Question

How much power does a toaster have if it does 1,000 joules of work in 30 seconds?

Answer 1

33.33Watts

Step-by-step explanation:

Given parameters:

Work done = 1000J

Time taken = 30s

Unknown:

Power = ?

Solution:

To solve this problem, we must understand that power is the rate at which work is done.

So;

Power =
`(Work done )/(time)`

Now insert the parameters:

Power =
`(1000)/(30)` = 33.33Watts
