ANSWER:-

#POWER-

*The rate of doing work is called as power.

*It is also defined as the rate of transfer of energy.

*Power measures the speed of work done, that is, how fast or slow a work is done.

*Power= Work/Time or P= W/T which is J/s.

*The unit of power is "Watt".

* P= W/t

=> P= F×s/t

=>P= F × v

*We express larger rates of energy transfer in kilowatts (kW).

#Applications of power in our daily life:-

* Mechanical power:- Such as cars, engines, train engines, jet planes, etc.

*Electric power- All electrical appliances such as elevator motors, electric car engines, power lines, etc.

*Power of light sources (visible and non-visible):- Household lightbulbs, x-ray machines, gamma-ray guns, radio transmitters, etc.

*Thermal power- Steam engines and turbine rotators, etc.

*Atomic power- Polaris subs, atomic electric power plants, atomic bombs.
