Power Practice Worksheet.docx

Solve for the change in energy using the power equation, and don’t forget to convert the given time of 2hr into seconds (2hr = 7200s). P = ΔE/t, 7W = ΔE / 7200s, solving for ΔE = (7J/s)*(7200s) = 50,400J. 7. We know that we want the student to be able to generator 50,400J of energy, and the problem says they can continuously produce 30W of ... ................
