    Answer:

    Power = 130 watt

    Explanation:

    Power is described as the ability to do work, it is also defined as the amount of work in Joules done in a given time in seconds. Mathematically, it is represented as:

    power = \frac{work (J)}{Time (s)}

    In this example, power is calculated as follows:

    Work = 39000 J

    Time = 5 minutes

    converting the time from minutes to seconds:

    1 minute = 60 seconds

    ∴ 5 minutes = 60 × 5 = 300 seconds

    \therefore power = \frac{39000}{300} \\power = 130 watt

    N:B the unit for power can also be represented as Joules/seconds or J/s or JS⁻¹
