship. In other words, it signifies that the government was not able to assess the magnitude of economic growth deceleration that was underway.
  • The poor fiscal marksmanship, in turn, leads to inaccurate policymaking because a government could end up making policies for an economy that does not actually exist on the ground. The fiscal policy 2019-20 was characterized by sluggish growth in Tax revenue relative to the budget estimates.
  • The Non-Tax revenue registered considerably higher growth in the first eight months of this financial year compared to the same period last year. The country's fiscal deficit widened to 4.6 percent of the Gross Domestic Product in the year 2019-20 mainly on account of poor revenue realization, according to official data. The deficit, which signifies the gap between government revenue and expenditure, is higher than the revised estimate of 3.8 percent for the fiscal.

View answer & explanation

Correct answer

Answer: (a)A.

primary goods

Why this answer is correct

The correct answer is primary goods.

Key Points

  • The new series of IIP has a total of 809 items occurring in the manufacturing sector in the item basket (405 item groups).

  • A brief table giving the use-based classification;

  • In the table, Primary goods have the highest weight of 34% and capital goods have the least weight i.e. 8.22%. Hence option 1 is correct.

  • The essence of the article is that the Index of Industrial Production (IIP) is like the thermometer of an economy. It shows the real picture of all the main sectors of the economy. If the performance of these 8 core sectors of the economy is good then the overall development of the country is inevitable.

Additional Information

  • Intermediate Goods:
  • Intermediate good is an incomplete good that goes as input for further finishing. Thus, in the production chain, Intermediate goods lie between raw material and finished goods.
  • The term Capital Goods is used for Plants, machinery, and other assets which are used for the conversion of basic goods to finished goods. We note here that Capital Good provides service without losing its essential functional characteristic, form, or shape except wear and depreciation. Further, a Capital Good itself is a finished good because it itself does not need any further processing.
  • Consumer Durable Goods:
  • Non-perishable goods such as electronics come under the category of Consumer durables. Such goods don’t need to be purchased frequently because they are made to last for long period, at least three years. They are generally of higher price in comparison to the non-durables.

    population grows

View answer & explanation

Correct answer

Answer: (a)A.

price of a commodity falls

Why this answer is correct

The correct answer is the price of a commodity falls.

Key Points

  • The demand curve is a curve that is used in microeconomics to determine the quantity of any particular commodity that people are willing to purchase with corresponding changes in its price.
  • A demand curve graph depicts the relationship between the price of a commodity (the y-axis) and the quantity of that commodity that is demanded at that price (the x-axis).
  • The demand curve will shift to left or right as a result of the change in any nonprice determinant of demand. Thus, normally there is no shift in the demand curve when the price of a commodity falls.
  • Several factors like rising income, change in population, changes in expectations and changes in tastes and preferences affect individual and market demand.

Important Points

  • Determinants of Demand:
  • There are five determinants of demands:
  • Price of the good
  • Taste or level of desire for the product by the buyer
  • The income of the buyer
  • Prices of related products:
  • Substitute products (directly competes with the good in the opinion of the buyer; e.g. tea & coffee)
  • Complementary products (used with the good in the opinion of the buyer; e.g. car & petrol)
  • Future expectations:
  • The expected income of the buyer
  • The expected price of the good.
  • Changes That Decrease Demand:
  • The following changes decrease demands:
  • The decrease in the price of a substitute
  • Increase in the price of a complement

  4. DOption (d)

    Perfect competition

View answer & explanation

Correct answer

Answer: (d)D.

Perfect competition

Why this answer is correct

The correct answer is Perfect competition.

Key Points

  • In a perfect competition market structure, there are a large number of buyers and sellers. All the sellers of the market are small sellers in competition with each other.
  • There is no one big seller with any significant influence on the market. So all the firms in such a market are price takers. Hence option 4 is correct.
  • Perfect Competition:
  • Participants are high both buyers and sellers.
  • Products have many substitutes and no marketing or selling cost is incurred.
  • Knowledge of participants for entering into the market is perfect.
  • The seller is a Price taker, not a price maker.
  • The buyer willing to buy all at a certain price but none at price higher. So he is a price maker.

Additional Information

  • Monopoly:
  • Buyers are many but the seller is one.
  • Product has no substitute or no close substitute
  • Other competitors can't enter the market due to laws or patents.
  • Price discrimination is seen between poor and rich. Seller is a Price maker.
  • Relative Price inelastic increase means demand decreases by less than X% for an X% increase in price.
  • A natural monopoly is when there is an extremely high fixed cost of distribution e.g. gas, water, electricity.
  • Monopolistic competition:
  • Many buyers and sellers but each selling its differentiated version of good.
  • Marketing selling cost is high. Goods are of different brands where brand loyalty is seen to a limit but many substitutes are available.
  • Unrestricted and free entry.
  • Seller is Price maker to a level.
  • Price increases by x% but demand decreases by less than x% - relatively inelastic. But more elastic than monopoly.
  • Oligopoly:
  • Buyers many but sellers few with intense competition.
  • Product has close substitutes and intense competition amongst sellers. If one seller introduces change others have to follow. High cost of marketing and selling.
  • Entry of new sellers tough due to economies of scale.
  • The seller is a price maker.
  • Monopsony:
  • The monopoly of the buyer but multiple sellers present.
  • Entry closed for other buyers
  • Seen where the government wants to make a defense-related purchase and multiple sellers are bidding for it.
  • The buyer is a price maker.

