A22.0-m steel wire and a 54.0-m copper wire are attached end to end and stretched to a tension of 145 n. both wires have a radius of 0.450 mm, and the densities are 7.86 × 103 kg/m3 for the steel and 8.92 × 103 kg/m3 for the copper. (note that these are mass densities, mass per unit volume, not linear mass densities, mass per unit length.)part ahow long does a wave take to travel from one end to the other end of the combination wire? express your answer with the appropriate units.
