Part a - calculate the value of q what is the value of q when the solution contains 2.00×10−3 m ca2+ and 3.00×10−2m so42−? express your answer numerically.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

d.) circle motion requires a force to give it a centripetal acceleration.
