The correct answer is Newton.

• Newton is the SI unit of force.

Key Points

• Force:
• Force is that external cause which when acts on a body, changes or tries to change the initial state of the body.
• Force = mass × acceleration
• Its S.I. unit is Newton (kg. ms^-2).
• Force is a vector quantity.
• Dyne is the CGS unit of force.

Additional Information

• Pressure is defined as a force acting normally on the unit area on the surface.
• SI unit of pressure is N/m² also called Pascal (Pa).
• Pressure is a scalar quantity.

The correct answer is 2.

CALCULATION:​

Given - Initial velocity (U) = 10 m/s, Final velocity (V) = 20 m/s and time (t) = 5 sec

• Acceleration can be calculated by using equations of motion

⇒V = U + at

$\Rightarrow a=\frac{V-U}{t}=\frac{20-10}{5}=\frac{10}{5}=2, m/s^2$

The correct answer is Mass.

Key Points

• The law of gravitation, introduced by Sir Isaac Newton, explains the force of attraction between two objects is directly proportional to the product of their masses.
• This fundamental principle indicates that every object in the universe attracts every other object with a force that is dependent on its mass.
• The greater the mass of the objects, the stronger the gravitational pull between them.

Additional Information

• Density: Refers to the mass per unit volume of a substance but doesn't directly influence the gravitational force according to the law of gravitation.
• Volume: Is the quantity of three-dimensional space enclosed by a closed surface, and like density, it doesn’t directly factor into the law of gravitation, which is mainly concerned with mass.
• Velocity: Refers to the speed of something in a given direction. While velocity can affect the orbits of objects under gravity, the law of gravitation itself is solely about mass and the distance between masses, not their velocity.

The correct answer is Liquid.

Key Points

• Liquids take the shape of the container they are kept in, a property due to their fluidity.
• Unlike solids, liquids have no fixed shape but a fixed volume that doesn’t change with the shape of its container.
• This characteristic allows liquids to flow and conform to the contours of any container.

Additional Information

• Solid: Retains a fixed shape and volume, not taking the shape of its container. Solids have particles that are closely packed in a rigid structure.
• Gas: Has neither a fixed shape nor a fixed volume. Gases expand to fill any container they are in, diffusing to fill the entire space available.
• None of these: This option is not applicable as it is clear that liquids are substances that take the shape of the container they are kept in.

Explanation:

Nichrome:

• Nichrome has low resistivity.
• Nichrome is a non-magnetic alloy that is made up of mainly chromium and nickel.
• It has a very high melting point, which makes it nichrome to make high-temperature wires.
• It is used in heating elements such as hair dryers, toasters, and ovens.
• Nichrome is used to make the coils used in water heaters.

Tungsten:

• Tungsten is a transition metal.
• Its atomic number is 74 with the sign 'W' as Tungsten or wolfram
• The melting point of this element is very high but get oxidised at high temperature.
• So, to protect this element from getting oxidised it is kept in a container filled with inert gases

Additional Information

Electric bulb: It is an electric device that converts electric energy into heat and light energy.

• it is generally made of glass with inert gases filled in it (Nitrogen and argon).
• The filament is made of tungsten which has a very high melting point.

An alloy is a substance made by melting two or more elements together, at least one of the metals.

Calculation:

x/4 = 6/8

x = (6 × 4)/8

x = 24/8

x = 3

∴ The correct answer is Option 2).

Given

(x) × 1/4 = 6

Formula Used:

To find x, we need to isolate x on one side of the equation.

Calculation:

⇒ (x) × 1/4 = 6

To solve for x, we multiply both sides by the reciprocal of 1/4, which is 4.

⇒ x = 6 × 4

⇒ x = 24

Therefore, the value of x is 24.

Given:

Total Balls (green + red) = 160

Percentage of Green Balls = 40%

Formula Used:

Number of Green Balls = (Percentage of Green Balls / 100) × Total Balls

Calculation:

Number of Green Balls = (40/100) × 160

⇒ Number of Green Balls = 0.4 × 160

⇒ Number of Green Balls = 64

To find the number of red balls, we subtract the number of green balls from the total number of balls.

Number of Red Balls = Total Balls - Number of Green Balls

⇒ Number of Red Balls = 160 - 64

⇒ Number of Red Balls = 96

Therefore, there are 96 red balls in the bag.

