Question

You do 300 j of work in 15 s.how much power do you use?

Answer 1

Given data:

* The amount of work done is W = 300 J.

* The time during which the work is done is t = 15 s.

Solution:

The power used in terms of the work done and time taken is,

`P=(W)/(t)`

Substituting the known values,

`\begin{gathered} P=(300)/(15) \\ P=20\text{ watts} \end{gathered}`

Thus, the power used in the given case is 20 watts.