View answer & explanation

Correct answer

Answer: (c)C.

16th November is celebrated as the International Day for the Preservation of the Ozone Layer.

Why this answer is correct

The correct answer is 16th November is celebrated as the International Day for the Preservation of the Ozone Layer.

Key Points

  • Ozone is another important component of the atmosphere found mainly between 15 and 55 km above the earth's surface. It acts as a filter and absorbs the ultra-violet rays radiating from the sun and prevents them from reaching the surface of the earth.
  • Ozone depletion is the destruction of stratospheric ozone by free radicals like chlorine, bromine when they reach the upper atmosphere. The UV radiations break down the Chlorine molecules into Chlorine atoms. These chlorine atoms combine with Oxygen atoms broken from Ozone molecules to form ClO molecules leaving fewer amounts of Oxygen atoms to form the Ozone again. This process reduces the number of Ozone molecules in the stratosphere resulting in depletion of the Ozone layer.
  • The Dobson Unit is a way to describe how much ozone there would be in the column if it were all squeezed into a single layer. The average amount of ozone in the atmosphere is roughly 300 Dobson Units.
  • September 16th every year is marked as the International Day for the Preservation of the Ozone Layer.
  • On this day 32 years ago, 45 countries signed a treaty to phase out the use of the substances that harm or deplete the ozone layer, however, all 197 countries of the world ratified the agreement later. Hence option 3 is incorrect.

Important Points

  • Montreal Protocol on Substances that Deplete the Ozone Layer
  • The Montreal Protocol under the Vienna Convention (the protocol) was agreed to in 1987.
  • It facilitates global cooperation in reversing the rapid decline in atmospheric concentrations of ozone.
  • Under the protocol, countries agreed to phase out the production and consumption of certain chemicals that deplete ozone.
  • Phase-out of these substances are required by specific deadlines.
  • The Vienna Convention and its Montreal Protocol are the first and only global environmental treaties to achieve universal ratification, with 197 parties.
  • As a result of the international agreement, the ozone hole in Antarctica is slowly recovering.
  • Climate projections indicate that the ozone layer will return to 1980 levels between 2050 and 2070.

  • Against the arms & weapons and for Satyagraha.
  • About Ram Manohar Lohiya:
  • He was a staunch supporter of positive discrimination a state shall make to uplift the position of women, OBCs, and other vulnerable groups. This makes sense in a present-day society where reservation is being provided to the various group by the supreme law of the land under Art 16(b) (reservation to OBC, SC & ST) and by 73rd and 74th C.A.A (women in local bodies elections.).

  • He called for the eradication of caste and class-based society. At present, it is required to establish an egalitarian and inclusive society.
  • He called for planned production. To achieve the goals of SDG, and fight the twin menace of climate change and global warming, his idea needs to be implemented with true intentions.
  • He was critical of foreign domination, which is needed to maintain the sovereignty of the nation and so that its developmental benefits reach the last man of the society.

  • He also advocated politics as a practice of ethics and values, which is desirable in the present political environment.

Why this answer is correct

The correct answer is A-State to be secular must be democratic.

Key Points

  • Secularism as a Western term is defined as the separation of powers of church and State.

  • Democracy is not a prerequisite for establishing a secular state though secularism works best when adapted to a democratic system. Hence option 3 is correct.
  • Characteristics of the secular society: 
  • Separation of state & religion- Religious groups, do not interfere in affairs of state, and the state does not interfere in religious affairs.
  • Religious freedom- Defend the absolute freedom of the religious and other beliefs. It protects the rights of both the believers and non-believers.
  • Equal access to public services- No discrimination is allowed to access public services based on religion. State-funded schools are non-religious in character.
  • It refuses theocracy, Theocracy is a government by divine guidance or by the officials who are regarded as divinely guided. In several theocracies, government leaders are members of the clergy, and the state's legal system is based on religious law. Contemporary examples of theocracies include Saudi Arabia, Iran, and the Vatican.
  • Protection of free speech & expression- Religious people have the right to express their beliefs publicly but so do those who oppose/question those beliefs.

