The diagram below represents the same pendulum in four different positions. Position 1
Position 2
Position 3
Position 4
At which position does the ball have the most potential energy?
O 1
O 2
O 3
04

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:

b. examine and describe cells

since electrons are negative the answer is neagtaive
