In 1999, quantum interference was observed in a beam of so-called buckyballs: carbon molecules with the formula c60 and the shape of a soccer ball.
a) the wavelength observed was about 3 pm. how fast were the molecules moving?
b) what would be the wavelength of an electron moving at the same speed?
c) numerically justify the neglect of relativistic effects in this problem.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
