38. The density of aluminum is 2,700 kg/m². If transverse waves propagate at 36 m/s in a 9.2 mm diameter aluminum wire, what is the tension in the wire?

Your target variable is δf, the magnitude of the difference in frequency between the waves emitted from the sonar device and the waves received by the device after reflecting off the whale. write an expression for δf in terms of the relevant frequencies using the subscript notation introduced above.
