Question

A steel wire 0.72 m long has a mass of 5 x 10⁻³ kg. If the wire is under a tension of 60N, what is the speed of the transverse waves on the wire?

Answer 1

93m/s

Step-by-step explanation:

Solution,

Here,

Length(l)=0.72m

Mass(m)=5x 10⁻³

T=60N

As we have

v=√T/μ

And

μ=m/l

μ=5 x 10⁻³ /0.72

Now

v=√60×0.72/5 x 10⁻³

v=√8640

v=92.95m/s=93m/s
