A 30.0 m steel wire and a 22.0 m copper wire, both with 1.00 mm diameters, are connected end to end and stretched to a tension of 170 N. How long does it take a transverse wave to travel the entire length of the two wires? (Take the mass per unit length of the wires to be 7.006 g/m for copper and 6.173 g/m for steel.)
answer in seconds.
Vsteel= sqrt(170/ (6.173/30))
Vcopper+Vsteel= incorrect answer
any help would be appreciated!
