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
