16.3 Exercise 9

Avg difficulty 2.5

A copper wire has a density of ρ=8920kg/m3,\rho = 8920 \text{kg}/\text{m}^{3} , a radius of 1.20 mm, and a length L. The wire is held under a tension of 10.00 N. Transverse waves are sent down the wire. (a) What is the linear mass density of the wire? (b) What is the speed of the waves through the wire?
