a 0.057 kg tennis ball and a tennis racket collide. The racket has an initial momentum of -3.15 kg* m/s and a final momentum of -2.21 kg m/s. The ball has an initial momentum of 0.03135 kg m/s. If you assume the collusion is elastic, what is the final velocity of the ball

Calculate the capacitance of a system that stores 2.0 x 10^-10c of charge at 100.0 v. use c=q/v. a. 2.0 x 10^-12 f b. 2.0 x 10^-8 f c. 5.0 x 10^11 f d. 5.0 x 10^7 f

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.

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
