Question

A string of mass 2.5 kg is under a tension of 200N. The length of the
stretched string is 20 m. Calculate the speed of transverse wave in the
stretched string​

Answer 1

Answer:

Explanation:

M = 2.50 kg

T = 200 N

l = 20.0 m

Mass per unit length, μ=M/l=2.50/20=0.125Kg m^−1

The velocity (v) of the transverse wave in the string is given by the relation:

v=

Ц

Time taken by the disturbance to reach the other end,

t = l/v=20/40=0.5s

​=  

= $\sqrt{1600}$  

​=40 m/s
