State if each of the following statements is true or false. Give reasons for your answer. In an elastic collision of two bodies, the momentum and energy of each body is conserved.

Assertion: Frictional forces are conservative forces. Reason: Potential energy can be associated with frictional forces.

When a conservative force does positive work on a body , the potential energy of the body increases /decreases/ remains unaltered .

Assertion:- During adiabatic expansion of an ideal gas, temperature falls but entropy remains constant. Reason:- During adiabatic expansion, work is done by the gas using a part of internal energy and no heat exchange teakes place the system and the surrounding.

Assertion: In isothermal process whole of the heat energy supplied to the body is converted into internal energy. Reason: According to the first thermodynamics DeltaQ=DeltaU+PDeltaV

Assertion :- According work energy theorem net work done on a body is equal to change in its kinetic energy. Reason :- The work energy theorem is independent of Newton's second law.

Assertion: The velocity of flow of a liquid is smaller when pressure is larger and vice versa. Reason: According to Bernoulli's theorem, for the stream line flow of an ideal liquid, the total energy per unit mass remains constant.

An experiment takes 10 minutes to raise the temperature of water in a container from 0^(@)C "to" 100^(@)C and another 55 minutes to convert it totally into steam by a heater supplying heat at a uniform rate. Neglecting the specific heat of the container and taking specific heat of water to be 1 "cal//g ^(@)C , the heat of vapourization according to this experiment will come out to be:-

Statement -1 : When a girl jumps from a boat, the boat slightly moves away from the shore. and Statement-2 : The total linear momentum of an isolated system remain conserved.

A particle is to move along the x- axis from x=0 to x=x_(1) while a conservative force, directed along the x- axis, acts on the particle. For each force defination presented in the figures the maximum magnitude of the force (F_(1)) is the same for all cases. Rank the forces according to the change in potential energy associated with the motion shown. from most positive to most negative :
