General Awareness PYQs

The correct answer is Antarctica.

Key Points

• The ozone hole was first discovered in 1985 by a team of scientists from the British Antarctic Survey (BAS), comprising Joseph Farman, Brian Gardiner, and Jonathan Shanklin.
• Their groundbreaking research was published in the scientific journal Nature, showing a dramatic seasonal decline in ozone levels over the Antarctic continent.
• The discovery was based on long-term data collected at the Halley Research Station and the Faraday Research Station using Dobson spectrophotometers.
• The thinning of the ozone layer was found to be most severe during the Southern Hemisphere spring (September to November) due to the presence of the Polar Vortex.
• The researchers observed that total ozone values had dropped by nearly 40 percent compared to measurements taken in the late 1950s and 1960s.

 Additional Information

• Ozone Layer and Mechanism:
• The ozone layer (O₃) is situated in the Stratosphere, roughly 15 to 35 kilometers above Earth, and absorbs harmful Ultraviolet (UV-B) radiation.
• The destruction of ozone is catalyzed by Chlorine and Bromine atoms released from Chlorofluorocarbons (CFCs) and Halons.
• In Antarctica, extreme cold leads to Polar Stratospheric Clouds (PSCs), which provide the chemical surface for CFCs to convert into active chlorine that destroys ozone.
• Comparison with Arctic:
• While ozone depletion also occurs in the Arctic, it is typically less severe because Arctic temperatures are warmer and the polar vortex is less stable than in Antarctica.
• Montreal Protocol:
• Following the discovery in Antarctica, the international community signed the Montreal Protocol in 1987 to phase out Ozone-Depleting Substances (ODS) globally.

The correct answer is Punjab.

Key Points

• Giddha is a popular and energetic folk dance that originated in the Punjab region, encompassing parts of modern-day India and Pakistan.
• It is traditionally performed by women and is often referred to as the feminine counterpart to the Bhangra dance, which is traditionally performed by men.
• The dance is characterized by its high-spirited rhythm, where performers stand in a circle and take turns performing in the center while others provide a rhythmic accompaniment through clapping.
• A defining feature of Giddha is the singing of Boliyan, which are traditional folk couplets or short songs that narrate stories of household life, social issues, family relationships, and female emotions.
• It is most vibrantly performed during the Teeyan festival to welcome the monsoon, as well as during the Baisakhi harvest festival and weddings.
• The attire for Giddha typically involves bright-colored Salwar Kameez or Lehenga paired with traditional Punjabi jewelry like the Saggi Phul and heavy embroidery work.

 Additional Information

• In the Ramayana, it is believed that Lord Rama and Goddess Sita offered prayers to the Sun God upon returning to Ayodhya.

The correct answer is They conducted yajnas and chanted mantras in low tones.

Key Points

• The Adhvaryu (or Adhvarya) was one of the four primary types of priests essential for the performance of Vedic rituals and sacrifices during the Vedic Period.
• According to the Yajurveda, which is the 'Veda of Prose Mantras' or 'Book of Rituals', the Adhvaryu was responsible for the physical and manual execution of the Yajna (sacrifice).
• The specific duties of the Adhvaryu included measuring the sacrificial ground, constructing the Vedi (altar), preparing the sacrificial vessels, lighting the sacred fire, and offering the Havis (oblation).
• During the ritual process, the Adhvaryu recited the Yajus (sacrificial formulas) in a specific rhythmic, low-toned chant, which is a characteristic feature that distinguished them from the high-pitched recitation of the Hotri.
• The role of the Adhvaryu ensured the precision of the ritual's technical steps, acting as the 'chief executive' of the sacrificial ceremony to maintain the sanctity and efficacy of the Vedic sacrifice.

