Need help in these 2 questions: 1) Two identical strings on different cellos are tuned to the 440 hertz A note. The peg holding one of the strings slips, so its tension is decreased by 1.8%. What is the beat frequency heard when the strings are then played together? 2) A steel piano wire is 84.0 cm long and has a mass of 3.10 g. If the tension of the wire is 600 N, what is the second harmonic frequency?
