355458 A force \({\vec{F}=(3 \hat{i}+4 \hat{j}) N}\) acts on a \(2\,kg\) movable object that moves from an initial position \({\vec{d}_{i}=(-3 \hat{i}-2 \hat{j}) m}\) to a final position \({\vec{d}_{f}=(5 \hat{i}+4 \hat{j}) m}\) in \({6 s}\). The average power delivered by the force during this interval is

355459 Assertion :
Kilowatt hour is the unit of power.
Reason :
One kilowatt hour is equivalent to \(1 \times 10^{4} \mathrm{~J}\).

355460 An athlete of mass 60 \(kg\) skips at the rate of 20 steps per minute through an average height of 25 \(cm\). The power developed is:

355461 \(1000\;N\) force is required to lift a hook and \({\rm{10000 }}N\) force is requires to lift a load slowly. Find power required to lift hook with load with speed \(v = 0.5\,m{s^{ - 1}}.\)

355462 An electric pump is used to fill an overhead tank of capacity \(9\;{m^3}\) kept at a height of 10 \(m\) above the ground. If the pump takes 5 minutes to fill the tank by consuming 10 \(kW\) power the efficiency of the pump should be (Take \(g = 10\,m{s^{ - 2}}\) )
