Answer:

Power = 2.5 [W]

Step-by-step explanation:

To be able to solve this problem we must remember that power is defined as the relationship of the work done in a given time interval.

P=W/t

where:

P = power [W] (units of watts)

W = work = 50 [J]

t = time = 20 [s]

Now replacing:

$P=50/20\\P=2.5[W]$
