In a cyclinder a heavy piston is moving with speed v as shown diagram and gas is filled inside it. A gas molecule is moving with speed `v_(0)` towards moving piston. Then which of the following is correct (Assume `v lt lt lt lt v_(0)(Delta l)/(l)` and coillision is elastic)

If object begins to move with speed v_0 , what will be the speed of its image?

For a moving particle, which of the following options may be correct? Here, V_(av) is average velocity and v_(av) the average speed.

For a moving particle, which of the following options may be correct? Here, V_(av) is average velocity and v_(av) the average speed.

A body of mass m moving with a velocity v is acted upon by a force. Write expression for change in momentum of the following case: when v lt lt c

An ideal gas is inside a cylinder with a piston that can move freely. The walls of the cylinder and piston are non- conducting. The piston is being moved out of the cyl- inder at a constant speed u. (a) Consider a gas molecule of mass m moving with speed v (gt gt u) . It hits the piston elastically at an angle of incidence q. Calculate the loss in kinetic energy of the molecule. (b) If the area of piston is A and pressure of the gas is P, calculate the rate of decreases of molecular kinetic energy of the gas sample. (c) If u gt gt molecular velocities, at what rate will the gas lose its molecular kinetic energy

A car moves towards a hill with speed v_c .It blows a horn of frequency f which is heard by an observer following the car with speed v_0 .The speed of sound in air is v.

A particle of mass m moving with horizontal speed 6 m//s as shown in the figure. If m lt lt M then for one - dimensional elastic collision , the speed of lighter particle after collision will be