Key Points

  • Democracy comes from the Greek word, demo, and Kratos meaning people and rule. In democracies, it is the people who hold autonomous power over legislators and government.
  • Democracy is a political form of government in which governing power is derived from the people, by consensus (consensus democracy), by direct referendum, or through elected representatives of the people (representative democracy).
  • A form of political organization of society based on a recognition of the people as the source of power, their right to participate in the resolution of state affairs, and the provision of a rather broad range of rights and liberties for citizens.

Additional Information

  • Features of protective democracy:
  • Protective democracy believes in popular sovereignty. But since people cannot directly take part in the processes of state, they do it through their representatives.
  • Both the popular sovereignty and representative form of government are legitimate.
  • It is the primary duty of the state to protect the rights and liberties of citizens and whether this is properly performed or not people keep a strong vigilance over the functions of the state. Hence option 3 is correct.
  • The authority is accountable to the People and to establish it, elections are held regularly. There are also other ways of establishing accountability
  • A very important way of protecting the rights, liberties, and distribution of privileges is the division of powers among legislature, executive, and judiciary. This is done in all liberal democracies.
  • There is the prevalence of constitutionalism. Both the ruler and the ruled are controlled by the principles laid down in the constitution.
  • The constitution is the source of power for all and is the guarantor of rights and liberties. There are also measures to prevent the violation of rights and liberties.
  • Organizations associations groups have enough freedom and they always act as friends of citizens and fight against any violation of rights or encroachment on liberty.
  • Competition in all spheres is a feature of protective democracy.
  • A clear distinction between state and civil society is strictly maintained.

Important Points

  • Laissez-faire is an economic system in which transactions between private groups of people are free from or almost free from any form of economic interventionism such as regulation and subsidies.

  • Writ means written command in the name of the court.

Key Points

  • It is a legal document that is issued by a Court that orders a person or entity to perform a particular act or to stop performing a specific deed.
  • Article 32 of the Indian Constitution makes the law of issuing the writs by the supreme court and Article 226 gives the law of issuing the writs by the high court.
  • In India, only 'prerogative writs' are issued which are issued under different circumstances.
  • 'Prerogative writs' are of five kinds: writ of certiorari, writ of quo warranto, writ of habeas corpus, writ of prohibition, and writ of mandamus.

Additional Information

 Jurisdiction and powers of the Supreme Court - 

  • Original jurisdiction - Under the Original jurisdiction, the Supreme court can decide the dispute between -  
  • Any dispute between the Centre and one or more States.
  • Any dispute between the Centre and one or more States on one side and one or more States on the other side.
  • Any dispute between two or more States.
  • Writ jurisdiction - 
  • Article 32(2) of the Constitution of India provides:'' The Supreme Court shall have the power to issue directions or orders or writs, including writs in the nature of habeas corpus, mandamus, prohibition, quo warranto, and certiorari, whichever may be appropriate, for the enforcement of any of rights conferred by this Part.
  • Under article 226, an individual can move to the High Court for enforcement of the fundamental rights as well as for any other purpose also i.e. for enforcement of any other legal right.
  • It means that the writ jurisdiction of the High Court is wider than that of The Supreme Court. 
  • ​Hence statement 3 is correct.
  • Appellate Jurisdiction - It can be classified into four heads :
  • Appeals in constitutional matters
  • Appeals in civil matters
  • Appeals in criminal matters
  • Appeals in the special leave
  • Advisory jurisdiction -  Article 143 of the Indian constitution authorizes the president to seek the opinion of the Supreme court in the two categories of matters :
  • On any question of law or fact of public importance which has arisen or which is likely to arise. (In this case, the Supreme court may refuse to tender its opinion to the president).
  • Hence statement 2 is incorrect.
  • On any dispute arising out of any pre-constitution treaty, agreement, covenant, engagement, sanad, or similar instruments. (In this case, the Supreme court must tender its opinion to the president)
  • A court of record - 
  • In 1991 Supreme court has ruled that it has the power to punish for the contempt not only of itself but also of high courts, subordinate courts, and tribunals functioning in the entire country.

Important Points

  • The institution of high court originated in India in 1862 when the high courts were set up at Calcutta, Bombay, and Madras.
  • Articles 214 to 231 in Part VI of the Constitution deal with the organization, independence, jurisdiction, powers, procedures, and so on of the high courts.
  • Constitution does not specify the strength of a high court and leaves it to the discretion of the president.
  • The chief justice of the High Court is appointed by the President after consultation with the chief justice of India and the governor of the state concerned.
  • He holds office until he attains the age of 62 years.

  • The momentum of an object is equal to the product of the mass of the object and its velocity.

