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?

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
