Assertion (A): Generally the path of a projectile from the earth is parabolic but it is elliptical for projectiles going to a very large height.
Reason (R): The path of a projectile is independent of the gravitational force of earth.
Assertion: The time period of revolution of a satellite close to surface of earth is smaller than that revolving away from surface of earth.
Reason: The square of time period of revolution of a satellite is directly proportional to cube of its orbital radius.
Assertion (A): A planet moves faster, when it is closer to the sun in its orbit and vice versa.
Reason (R): Orbital velocity in orbital of planet is constant.
Assertion: In an isochoric process, work done by the gas is zero.
Reason: In a process, if initial volume is equal to the final volume, work done by the gas is zero.
Assertion: If two bodies are in thermal equilibrium in one frame, they will be in thermal equilibrium in all frames.
Reason: The transfer of energy from a hot body to a cold body is a non mechanical process, i.e., the energy is transferred from one body to the other, without any mechanical work.
Assertion: An artificial satellite is moving in a circular orbit of the earth. If the gravitational pull suddenly disappears, then it moves with the same speed tangential to the original orbit.
Reason: The orbital speed of a satellite decreases with the increase in radius of the orbit.
Asseertion: Thermodynamics processes in nature are irreversible.
Reason: Dissipative effects cannot be eliminated.
Assertion: Moon travellers tie heavy weight at their back before landing on moon.
Reason: The value of g is small at moon.
Assertion (A): A force act upon the earth revolving in a circular orbit about the sun. Hence work should be done on the earth.
Reason (R): The necessary centripetal force for the circular motion of the earth, comes from the gravitational force between earth and the sun.
Assertion (A): In projectile motion, the vertical velocity of the particle is continuously decreased during its ascending motion.
Reason (R): In projectile motion near earth surface, downward constant acceleration is present in vertical direction.