Key Points

  • Let us display this with p.
  • Its vector sign is in the direction of velocity.
  • Its SI unit is "kg-meter / second".
  • Suppose the mass of the body be represented by 'M' and velocity be represented by 'V'.
  • If 'p' denotes the momentum of the body.
  • p = MV
  • if momentum gets doubled, If no mass was added, the velocity must've doubled.
  • i.e. V = 2V
  • Kinetic Energy=mv22=p22m=4p22mKinetic\space Energy = \frac{mv^2}{2} = \frac{p^2}{2m} = 4\frac{p^2}{2m}, where 'p' is the linear momentum of the body.
  • Since 'p' becomes doubled, hence the kinetic energy will increase by a factor of 4.

Important Points

  • If a body is moving in a horizontal circle then its kinetic energy is the same at all points, but if it is moving in a vertical circle, then the kinetic energy is different at different points.
  • Either potential energy is a form of energy that results from an object's position or arrangement of parts. It is stored energy that can become kinetic energy.
  • The measurement of potential energy in an object is calculated based on its mass and its height or distance.
  • PE = mgh.

  • Newton's law of gravitation explains the gravitational force.

Key Points

  • Newton's law of gravitation states that the two particles in the universe are attracted to each other by a force called the gravitational force which is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them.
  • F=  G × (M1 × M2) / d2.
  • G is a gravitational constant.
  • G= 6.67 × 10-11 Newtons kg-2 m2.
  • This means that if the distance between the two objects is doubled and since the distance is inversely proportional to the gravitational force it will become 1/(2*2)= 1/ 4.
  • Also if the masses are doubled and since masses are directly proportional to the gravitational force it will become 4 times (2*2).

Additional Information

  • Gravitational Potential Energy:
  • It is the energy possessed by a body at a certain point when work is done by the force of gravity in bringing the object from infinity to that point.
  • The gravitational potential energy between two masses m1 and m2 separated by a distance d is given byU=−Gm1m2U=−Gm1m2r

EXPLANATION:

  • The gravitational potential (V) is the gravitational potential energy per unit mass.
  • At an infinite distance, the gravitational field is assumed to be zero and hence, it will not interact with the mass with regard to gravitational potential. Thus, when E = 0, V = 0.
  • We know that the gravitational field inside a spherical shell is zero. The gravitational potential inside a shell is the same as that on the shell.

  • The branch of science which studies the properties of neutrons and interaction with others is called Nuclear Physics.

Additional Information

  • Neutrons were discovered by James Chadwick in 1932 and he also got the Nobel Prize in physics for this discovery in 1935.
  • James Chadwick fired alpha radiation at a beryllium sheet from a polonium source. This led to the production of uncharged, penetrating radiation.
  • This radiation was made incident on paraffin wax, a hydrocarbon having a relatively high hydrogen content.
  • The protons ejected from the paraffin wax (when struck by the uncharged radiation) were observed with the help of an ionization chamber.
  • The range of the liberated protons was measured and the interaction between the uncharged radiation and the atoms of several gases was studied by Chadwick.
  • He concluded that the unusually penetrating radiation consisted of uncharged particles having (approximately) the same mass as a proton. These particles were later termed ‘neutrons’.

Answer: (b)B.

e/u

Why this answer is correct

The correct answer is e**/u**.

  • When a light ray travels from one medium to another the speed of the light in each medium changes.

Key Points

  • The degree to which a change in the direction of light in the two mediums is seen is called a refractive index.
  • This means it is the measure of how much the light is bending while travelling from one medium to another.
  • In its formula the refractive index is represented as ‘n’, the velocity of light in a vacuum is represented by ‘e’, and the velocity of light in a medium is ‘u'.
  • Then n= e/u.

Additional Information

  • The speed of light in vacuum c = 2.9972458 × 108 m/s ≈ 3.00 × 108 m/s. Index of refraction n=cv n = c v,

Question 93

Pearls are harvested from __________.

  1. AOption (a)

    Prawn

  2. BOption (b)

    Pila

  3. COption (c)

    Tuna

  4. DOption (d)

    Oyster

View answer & explanation

Correct answer

Answer: (d)D.

Oyster

Why this answer is correct

The correct answer is Oyster.

  • Pearl is a glittering object produced within the soft tissue of marine oysters and freshwater mussels.

Key Points

  • It is formed against the natural defence system which is an irritant such as a parasite that tries to enter their shell or damage their soft body.
  • A natural pearl begins its life inside an oyster's shell when an intruder, such as a grain of sand or a bit of floating food, slips in between one of the two shells of the oyster, a type of mollusk, and the protective layer that covers the mollusk's organs, called the mantle.
  • Cultured pearls are made in the same way. The only difference is that instead of accidental circumstances, a "pearl farmer" embeds a grain of sand into the mollusk.
  • Aragonite and conchiolin make up their cell and are slowly secreted in layers in oysters and mussels.
  • This creates a material called nacre or mother of Pearls which encompasses this irritant and protects the organism from it.
  • The more and thinner the layers in the pearl are the better it is.
  • The unique properties of a pearl depend on refraction,  reflection, and diffraction of light from its layers.

