# A pump raises water by spending 4×105 J of energy in 10 s. Find the power of pump. - Physics

Sum

A pump raises water by spending 4×105J of energy in 10s. Find the power of the pump.

#### Solution

Energy spent = w = 4 × 105J

Time taken = 10s

Power = Energy / Time

P = (4 × 10^5)/10 = 4×104

Concept: Power
