355488 Assertion :
Power of machine gun is determined by both, the number of bullets fired per second and kinetic energy of bullets.
Reason :
Power of any machine is defined as work done (by it) per unit time.

355489 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

355490 A motor of power \(p_{0}\) is used to deliver water at certain rate through a given horizontal pipe. To increase the rate of water through the same pipe \(n\) times, the power of the motor is increased to \(p_{1}\). The ratio of \(p_{1}\) to \(p_{0}\) is

355491 A particle of mass \(m\) is driven by a machine that delivers a constant power \(K\) watts. If the particle starts from the rest the velocity of the particle at time \('t'\) is

355492 A motorcycle of mass \(m\) resting on a frictionless road moves under the influence of a constant force \(F\). The work done by this force in moving the motorcycle is given by \(F^{2} t^{2} / 2 m\), where \(\mathrm{t}\) is the time in seconds.
Ratio of instantaneous power to average power of the motorcycle in \(t = T\) second is:
