How frequent is a sound wave produced by the source (how frequent do you snap your fingers)? Is the frequency of waves emitted by the source constant, or does it change as the source moves? In other words, does the way you snap your fingers get faster, slower, or is it constant as the source moves along the screen?

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:

the objects have the same charge is correct.
