What would happen to an object if there were no inertia? also would this mean that if there were no inertia that an object may travel high speeds depending on the object's mass?

How are calculation for velocity and speed different

Hydrogen and helium are both members of?

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.
