The temperature of outside the orchestra.

Question

A copper wire has a radius of 200 μm and a length of 5.0 m. The wire is placed under a tension of 3000 N and the wire stretches by a small amount. The wire is plucked and a pulse travels down the wire. What is the propagation speed of the pulse? (Assume the temperature does not change:(ρ = 8.96 g/cm3, Y = 1.1 × 1011 N/m.)

You are a flutist in a local orchestra. On a cold winter day, you are late to a performance. Arriving at the orchestra hall, you know that you have missed the group tune-up before the performance, so you tune your instrument in the cold air outside the stage door. After tuning, you run inside the auditorium, where the temperature is 23.7°C, take your seat, and begin playing the first song with the rest of the orchestra. You are quite embarrassed to notice that you are playing the song a half-step higher than your colleagues in the orchestra. Your excitement about physics overcomes your musical embarrassment as you realize that you can use this information to calculate the temperature outside. (Assume that the length of the instrument does not change with temperature. A half-step represents a frequency ratio of 21/12. Enter the temperature in °C.) °C

An orchestra contains both string and wind instruments. The orchestra tunes their instruments in the morning at a temperature at Tc=15 degrees celsius. As they play, the temperature rises in the afternoon to Th= 30 degrees celsius and falls in the later evening back to Tc= 15 degrees celsius. As usual, the speed of sound in air increases with increasing temperature.