 Additional Information

• The Vedic Priesthood consisted of four main categories, each associated with one of the four Vedas:
• Hotri:
• Associated with the Rigveda.
• Responsible for invoking the deities and reciting the Rig (hymns) during the sacrifice.
• Udgatri:
• Associated with the Samaveda.
• Specialized in singing the Saman (melodies), often compared to the musical aspect of the rituals.
• Brahman:
• Associated with the Atharvaveda.
• Served as the silent observer and supervisor of the entire Yajna to ensure no mistakes were made and to provide Prayaschitta (expiation) if errors occurred.
• The Yajurveda itself is divided into two major versions: the Shukla Yajurveda (White) and the Krishna Yajurveda (Black), containing the collections of prayers and sacrificial formulas used by the Adhvaryu.

The correct answer is 0.009 rad.

Key Points

• Angular diameter (or angular size) is the angle subtended by a circular object as seen by an observer from a specific distance.
• For celestial objects where the distance is significantly larger than the actual diameter, we utilize the small-angle approximation formula: θ ≈ D / d.
• In this formula, D represents the Moon's diameter, which is 3,474 km, and d represents the average distance from Earth, which is 384,000 km.
• The calculation is set up as θ = 3,474 ÷ 384,000, which yields the result in radians.
• Performing the division gives θ = 0.009046875 radians.
• Rounding to three decimal places, the angular diameter of the Moon as seen from Earth is 0.009 rad.

 Additional Information

• Small-Angle Approximation:
• This principle is used in astronomy and physics when the angle is small enough that the angle itself (in radians) is approximately equal to its sine and tangent.
• Radian Measure:
• A radian is the standard unit of angular measure. To convert radians to degrees, multiply by 180/π. An angle of 0.009 rad is roughly 0.51 degrees.
• Orbital Variations:
• The Moon follows an elliptical orbit. At perigee (closest point), its angular diameter appears slightly larger, while at apogee (farthest point), it appears smaller.
• Visual Appearance:
• The Sun has an angular diameter also measuring about 0.5 degrees. Because the Sun and Moon have similar angular sizes, total solar eclipses are possible when their paths align.

The correct answer is It increases.

Key Points

• According to Kepler's Third Law of Planetary Motion (the Law of Harmonies), the square of the orbital period (T) of a satellite is directly proportional to the cube of its orbital radius (r), expressed as T² ∝ r³.
• The orbital radius (r) is defined as the distance from the center of the Earth to the satellite, which is the sum of the Earth's radius (R) and the satellite's altitude (h), mathematically shown as r = R + h.
• When the altitude of the satellite increases from 300 km to 500 km (an increase of 200 km), the total orbital radius (r) also increases.
• The relationship for the orbital period is derived from the formula \( T = 2\pi \sqrt{\frac{r^{3}}{GM}} \); since the radius (r) is in the numerator, an increase in altitude directly results in a longer orbital period.

 Additional Information

• Orbital Velocity and Altitude:
• The orbital speed (v) of a satellite is inversely proportional to the square root of the orbital radius, given by \( v = \sqrt{\frac{GM}{r}} \).
• As the satellite's altitude increases, its orbital speed decreases; at an altitude of 300 km, the speed is approximately 7.8 km/s, but this speed will drop as it moves to 500 km.
• A slower speed combined with a longer orbital path (greater circumference) results in a significantly higher time period for one complete revolution.
• Low Earth Orbit (LEO) Characteristics:
• Satellites at altitudes between 160 km and 2,000 km are considered to be in Low Earth Orbit.
• The average Earth radius used in these orbital calculations is approximately 6,371 km.
• The Universal Gravitational Constant (G) is 6.674 × 10⁻¹¹ Nm²/kg² and the Mass of Earth (M) is roughly 5.97 × 10²⁴ kg.

The correct answer is 1.1 times.

Key Points

• The concept of efficiency (η) in propulsion and mechanical systems defines the ratio of the useful energy output (ideal energy) to the total energy input (actual energy).
• The mathematical relationship is expressed as η = Ideal Energy ÷ Actual Energy. To find the actual energy used relative to the ideal energy, the formula is rearranged as Actual Energy = Ideal Energy ÷ η.
• The problem specifies an efficiency of 90%, which corresponds to a decimal value of 0.9.
• To determine the factor of actual energy used, we calculate the ratio 1 ÷ 0.9, which equals approximately 1.111.... Hence, the actual energy used is 1.1 times the ideal energy when rounded to one decimal place.
• The payload capacity of 4000 kg and the specific satellite mass of 3600 kg indicate that the rocket is operating within its structural limits, but the energy ratio remains dependent on the system efficiency.

