Question

Freddie plays his Xbox for an hour. It transfers 7200 joules of energy in that time. What is the power of the Xbox?

Answer 1

P = 2 Watts

Step-by-step explanation:

Given that,

Energy transferred, E = 7200 J

Time, t = 1 hour = 3600 s

We need to find the power of the box. Power is equal to energy transferred per unit time.

`P=(E)/(t)`

Substituting the values,

`P=(7200\ J)/(3600\ s)\\\\P=2\ W`

So, the power of the box is 2 W.
