Astudent blows up a balloon and then places it in a very cold freezer. after a few hours, the balloon has shrunk. which of the following best explains why the balloon shrunk? a. as the balloon gets cooler, the molecules gain energy and move closer together, causing the balloon to shrink. b. as the balloon gets cooler, the molecules lose energy and move closer together causing the balloon to shrink. c. as the balloon gets cooler, the molecules break apart, decreasing the volume of the gas. d. as the balloon absorbs energy, the molecules move more quickly, making the balloon expand.

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
