Question

What is the minimum amount of wire required to supply electricity from the house to the pond if the distance is 29 m?

a) 29 m
b) 58 m
c) 87 m
d) 116 m

Answer 1

The correct answer is 58 meters since you need enough wire for it to reach the pond and return, completing the circuit.

Step-by-step explanation:

The minimum amount of wire required to supply electricity from the house to the pond if the distance is 29 meters would be twice the distance since the wire needs to both reach the pond and return to the house to complete the circuit. Therefore, the correct answer is 58 meters.

To explain further, electricity requires a complete circuit to function. A circuit begins at the source of power, extends to an appliance or fixture needing power (like a pump at the pond), and then returns to the source. If the distance is 29 meters one way, you need to double the distance to make the round trip back to the source, totaling 58 meters.