Given:

Length (l) = 15 cm

Breadth (b) = 9 cm

Formula Used:

Area of Rectangle = l × b

Calculation:

⇒ Area = 15 cm × 9 cm

⇒ Area = 135 cm²

Therefore, the area of the rectangle is 135 cm²

Given:

Numbers: 24 and 36

Concept:

To find the largest number that divides both 24 and 36 exactly, we need to find their greatest common divisor (GCD).

Calculation:

List the factors of each number:

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36

The common factors are: 1, 2, 3, 4, 6, 12

The greatest common divisor (GCD) is the largest common factor: 12

Therefore, the largest number that divides both 24 and 36 exactly is 12.

Given:

$(\frac{x}{4})$ = $( \frac{6}{8})$

Concept used:

Cross-multiply or simplify the fraction on the right side:

Calculation:

$(\frac{x}{4})$ = $( \frac{6}{8})$

⇒ 8 ×  x = 4 × 6

⇒ 8x = 24

⇒ x = 24/8 = 3

So, the value of x is 3.

Given:

Average of 20 numbers = 8

Average of the first 10 numbers = 10

Concept:

Total sum of numbers = Average × Number of items.

Calculation:

Total sum of 20 numbers = 20 × 8 = 160

Total sum of the first 10 numbers

⇒ (10 × 10 = 100)

Subtract to find the sum of the last 10 numbers

⇒ (160 - 100 = 60)

Average of the last 10 numbers

⇒ (60 / 10 = 6)

Hence, the average of the last 10 numbers is 6.

Given:

The largest two-digit number is 99.

To find: By what number will 99 be divisibly among the given options.

9, 11

Check divisibility by 9 ⇒ (99 ÷ 9 = 11), divisible.

Check divisibility by 11 ⇒ (99 ÷ 11 = 9), divisible.

Result ⇒ Divisible by both 9 and 11.

5, 7

Check divisibility by 5 ⇒ 99 is not divisible because it doesn't end in 0 or 5.

Check divisibility by 7 ⇒ 99 is not divisible by 7 evenly.

Result ⇒ Not divisible by both 5 and 7.

7, 8

Check divisibility by 7 ⇒ 99 is not divisible by 7 evenly.

Check divisibility by 8 ⇒ 99 is not divisible by 8.

Result ⇒ Not divisible by both 7 and 8.

5, 6

Check divisibility by 5 ⇒ 99 is not divisible because it doesn't end in 0 or 5.

Check divisibility by 6 ⇒ For a number to be divisible by 6, it must be divisible by both 2 and 3. 99 is divisible by 3 but not by 2.

Result ⇒ Not divisible by both 5 and 6.

Therefore, only option 1) 9, 11 is correct where the largest two-digit number, 99, is divisible by both 9 and 11.

Given:

Simple Interest (SI) = ₹650

Principal (P) = ₹1300

Time (T) = 10 years

Formula Used:

Simple Interest (SI) = $\frac{P \times R \times T}{100}$

Where R is the rate of interest per annum.

Calculation:

650 = $\frac{1300 \times R \times 10}{100}$

650 = $\frac{13000 \times R}{100}$

650 = 130 × R

R = $\frac{650}{130}$

R = 5

The rate of simple interest is 5% per annum.

Given:

The first four odd prime numbers: 3, 5, 7, 11

Concept:

Average = Sum of numbers / Quantity of numbers

Calculation:

Sum = 3 + 5 + 7 + 11 = 26

Quantity = 4

Average = 26 / 4 = 6.5

Hence, the average of the first four odd prime numbers is 6.5

The logic followed here is:

Hence, the correct answer is "option (1)".

Murali is 14th from the right end in a row of 40 boys.

His position from the left end = (40 - 14) + 1

= 27.

Hence, Murali will be "27th" from the left end.

The logic used is →

Code = Sum of the positional values of each alphabet

1. All the best

⇒ 1 + 12 + 12 + 20 + 8 + 5 + 2 + 5 + 19 + 20 = 104

2. Best of luck

⇒ 2 + 5 + 19 + 20 + 15 + 6 + 12 + 21 + 3 + 11 = 114

∴ The correct answer is Option 01.

According to the sequence in the dictionary:

3. Discuss 2. Disease 5. Disgrace 1. Dish 4. Disjoin

Hence, the correct answer is "3, 2, 5, 1, 4".
