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

Answer:

The speed  is $v =122.2 \ m/s$

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

           $v = \sqrt{\frac{T}{\mu} }$

substituting values

         $v = \sqrt{\frac{3.0 *10^{4}}{2.01} }$

        $v =122.2 \ m/s$
