A student sets up the pendulum system shown below. He holds the pendulum at the top of its arc. Draw the path of the pendulum after the student releases it. Label the following points in the pendulum's path if the total mechanical energy of the
system is 100 J.

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

What problem would a person have if the nucleic acid in one of his or her cells were damaged?