 Additional Information

• GSLV Mk III (LVM3):
• Commonly known as the Launch Vehicle Mark 3 (LVM3), it is the most powerful rocket developed by the Indian Space Research Organisation (ISRO).
• It is designed to deliver heavy communication satellites into Geosynchronous Transfer Orbit (GTO) using a complex cryogenic upper stage (C25).
• The vehicle utilizes two S200 solid strap-on boosters and an L110 liquid-propellant core stage to achieve the necessary thrust-to-weight ratio for heavy lifting.
• The specific impulse (Isp) and combustion efficiency of its engines determine the overall propellant mass required to reach a specific orbital velocity, where lower efficiency necessitates a higher mass fraction of fuel.

The correct answer is It does not react easily..

Key Points

• Nitrogen exists as a diatomic molecule (N₂) and is characterized by its high chemical stability and lack of reactivity under standard atmospheric conditions.
• The primary reason for its inertness is the presence of a very strong triple covalent bond between the two nitrogen atoms, which requires a significant amount of energy to break.
• The bond dissociation energy of the nitrogen-nitrogen triple bond is approximately 941.4 kJ/mol, which is considerably higher than the bond energies of oxygen or hydrogen.
• Because of this extreme bond strength, nitrogen does not readily participate in chemical reactions at room temperature, acting as a diluent that slows down the combustion process of oxygen in the atmosphere.

 Additional Information

• Atmospheric Composition:
• Nitrogen is the most abundant gas in the Earth's atmosphere, comprising roughly 78% of the total volume.
• Despite being inert, it is a vital component of amino acids, proteins, and DNA in all living organisms.
• Nitrogen Fixation:
• The strong triple bond can only be broken by high-energy processes such as lightning strikes or through biological nitrogen fixation by specific bacteria like Rhizobium.
• Industrially, the Haber-Bosch process uses high pressure and temperature with a catalyst to overcome this inertness to produce ammonia.
• Industrial Applications:
• Nitrogen is used to provide an inert atmosphere in food packaging to prevent oxidation and spoilage.
• It is utilized in cryogenics as liquid nitrogen for the preservation of biological samples due to its low boiling point of −195.8°C.

The correct answer is Perpendicular to field lines.

Key Points

• A rectangular loop carrying a current behaves as a magnetic dipole. It possesses a magnetic dipole moment (m), which is a vector quantity defined by the product of the current (I) and the area (A) of the loop (m = I × A).
• The direction of the magnetic moment is always perpendicular to the plane of the loop, as determined by the right-hand thumb rule.
• When suspended in a magnetic field (B), the loop experiences a torque (τ) that tends to rotate it. This torque is expressed by the formula: Torque = m × B sin(θ), where θ is the angle between the magnetic moment and the field lines.
• A system is in stable equilibrium when its potential energy (U) is at a minimum. The potential energy for a magnetic dipole is given by U = −mB cos(θ).
• Minimum potential energy occurs when cos(θ) = 1, which means θ = 0°. In this state, the magnetic moment vector is parallel to the external magnetic field lines.
• Since the magnetic moment vector is perpendicular to the plane of the loop, for the moment to align parallel to the field lines, the plane of the loop must naturally settle into a position perpendicular to the field lines.

 Additional Information

• Parallel to field lines:
• In this orientation, the plane of the loop is parallel to the field lines, meaning the magnetic moment is perpendicular to the field (θ = 90°).
• At this position, the torque is maximum (Torque = m × B), causing the loop to rotate away from this state immediately.
• This configuration is utilized in moving coil galvanometers with radial magnetic fields to ensure constant maximum sensitivity, but it is not the natural resting position in a uniform field.
• Magnetic Flux:
• The loop naturally attains a position that maximizes the magnetic flux passing through it.
• Magnetic Flux (Φ) = BA cos(θ) is maximized when the plane is perpendicular to the field lines (θ = 0° for the area vector).
