SUMMARY
The wave speed in a brass wire can be calculated using the formula v = √(T/μ), where T is the tension and μ is the mass per unit length. For a brass wire with a radius of 4.65×10-4 m and a tension of 128 N, the mass per unit length μ is determined by multiplying the density of brass (8.60×103 kg/m3) by the cross-sectional area of the wire. The cross-sectional area is calculated as A = πr2, leading to a complete solution for wave speed.
