Answer:
D.
Explanation:
8.1X10 to the power of 6 Joules.
Answer:
7.92×10^6Joules
Explanation:
Power is defined as the rate of change in work done. Mathematically, Power = Workdone/Time
Given power = 1.1×10³watts
Time = 2.0hours = 2×60×60
= 7,200seconds
Workdone = power × time
Work done = 1.1×10³×7200
Workdone = 7,920,000Joules
= 7.92×10^6Joules
