Answer 2

Correction Question:

A Pump Raises Water by Spending 4 × 1$0^{5}$ J of Energy in 10 S. Find the Power of Pump.

40,000 Watts

Given:

Energy that is used by the pump to raise water

=  4 × 1$0^{5}$ Joules

Joules is the SI unit of energy

Time taken by the pump

= 10 Seconds

To Find:

The power of the pump.

Calculating:

The formula used to calculate Power is:

Power = Energy / Time

Substituting all the given values into this formula we get:

= $\frac{4.10^{5} }{10}$

Taking 10 in the denominator to the numerator:

= $4.10^{5}.10^{-1}$

Subtracting the 10^-1 from 10^5:

$= 4.10^{5 - 1}$

= 4 x 1$0^{4}$

= 40,000 Watts

Therefore, the power of the pump is 40,000 Watts.

We write the power here in Watts because the SI unit of power is Watts.