Question 94

  4. DOption (d)

    different origin and different function

View answer & explanation

Correct answer

Answer: (b)B.

different origin and common function

Why this answer is correct

The correct answer is the different origin and common functions.

  • The wings of the bird and bat are examples of analogous organs.

Key Points

  • This means that they have separate evolutionary origins but they are similar in functions.
  • Structural dissimilarities mean the wings of both of them are not inherited from a common ancestor with wings.
  • Bird wings consist of feathers extending all along the arm while the bat wings are the flap of skin stretched between the bones of arms and fingers.
  • They are superficially similar because both of them had to undergo natural selection that deduced them how to fly.
  • Convergent evolution is the result of analogies.

Additional Information

  • Homologous organs: 
  • They are defined as the organs of different animals that are having a similar structure but differ in their functions. The structure of the two different animals resemble but the functions of their organs vary.
  • Examples of homologous organs are the forelimbs of frog, man, and the flippers of the whale.
  • The structure of these animals is the same but they function in a different manner. The flippers are used for swimming, the forelimbs of frogs are used for jumping and propping, and the forelimbs of man are used for writing, eating, holding things, etc.
  • Having a similar structure shows that all these animals have a common ancestor.

  2. BOption (b)

    filtration

  3. COption (c)

    chromatography

  4. DOption (d)

    distillation

View answer & explanation

Correct answer

Answer: (a)A.

sublimation

Why this answer is correct

The correct answer is sublimation.

  • A mixture of sodium chloride (salt) and ammonium chloride can be separated by sublimation.

Key Points

  • Under this phenomenon, solid directly changes to gas or conversion of gas to solid without changing into the liquid state.
  • It is a process, however, by which compounds can be purified or mixtures separated and as such can be of value as a single step or as an integral part of a more complex analytical method.
  • It is applicable to a range of solids of inorganic or organic origin in a variety of different matrices and can be particularly useful when heat-labile materials are involved.
  • As a method of the sample, purification sublimation has been used to produce high-purity materials as analytical standards.
  • A specific and common example of sublimation used as a means of purification is the removal of water from heat-labile materials in the process known as freeze-drying.
  • As a separation technique, fractional sublimation has been used either to purify samples for analysis by removing undesirable components of the matrix or to remove the analyte from the matrix for subsequent analysis.
  • The mixture of sodium chloride and ammonium chloride is white in colour but when heated ammonium chloride can get converted into vapour and sodium chloride remains as it is thus this mixture is separated.
  • Ammonium chloride gets converted into hydrogen chloride and ammonia and thus the mixture is separated.

Additional Information

  • Filtration- Under this phenomenon, solid particles in a liquid /gaseous fluid are removed by the use of a filter medium that allows the flow of the fluid through membrane /filter paper. Solid particles will get trapped on it.
  • Chromatography- It is a process for separating the various components of a mixture. The different components of the mixture pass through the stationary phase at different speeds. Different speeds in phases cause them to separate from one another.
  • Distillation- It is a process where the conversion of a liquid into a vapour is subsequently condensed back to liquid form.

  4. DOption (d)

    Bromine and mercury

View answer & explanation

Correct answer

Answer: (d)D.

Bromine and mercury

Why this answer is correct

The correct answer is Bromine and mercury.

  • Bromine and mercury are the two elements that remain liquid at room temperature and standard pressure.

Key Points

  • Mercury has an atomic number 80 and its symbol is Hg while bromine has an atomic number 35 and its symbol is Br. Bromine is a reddish-brown liquid while mercury is a shiny silvery metal.
  • Mercury is commonly known as Quick Silver.
  • Mercury has an electronic configuration in which the bonds between its atoms are much weaker as compared to other metals so it remains liquid at room temperature.
  • Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is obtained by grinding natural cinnabar or synthetic mercuric sulfide.
  • Mercury is used in thermometers, float valves, mercury switches, mercury relays, fluorescent lamps, barometers, manometers, and sphygmomanometers.
  • A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.
  • Bromine has a boiling point just above the normal room temperature and its intermolecular forces are strong enough so that it does not vaporize.
  • Thus it also remains liquid. Bromine is a chemical element with the symbol Br and atomic number 35.
  • It is the third-lightest halogen and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour.
  • Its properties are intermediate between those of chlorine and iodine.
  • Bromine is used in many areas such as agricultural chemicals, dyestuffs, insecticides, pharmaceuticals, and chemical intermediates.
  • Some uses are being phased out for environmental reasons, but new uses continue to be found. Bromine compounds can be used as flame retardants.

    H2S

  2. BOption (b)

    AgS

  3. COption (c)

    AgSO4

  4. DOption (d)

    Ag2S

View answer & explanation

Correct answer

Answer: (d)D.

