Pascal's law is the working principle of:
सही उत्तर: घ) Hydraulic press
Pascal's law states that pressure applied to an enclosed liquid is transmitted equally in all directions, which a hydraulic press uses to multiply force. A barometer measures atmospheric pressure.

The weight of a body is maximum at:
सही उत्तर: ग) The poles
g is greatest at the poles because the Earth's radius is smallest there, so weight is maximum. At the centre of the Earth, g and therefore weight become zero.

The universal gravitational constant G has the value approximately:
सही उत्तर: ख) 6.67 × 10⁻¹¹ N m²/kg²
G ≈ 6.67 × 10⁻¹¹ N m²/kg² and is the same everywhere in the universe. 9.8 m/s² is g, the acceleration due to gravity, which varies from place to place.

The mass of a body on the Moon compared with its mass on the Earth is:
सही उत्तर: क) The same
Mass is the quantity of matter and does not change with location. Weight, not mass, becomes about one-sixth on the Moon.

-
The value of acceleration due to gravity on the Moon is about what fraction of that on the Earth?
सही उत्तर: घ) One-sixth
Because of its smaller mass and radius, the Moon's surface gravity is about 1/6 of Earth's (about 1.6 m/s²). This is why objects weigh about one-sixth as much on the Moon.

The energy possessed by a body due to its motion is called:
सही उत्तर: ग) Kinetic energy
Kinetic energy equals ½mv² and depends on speed. Potential energy is due to position or configuration.

-
The product of mass and velocity of a body is called:
सही उत्तर: ख) Momentum
Momentum p = mv and its SI unit is kg m/s. Impulse is the change in momentum (force × time).

-
Newton's first law of motion is also known as the law of:
सही उत्तर: क) Inertia
The first law says a body stays at rest or in uniform motion unless an external force acts, which describes inertia. Action and reaction is Newton's third law.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
The rate of change of velocity is called:
सही उत्तर: घ) Acceleration
Acceleration = change in velocity / time taken, measured in m/s². Momentum is the product of mass and velocity.
💬 टिप्पणी / गल्ती रिपोर्ट (०)
-
Which of the following is a vector quantity?
सही उत्तर: ख) Velocity
Velocity has both magnitude and direction, so it is a vector. Speed has magnitude only, so it is a scalar.
