Question

A 100-m long transmission cable is suspended between two towers. If the mass density is 2.01 kg/m and the tension in the cable is 3.00 x 104 N, what is the speed of transverse waves on the cable

Answer 1

The speed is
`v =122.2 \ m/s`

Step-by-step explanation:

From the question we are told that

The length of the wire is
`L = 100 \ m`

The mass density is
`\mu = 2.01 \ kg/m`

The tension is
`T = 3.00 *10^(4) \ N`

Generally the speed of the transverse cable is mathematically represented as

`v = \sqrt{(T)/(\mu) }`

substituting values

`v = \sqrt{(3.0 *10^(4))/(2.01) }`

`v =122.2 \ m/s`
