The two highest-pitch strings on a violin are tuned to 450 Hz (the A string) and 649 Hz (the E string). Part A What is the ratio of the mass of the A string to that of the E string? Violin strings are all the same length and under essentially the same tension. Express your answer using three significant figures. MA mg IVE ΑΣΦ ?

A piano tuner stretches a steel piano wire with a tension of 765 N. The steel wire has a length of 0.500 m and a mass of 3.75 g  Part A What is the frequency f1 of the string's fundamental mode of vibration? Part B What is the number n of the highest harmonic that could be heard by a person who is capable of hearing frequencies up to f = 16 kHz?

Part A Two steel guitar strings A and B have the same length and are under the same tension. String A has a diameter of 0.65 mm and string B has a diameter 1.17 mm. Treat the stretched-out strings as right cylinders with length L and radius r having volume n L. You may assume that both strings are made of the same material, so they have the same density. The ratio of the wave speeds, VA/VB, in the two strings is (enter your answer with two significant figures) possibly useful: density = mass/volume v = Af string fixed at both ends: An = 2L/n ; n = 1, 2, 3, 4, 5... %3D V = squareroot[F/µ) H = mass per unit length 1.8 Sumit Previous Answers Correct Part B The ratio of the eleventh harmonic frequency of string A to the eleventh harmonic frequency of string B, (111)A/(f11)B, is (enter your answer with two significant figures) 1.8 Bubm Previous Answers Correct

The ability to hear a "pin drop" is the sign of sensitive hearing. Suppose a 0.53 g pin is dropped from a height of 31 cm, and that the pin emits sound for 1.4 s when it lands. Part A Assuming all of the mechanical energy of the pin is converted to sound energy, and that the sound radiates uniformly in all directions, find the maximum distance from which a person can hear the pin drop. (This is the ideal maximum distance, but atmospheric absorption and other factors will make the actual maximum distance considerably smaller.) Express your answer using two significant figures.

The G string on a guitar is 49 cm long and has a fundamental frequency of 196 Hz. A guitarist can play different notes by pushing the string against various frets, which changes the string's length. The fifth fret from the neck gives C (261.63 Hz); the sixth fret gives Db (277.18 Hz). A Part A How far apart are the fifth and sixth frets?
