Answer:
7200 secs
Explanation:
Power is the rate at which work is done. Mathematically, it is represented as:
Power (P) = Energy (E) /Time (t)
P = E/t
Power is measured in Watt (W).
Energy is measured in Joule (J).
Time is measured in seconds (s).
In calculating for the power, we must expresed the energy in joules and the time in seconds.
For the question given above, we must convert 2 hours to seconds before calculating the power.
To convert from hours to seconds, we simply do the following:
1 hr = 3600 secs
Therefore,
2 hrs = 2 x 3600 = 7200 secs
Therefore, the value for the time, t will be 7200 secs.
