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:

[tex]power = \frac{work (J)}{Time (s)}[/tex]

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

[tex]\therefore power = \frac{39000}{300} \\power = 130 watt[/tex]

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