Question

A wire is stretched by a tension of 650 n and has a mass per unit length of 0. 060 g/cm. What is the speed of the waves on this wire?

Answer 1

Mass per unit length (μ) =
= 0.06 x 10^-3/0.01
μ = 0.006
Force of tension (Ft) = 650N

v = √(Ft/μ)

= √(650 / 0.06)

= 3.29 x 10^2 m/s

Therefore, the speed of the waves is approximately 3.29 x 10^2 m/s
