What happens to the energy of the ball from when t = 0 s to when t = 5 s? A. Potential energy decreases and kinetic energy increases, but the total amount of mechanical energy remains the same. B. Potential energy increases and kinetic energy decreases, but the total amount of mechanical energy remains the same. C. Potential energy and kinetic energy both increase, and the total amount of mechanical energy increases. D. Potential energy and kinetic energy both decrease, and the total amount of mechanical energy decreases.

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?

Gabby calls her cousin who lives in a different state and tells her to turn her radio to channel 98.7 so they can listen to their favorite song that is playing. her cousin turns her radio to 98.7, but does not hear the same song gabby hears. which most likely explains why?

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.
