A circular space station of radius 100 m rotates twice each minute.
a. Find the acceleration of an astronaut standing at the outer edge of the space
station. How many g's does she feel? (1g=9.8ms2)
b. What must the period of rotation of the space station be in order for astronauts
at the outer edge to experience the same acceleration as on earth?

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
