SUMMARY
The discussion focuses on calculating the mass M attached to a suspended wire based on its second-harmonic frequency. Initially, the frequency is 200 Hz with mass M, and it increases to 245 Hz when an additional 1 kg is added. The relevant equations include the frequency formula f = v/L and the wave speed v = √(T/u), where T is the tension and u is the linear mass density. The solution involves manipulating these equations to isolate and calculate the mass M accurately.
