For this case we have that by definition, physical power refers to the amount of work done for a unit of time.
So:
[tex]P = \frac {W} {t}[/tex]
Where:
W: It's the work
t: It's time
The power units are in [tex]\frac {Joules} {s} = Watts[/tex]
So, according to the problem data we have:
[tex]P = 100W\\t = 120s[/tex]
Clearing the work of the formula:
[tex]W = P * t\\W = 100 * 120 = 1200[/tex]
Thus, the work is 1200 joules.
Answer:
Option C
