Question

A 2.1W iPod is used for 30 minutes. How much energy does it use? (3

Answer 1

it us 200 energy if it the right awnser

Answer 2

Energy used, E = 3780 Joules

Step-by-step explanation:

It is given that,

Power, P = 2.1 W

Time, t = 30 minutes = 1800 seconds

We need to find the energy used by the iPod. The product of power and time is called energy used i.e.

E = P × t

`E=2.1\ W* 1800\ s`

E = 3780 Joules.

So, the energy used by the iPod is 3780 Joules. Hence, this is the required solution.
