Nata [24]

Answer:t

Explanation:

Given that,

Power output is

P = 0.50kW = 0.5 × 1000 = 500W.

We want to find energy transfer in

t = 2minutes = 2 × 60 = 120 seconds

Also, time to hour

t = 2/60 = 1/30 hour

Power is the rate of energy.

Therefore,

Power = energy / time taken

Energy = power × time taken

Energy = 0.5kW × 1/30 hr

Energy = 0.01667 kWh

Also, energy in Joule

Energy = power × time

Energy = 500W × 120s

Energy = 60,000J

Energy = 60kJ.
