A piano wire of linear mass density 0.0050 kg/m is under a tension of 1350 N.What is the wave speed in this wire?
A)130 m/s
B)260 m/s
C)520 m/s
D)1040 m/s

Question

Quizplus · Accepted Answer

The wave speed in a string is given by the equation:

v = sqrt(T/μ),

where T is the tension in the string, and μ is the linear mass density.

Substituting the given values, we get:

v = sqrt(1350 N / 0.0050 kg/m)

v = 520 m/s

Therefore, the best choice is C) 520 m/s.
