Answer published by the source. Consult the official source to check your work against its answer.
question
An electrical transmission line is strung across a valley between two utility towers. The distance between the towers is 200 m, and the mass of the line is 40 kg. A lineman on one tower strikes the line and a wave travels to the other tower, is reflected, and is detected by the lineman when it returns. If the elapsed time measured by the lineman is 10 s, what is the tension force in the wire?
