Question

A power P is required to do work W in a time interval T. What power is required to do work 3W in a time interval 5T? (a) 3P (b) 5P (c) 3P/5 (a) P (e) 5P/3

Answer 1

(c) 3P/5

Step-by-step explanation:

The formula to calculate the power is:

`P=(W)/(T)`

where

W is the work done

T is the time required for the work to be done

In the second part of the problem, we have

Work done: 3W

Time interval: 5T

So the power required is

`P=(3W)/(5T)=(3)/(5)(W)/(T)=(3)/(5)P`
