Respuesta :

Answer: 0.42 watts

Explanation:

Given that:

power = ?

energy =500 joules

time = 1200 seconds

Recall that power is the rate of energy expended per unit time

i.e Power = energy / time

Power = 500J / 1200seconds

Power = 0.416 watts (rounded to the nearest hundredth as 0.42 watts)

Thus, the power of the instrument is 0.42 watts
