A student performs a lab measuring the velocities of toy cars of different masses. A 3 column table with 5 rows. Column 1 is labeled Car with entries Car 1, Car 2, Car 3, Car 4, Car 5. Column 2 is labeled Mass in kilograms with entries 5, 5. 5, 6, 2006. 5, 7. Column 3 is labeled Velocity in meters per second with entries 2. 2, 2, 2001. 35, 1. 90, 1. 35. Which cars have the same magnitude of momentum? Check all that apply. Car 1 car 2 car 3 car 4 car 5.

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.
