SUMMARY
The tension in an aluminum wire with a radius of 0.001 m and a wave speed of 120 m/s can be calculated using the formula v = √(F_u/μ), where F_u is the tension and μ is the linear mass density. The density of aluminum is given as 2.7 x 103 kg/m3. To find the linear mass density (μ), the mass of the wire must be determined using its density and cross-sectional area.
