When candle wax is heated enough, it becomes a liquid and flows. However, if it isn't heated, candle wax is a solid. Which of the following explains why liquid candle wax flows but solid wax does not? ○ the molecules of the Liquid wax are softer than the molecules of the solid matte wax.

○ The molecules of the liquid wax have less mass than the molecules of the solid wax.

○ The molecules of the liquid wax can easily move past one another but the molecules of the solid wax cannot.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
