Which of these best describes how the kinetic energy of carbon dioxide molecules change as the carbon dioxide is heated? (2 points) kinetic energy decreases. kinetic energy increases. kinetic energy increases, then decreases. kinetic energy decreases, then increases.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
