Answer:
P = 2 Watts
Explanation:
Given that,
Energy transferred, E = 7200 J
Time, t = 1 hour = 3600 s
We need to find the power of the box. Power is equal to energy transferred per unit time.
[tex]P=\dfrac{E}{t}[/tex]
Substituting the values,
[tex]P=\dfrac{7200\ J}{3600\ s}\\\\P=2\ W[/tex]
So, the power of the box is 2 W.