Ag2S

Why this answer is correct

The correct answer is ​Ag2S.

  • When silver articles are kept in open or direct contact with air, then a layer of silver oxide is formed on the surface of the articles.

Key Points

  • Due to the reaction of silver with the oxygen present in the atmosphere Silver oxide turns black in colour.
  • After an interval of time, it will form silver sulphide after coming in contact with oxygen and Hydrogen sulphide present in the atmospheric air.
  • The phenomenon is known as corrosion. It is called silver tarnishing, particularly for silver. The black substance obtained is known as the silver sulphide.
  • Silver sulphide is also black in colour.
  • The reaction that happens is:
  • 4Ag + O2 + 2H2S → 2Ag2S + 2H2O
  • A dense black solid is the only sulfide of silver. It is useful as a photosensitizer in photography. It constitutes the tarnish that forms over time on silverware and other silver objects.
  • The size of silver sulfide particles in deposited powders and colloidal solutions has been estimated with the use of X-ray diffraction, dynamic light scattering, transmission electron microscopy, and Brunauer–Emmett–Teller techniques.
  • The average size of silver sulfide Ag2S nanoparticles in stable colloidal solutions is equal to 10–20 nm. Special attention has been devoted to the investigation of the stability of synthesized colloidal solutions on the duration of their storage.

Question 101

Which of the following lenses will bend the light rays through the largest angle?

  1. AOption (a)

    Lens with power +2·0 D

  2. BOption (b)

    Lens with power +2·5 D

  3. COption (c)

    Lens with power -1·5 D

  4. DOption (d)

    Lens with power -2·0 D

View answer & explanation

Correct answer

Answer: (b)B.

Lens with power +2·5 D

Why this answer is correct

The correct answer is Lens with power +2·5 D.

Key Points

  • The lens with power +2.5 D will bend the light rays through the largest angle because a positive sign shows a convex lens. Hence option 2 is correct.
  • A convex lens concentrates the light rays that are incident on it, so it is called a converging lens.
  • The bending of light rays is maximal at the top and bottom of the convex lens because the top and bottom prisms have the greatest angle between the refracting surfaces.

Additional Information

  • Refraction is the bending of light (it also happens with sound, water, and other waves) as it passes from one transparent substance into another.

  • This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms, and rainbows. Even our eyes depend upon this bending of light. Without refraction, we wouldn’t be able to focus light onto our retina.

  • The amount of bending depends on two things:

  • Change in speed – if a substance causes the light to speed up or slow down more, it will refract (bend) more.

  • The angle of the incident ray – if the light is entering the substance at a greater angle, the amount of refraction will also be more noticeable. On the other hand, if the light is entering the new substance from straight on (at 90° to the surface), the light will still slow down, but it won’t change direction at all.

Important Points

  • Lenses:
  • A lens is simply a curved block of glass or plastic. There are two kinds of lenses.
  • A convex lens is thicker at the middle than it is at the edges. This is the kind of lens used for a magnifying glass. Parallel rays of light can be focused on a focal point. A biconvex lens is called a converging lens.
  • A concave lens curve is thinner at the middle than it is at the edges. Light rays refract outwards (spread apart) as they enter the lens and again as they leave.

Question 102

A luminous object is placed at a distance of 40 cm from a converging lens of a focal length of 25 cm. The image obtained in the screen is ________.

  1. AOption (a)

    erect and magnified

  2. BOption (b)

    erect and smaller

  3. COption (c)

    inverted and magnified

  4. DOption (d)

    inverted and smaller

View answer & explanation

Correct answer

Answer: (c)C.

inverted and magnified

Why this answer is correct

The correct answer is inverted and magnified.

Key Points

  • Focal length,f=25cm
  • Object distance from mirror=40cm
  • Center of curvature=2f=50cm
  • This means the object is between f and 2f
  • That's why- real, inverted, magnified and magnification, m>-1
  • Inverted Image: an image, either real or virtual, that has a vertical orientation opposite to that of the object an image that is upside-down compared to the orientation of the object. Note: The image focussed directly on the retina of the eye is an inverted image.
  • Magnified Image: A magnified image is an image that is enlarged by a mirror or lens.
  • The image will be real, inverted, and magnified. Hence option 3 is correct.

Question 103

When a light ray enters into glass medium from water at an angle of incidence 0º, what would be the angle of refraction?

  1. AOption (a)

    90∘ 

  2. BOption (b)

    45∘ 

  3. COption (c)

    0∘ 

  4. DOption (d)

    The ray will not enter at all

View answer & explanation

Correct answer

Answer: (c)C.

0∘ 

Why this answer is correct

The correct answer is 0∘ .

