Answer 2

♥️ Answer :-

a. Power is the rate of doing work or the rate of utilizing energy. The power of an agent may vary with time.

The SI unit of Power is Watt.

1 watt is the power of an agent, which does work at the rate of 1 joule per second.

b.Power = Work/Time

Work done= Energy consumed by the lamp = 1000 JTime = 10s

Power= 1000/10= 100 Js-1=100 W
