This may help you pls mark me as brainliest

Explanation:

Power can be expressed as the rate at which a work is done. In other words, it is the amount of energy that is transferred for one unit of time. This can be expressed in the form of an equation as:

                                                              Power = Work/Time

In the given problem, work = 20 joules (J), time = 5 seconds (s).

Thus, Power = 20 J/5 s

=> Power = 4 J/s.
