A student is doing an experiment to determine the speed of sound. The experiment consists of a large tube filled with water with a smaller tube inside of it. The smaller tube can be lifted to change the distance from the open end of the tube to the water. The student holds a tuning fork that rings with a frequency of 368 Hz above the smaller tube. The small tube is raised until it is heard to resonate. The distance from the open end of the small tube to the water is 23.3 cm.
a. According to the student’s experiment, what is the speed of sound?
b. The student uses the temperature in the room to calculate that the accepted value of the speed of sound is 341.8 m/s. What will be the length from the open end of the tube to the water for the first three harmonics that are heard? Your answer should be three heights.

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?
