Question

a crane convert 1000oule of energy in one second if it can do any work in one minute calculate the work done​

Answer 1

A 1000J or 1kJ of energy in 1 second implies that in 1 minute there will be 60kJ of energy converted.

Work is the defined as energy consumed thought time.

$W=\dfrac{E}{t}$

In our case,

$W=\dfrac{60\mathrm{kJ}}{60\mathrm{s}}=1\cdot10^3\dfrac{\mathrm{J}}{\mathrm{s}}=\boxed{10^3\mathrm{W}}$

Hope this helps!