Key Points

  • A light ray will refract as it enters and leaves the glass, as there is a change in refractive index.
  • When a light ray travels along the normal, its speed changes in the second medium but the direction remains the same.
  • Thus when the angle of incidence is zero degrees then the angle of refraction will also be zero degrees.

 

Important Points

  • According to Snell’s law, the angle of refraction, θr, depends on the angle of incidence, θi, and the ratio of the refractive indices of the two media that make up the interface.
  • If the media have identical refractive indices, there is no refraction and the angle θr=θi.
  • Similarly, light that enters the interface normal to its surface does not deviate, because θi=0° and sin θi=0 and therefore θr=0°.

Question 104

Which one of the following phenomena verifies the fact that light travels much faster than sound?

  1. AOption (a)

    Twinkling of stars in night sky

  2. BOption (b)

    Lighting of a matchstick

  3. COption (c)

    Thunderstorm

  4. DOption (d)

    Mirage

View answer & explanation

Correct answer

Answer: (c)C.

Thunderstorm

Why this answer is correct

The correct answer is Thunderstorm.

Key Points

  • Light and sound are very different.
  • Sound is a mechanical disturbance that travels through air or another medium.
  • Sound needs a medium to travel through a medium that determines its speed.
  • A thunderstorm is a loud noise that follows a flash of lightning. Lightning can be seen before the sound of thunder is heard as light travels faster than sound. Hence option 3 is correct.
  • The speed of sound in the air is 300m/s while Light travels at 186,282 meters per second.
  • This indicates the reason why we see lightning first in a thunderstorm because the visible light waves formed by the plasma in the lightning travel to our eyes much faster than the crack of thunder sound that reaches our ears.

Additional Information

  • According to Einstein’s Special Relativity, the speed of light has a unique status: it’s a fundamental feature of our Universe, representing the maximum speed at which information can travel from place to place.
  • As such, nothing can match the 300,000km/s achieved by light travelling through a vacuum – least of all sound, which being waves of compression and expansion in a substance doesn’t even exist in a vacuum.
  • That said, light can be slowed down by being passed through transparent materials – by around 33 percent in the case of glass. Even so, it still zooms through glass around 50,000 times faster than sound waves.

Important Points

  • The twinkling of a star: is due to the atmospheric refraction of starlight.

  • The starlight, on entering the earth’s atmosphere, undergoes refraction continuously before it reaches the earth.

  • The atmospheric refraction occurs in a medium of gradually changing refractive index.

  • Since the atmosphere bends starlight towards the normal, the apparent position of the star is slightly different from its actual position.

  • When we rub a matchstick against the rough surface of a matchbox, then friction between the head of the matchstick and the rough side of the matchbox produces heat. This heat burns the chemicals present on the head of the matchstick due to which the matchstick lights up.

  • A mirage is an optical phenomenon that creates the illusion of water and results from the refraction of light through a non-uniform medium.

  • Mirages are most commonly observed on sunny days when driving down a roadway.

  • As you drive down the roadway, there appears to be a puddle of water on the road several yards (maybe one hundred yards) in front of the car. Of course, when you arrive at the perceived location of the puddle, you recognize that the puddle is not there. Instead, the puddle of water appears to be another one-hundred yards in front of you.

Question 105

Which of the following combinations of source and screen would produce the sharpest shadow of an opaque object?

  1. AOption (a)

    A point source and an opaque screen

  2. BOption (b)

    An extended source and an opaque screen

  3. COption (c)

    A point source and a transparent screen

  4. DOption (d)

    An extended source and a transparent screen

View answer & explanation

Correct answer

Answer: (a)A.

A point source and an opaque screen

Why this answer is correct

The correct answer is A point source and an opaque screen.

Key Points

  • A point light source is a single and a small one that gives off the light in all directions, such as a lit candle.
  • It is a source of light that has no screen or lampshade to block the direction in which the light can travel.
  • As light rays travel from the point source and strike an opaque object, the light rays do not travel through an opaque object.
  • There is an area behind the object where the light rays do not reach, and this is the place where the dark shadow forms.
  • If the distance between the object and the light source changes, the scattering of the light rays changes.
  • When the object is far from the point source, the light rays coming from the source do not scatter much.
  • As the object restricts the light rays being emitted at smaller angles, a smaller, sharper shadow forms behind it. Hence option 1 is correct.

Additional Information

  • Shadow is a space when the light is blocked by an opaque object. It is a part where light does not reach.
  • Shadow is formed when an opaque object is placed in the path of light.
  • For shadow formation, there should be a source of light, an opaque object, and a screen where the shadow reflects.
  • A shadow can not be formed through a transparent object likewise lens can't form shadow as the light will pass directly through it.

Correct answer

Answer: (a)A.

one X chromosome from mother and one X chromosome from father

Why this answer is correct

The correct answer is one X chromosome from the mother and one X chromosome from the father.

