- Ann is building a two string guitar for a physics project. She has 2 m of jewelers wire. She puts this on a balance and notes that the mass is 3.2 g. To make the guitar, one string will be 30 cm long and the other 45 cm long.(a) The tension of the 45 cm string is double the tension in the 30 cm string. If the fundamental frequency of the shorter string is 540 Hz, what is the fundamental frequency of the longer string? (b) Calculate the tension in the 30 cm wire.A steel wire in a piano has a length of 0.780 m and a mass of 4.60 grams.
