Tudent a runs down the hallway of the school at a speed of vo=5.00m/s, carrying a ringing 1024.00-hz tuning fork toward a concrete wall. the speed of sound is v=343.00m/s. student b stands at rest at the wall. (a) what is the frequency heard by student b? (b) what is the beat frequency heard by student a?

Atelevision set that has been running for a while heats up even the air around it. which two laws of thermodynamics could be used to analyze this scenario

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?
