ONLY NEED SECOND PART

A piece of music wire with a mass of 0.46 g is used in a piano for the key of F above middle C. The wire is to be tuned to a fundamental frequency of 349 Hz. Knowing that the wire is anchored between tightening posts that are 24 cm apart, determine the tension in the wire required to produce the correct note. (T=53.7 N)

Find the temperature change needed in the room for the note frequency to drop by 2% if the music wire has a coefficient of thermal expansion of 12 x 10-6 /°C, a diameter of 1/16”, and a modulus of elasticity of 30 x 106 psi or 207 GPa
