If the force acting on a body is inversely proportional to its speed, then its kinetic energy is

If the force acting on a body is inversely proportional to its speed, the kinetic energy of the body is

If the kinetic energy of a body is directly proportional to time t, the magnitude of the force acting on the body is

A uniform force of 4 N acts on a body of mass 10 kg for a distance of 2.0 m . The kinetic energy acquired by the body is

A body starts from rest and acquires velocity V in time T . The instantaneous power delivered to the body in time 't' proportional to

A variable force F acts on a body which is free to move. The displacement of the body is proportional to t^(3) , where t = time. The power delivered by F to the body will be proportional to

The force of gravity is proportional to the masses of the bodies. Then why doesn't a heavy body fall faster than a light body?

The thermal radiation emitted by a body is proportional to T^(n) where T is its absolute temperature. The value of n is exactly 4 for

Kinetic energy of a particle moving in a straight line is proportional to the time t. The magnitude of the force acting on the particle is :

A block of mass m at rest is acted upon by a force F for a time t. The kinetic energy of block after time t is
