    Answer:

    Find answers below.

    Explanation:

    Given the following data;

    c. Power = 180 Watts

    Time = 2 hours = 60*60*2 = 7200 seconds

    To find the energy used;

    Energy = power * time

    Energy = 180 * 7200

    Energy = 1296000 Joules

    d. Power = 210 Watts

    Time = 3 hours = 60*60*3 =

    Energy = 210 * 10800

    Energy = 2268000 Joules
