Answer:

Power is the rate at which work is done.

Step-by-step explanation:

The work done divided by total time taken is called power of an object. The SI unit of power is watts. It is denoted by W. Its expression is given by :


P=(W)/(t)

Since, W = F.d


P=(F* d)/(t)

Since,
(d)/(t)=v


P=F* v

It is also equal to the product of force and velocity. Hence, the correct option is (c).
