Question

If 270 watts of power is used in 42 seconds, how much work is done? (Unit is joules (J), just type the number. Use commas if necessary).

Answer 1

Answer:

11340

Explanation:

Power = Work/time.

P = W/t ................ Equation 1

Make W the subject of the equation,

W = Pt.................. Equation 2

Given: P = 270 Watts, t = 42 seconds

Substitute these values into equation 2

W = 270(42)

W = 11340 J

Hence the work done  is 11340

Answer 2

Answer:11340 J
