You are an astronaut and you have landed on a small asteroid with radius 9081 m and a mass of 700 x10^6 kg. You want to throw a small satelite of mass 9600 kg so that it will fly around the asteroid in a circular orbit. What is the weight of the satellite? Assuming that the asteroid is not rotating, how fast do you have to throw the statellite?

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
