Question

A box was lifted using a pulley. If 1,000 W were required, which of these correctly describes power and energy for this action?

500 J of energy were converted into some other energy every second and two times the power was required.
1,000 W of power were converted into 1 J of energy in one second.
1,000 J of energy were converted into some other energy each second, requiring 1,000 watts of power.
1,000 J of power were converted into some other power every second, requiring 1,000 watts of energy.
is it the third one?
