Question

A pump raises water by spending $4 \times 10^{5}$ J of energy in 10 s. Find the power of pump.

Open in App

Solution

Energy spent = w = 4 × 10⁵ J Time
taken = 10 s
Power = Energy / Time
$P equals fraction numerator 4 cross times 10 to the power of 5 over denominator 10 end fraction equals 4 cross times 10 to the power of 4 W$
