Two masses, each having a value of M, are vibrating vertically on a spring with a Hooke's law constant, k. At the lowest point of the vibration, one of the masses falls off, so that now the total mass is M instead of 2M. Comparing the new vibrational motion to the original vibrational motion: 1) How is the period of vibration different, if at all? Explain you reasoning. 2) How is the maximum acceleration different, if at all? Explain your reasoning. 3) How is the maximum velocity different, if at all? Explain your reasoning. Quantitative comparisons are preferred: i. e., one-third as large or twice as fast.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
