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. (2 points) as the balloon gets cooler, the molecules gain energy and move closer together, causing the balloon to shrink. as the balloon gets cooler, the molecules lose energy and move closer together causing the balloon to shrink. as the balloon gets cooler, the molecules break apart, decreasing the volume of the gas. as the balloon absorbs energy, the molecules move more quickly, making the balloon expand.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
