Final answer:
To find the weight of 141 meters of a uniform wire, we can use the given information. First, convert the weight of 60 meters of wire to its equivalent mass. Then, multiply this mass by the length of 141 meters to find the weight of the longer wire.
Explanation:
To find the weight of 141 meters of the uniform wire, we can use the given information. First, we convert the weight of 60 meters of wire to its equivalent mass by dividing it by the acceleration due to gravity. We then multiply this mass by the length of 141 meters to find the weight of the longer wire.
Given:
Weight of 60 meters of wire = 80 kg
Equivalent mass = 80 kg ÷ 9.8 m/s² = 8.16 kg
Length of wire = 141 meters
Weight of 141 meters of wire = Equivalent mass × Length of wire = 8.16 kg × 141 meters = 1150.56 kg
