To calculate the rate at which an object moves you subtract Position A, 5.20 m, from Position B, 102.10 m, and then divide by the time it took to move between positions, 4.81 s. Using the rules presented here, what should the final answer be?

a. 20 m/s
b. 20. m/s
c. 20.1 m/s
d. 20.15 m/s

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 answer is b. dilution
