How long does it take a transverse wave to travel the entire length of the two wires?

A 36.5 m steel wire and a 13.4 m copper wire, both with 1.31 mm diameter, are connected end to end and stretched to a tension of 215 N. How long does it take a transverse wave to travel the entire length of the two wires? Answer in units of s.How long does it take a transverse wave to travel the entire length of the two wires?v=(T/m)^0.5

T--%26gt; Tension

m--%26gt; Linear Density

p --%26gt; density

m=p/cross sectional area=p/(pi)r^2 for each of the wires (u can look up their corresponding densities in any ref table)

You then plug in the value of m that you just computed into the orginal formula along with the tension to find the velocity
