A violinist plays a very fast passage in which each tone lasts only 0.25 seconds. How many to and from oscillations does the string make during this time when the frequency of the tone is 220 Hz? (A below middle C)
How many oscillations does the string make when the frequency of the tone is 660 Hz? (E above high C)?

The standard frequency of the musical pitch called “middle C” is 261.6 Hz. How fast, in meters per second, would a source emitting a tone of middle C have to move toward you so that you would hear the pitch C# (C sharp) above middle C, with a frequency of 277.2 Hz? Assume that takes place in air at a high altitude, where the speed of sound is 303 m/s please show work

Pendulum Clocks Are Very Important...
1. Pendulum clocks are very important for the history of exploration. Accurate time was the best way to determine one's longitude, since the time of sunrise or sunset depends sensitively on your longitude. In this regard, the great enemy of accuracy was thermal expansion of the pendulum used for the chronometer. We are considering a large mass attached at the end of a brass rod. The mass at the end is much greater than the mass of the rod, so we...
