A2.1w ipod is used for 30 minutes. how much energy does it use? (3

Energy used, E = 3780 Joules

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 = 3780 Joules.

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

its a 5.5 n
