A body is moving undirectionally under the influence of a source of constatn power. It displacement in time t is proportional to (i) `t^(1//2)` (ii) t (iii) `t^(3//2)` (iv) `t^(2)`

A body is initially at rest. It undergoes one-dimensional motion with constant acceleration. The power delivered to it at time t is proportional to (i) t^(1//2) (ii) t (iii) t^(3//2) (iv) t^(2)

A body is moved along a straight line by a machine delivering constant power . The distance moved by the body in time t is proportional to

If displacement x at time t is x = sqrt(1+ t^(2)) , then acceleration is

If displacement x at time t is x=sqrt(1+t^(2)) , then acceleration is

A body at rest is moved in a stright line by supplying constant power to it . Distance moved by the body in time t is found to be proportional to t^(n) Value of n 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