Key Points

  • Chromosomes are structures found in the center (nucleus) of cells that carry long pieces of DNA. DNA is the material that holds genes. It is the building block of the human body.
  • Chromosomes also contain proteins that help DNA exist in the proper form.
  • Chromosomes come in pairs.
  • Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes).
  • Half comes from the mother, the other half comes from the father.
  • Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born. They are called sex chromosomes:
  • Females have 2 X chromosomes.
  • Males have 1 X and 1 Y chromosome.
  • The mother gives an X chromosome to the child. The father may contribute an X or a Y. The chromosome from the father determines if the baby is born as male or female.
  • A human being has 23 pairs of chromosomes in which one pair of X and Y chromosomes determine the sex of the human being.
  • If there is one X chromosome from the mother and one X chromosome from the father, then two X chromosomes (XX) make a girl whereas X chromosome from mother and Y chromosome from father then these chromosomes (XY) make a boy. Hence option 1 is correct.
  • The remaining chromosomes are called autosomal chromosomes.
  • They are known as chromosome pairs 1 through 22.

View answer & explanation

Correct answer

Answer: (c)C.

tritium

Why this answer is correct

The correct answer is tritium.

  • The most stable radioactive isotope is tritium, with a half-life of 12.32 years.

Key Points

  • Hydrogen is the first element in the periodic table and has the atomic number one.
  • Those elements which have the same atomic number but a different mass number are called isotopes.
  • There are three isotopes of hydrogen namely, protium 1H1, deuterium 1H2 or D, and lastly tritium 1H3 or T.
  • The isotopes are different because of the different number of neutrons present in them.
  • In protium, there is no presence of neutrons, whereas in deuterium we have one neutron and in tritium, we have two neutrons.
  • The most prominent form of hydrogen is protium, 0.0156% of hydrogen is present on the earth’s surface as deuterium.
  • In tritium, the concentration is one atom per 1018 atoms of protium. Out of these three isotopes of hydrogen.

Important Points

  • Out of these three isotopes of hydrogen, only tritium is radioactive in nature which emits low energy b particles.
  • As the electronic configuration of isotopes is the same, they all have similar chemical properties. But they have a difference in their rates of reaction, this happens because of the different bond disassociation enthalpies.
  • They have different physical properties because of the large variations in mass.
  • The occurrence of hydrogen on earth is difficult due to its light nature.
  • In combined it forms 15.4% of hydrogen that occurs in the earth’s crust and oceans.
  • Hydrogen also occurs in plant and animal tissues, hydrocarbons, proteins, hydrides, and many other compounds.
  • In the universe, hydrogen is the most abundant element (70% of the total mass) and it is also the principal element of the solar atmosphere.

    Tin

  4. DOption (d)

    Silver

View answer & explanation

Correct answer

Answer: (d)D.

Silver

Why this answer is correct

The correct answer is Silver.

Key Points

  • The metal which is not from the first row of the d-block of the periodic table will not react with oxygen.
  • The metals which have in general low reactivity and do not react with oxygen are called noble metals.
  • Here, we are given some metals and we will need to check their reactivity with oxygen to find which one will not react with it.
  • Almost all the metals react with oxygen and form their corresponding oxides depending on their valency.
  • There is an exception that noble metals do not react with oxygen and so they do not form oxides while reacting with gaseous oxygen.
  • The noble metals are the ones that do not react with oxygen gas and do not get corroded.
  • The metals like Gold, Platinum, Silver, Ruthenium, etc are examples of noble metals. So, Silver whose chemical symbol is Ag does not react with oxygen. Hence option 4 is correct.

    3, 5

View answer & explanation

Correct answer

Answer: (d)D.

3, 5

Why this answer is correct

The correct answer is 3, 5.

Key Points

  • The atomic number of phosphorus is 15.
  • The number of electronic configuration are 2,8,5.
  • When the atom gains 3 electrons the orbit is filled. or otherwise the atoms should lose 5 electrons. the valency is the combining capacity of the atom. therefore the valency of phosphorus is 3 and 5. Hence option 4 is correct.

Additional Information

  • We know that the atomic number of phosphorus is 15 and its electronic configuration in the ground state is [Ne] 3s23p3.
  • We know that phosphorus also has a vacant 3d-orbital. In an excited state, electrons are excited from a lower energy level to a higher energy level. Here in phosphorus in an excited state, an electron is excited from 3s to 3d orbit. Now, the electronic configuration of phosphorus in the excited state is 

[Ne]3s13p33d1.

  • In the electronic configuration of the excited state of phosphorus, we can see that there are five unpaired electrons in it.
  • The valency of an atom is its tendency to make bonds with other atoms.
  • Here, the exciting state phosphorus has five unpaired electrons means it can form five bonds with some other atoms.
  • Then the valency of phosphorus in the excited state is 5.
