Answer:

The resistance of the copper wire supplying electricity to this pump is 0.005 ohm

Step-by-step explanation:

Given

Per day cost of running centrifugal pump is $30

Charge of electricity is 9.7 cents per kilowatt hour

Total electricity power consumed

\frac{30}{0.097} \\309.278 kilowatt hour

Current flowing through the pump

= \frac{309.278}{240} \\= 1.288A

Resistance of the pump

\frac{1.288}{240} \\0.005 ohm

The resistance of the copper wire supplying electricity to this pump is 0.005 ohm
