The density of aluminum is 2700 kg/m 3. If transverse waves propagate at 26 m/s  in a 4.6mm diameter  aluminum wire, what is the tension on the wire?

A copper wire, whose cross-sectional area is 8.58 x 106 m², has a linear density of 6.18 x 103 kg/m and is strung between two walls. At the ambient temperature, a transverse wave travels with a speed of 60.8 m/s on this wire. The coefficient of linear expansion for copper is 17 x 10-6 (Cº)-1, and Young's modulus for copper is 1.1 x 10¹1 N/m². What will be the speed of the wave when the temperature is lowered by 26.5 Cº? Ignore any change in the linear density caused by the change in temperature. Number i Units

A phone cord is 4.89 m long. The cord has a mass of 0.212 kg. A transverse wave pulse is produced by plucking one end of the taut cord. That pulse makes four round trips (down and back) along the cord in 0.666 s. What is the tension in the cord? Hint: Four round trips is a total distance of eight lengths of the cord.

The density of aluminum is 2700 kg/m3. If transverse waves propagate at 34 in a 4 mm diameter  aluminum wire, what is the tension on the wire in Newtons? Give your numerical answer as a whole number please.
