Solution

The power of an appliance can be calculated using the formula:

Power (P) = Energy transferred (E) / Time taken (t)

Given in the question, Energy transferred (E) = 1000 J Time taken (t) = 45 s

Substitute these values into the formula:

P = 1000 J / 45 s = 22.22 W

So, the power of the appliance is 22.22 Watts (to 2 decimal places).
