Answer:

The speed of waves on this wire is 329.14 m/s

Step-by-step explanation:

Given;

tension of the wire, T = 650 N

mass per unit length, μ = 0.06 g /cm = 0.006 kg/m

(convert the unit of mass per length in g/cm to kg/m by dividing by 10 = 0.06 / 10 = 0.006 kg/m)

The speed of waves on this wire is given as;


v = \sqrt{(T)/(\mu) } \\\\v = \sqrt{(650)/(0.006) }\\\\v = 329.14 \ m/s

Therefore, the speed of waves on this wire is 329.14 m/s
