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/m3 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 10-9kg/m2-s.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?
