Two students, nora and allison, are both the same age when allison hops aboard a flying saucer and blasts off to achieve a cruising speed of 0.830c for a 29.5 year-round trip (according to allison). neglecting the brief time periods required for the acceleration of the ship during blastoff and turnarounds, find the difference in age between nora and allison when they are reunited.

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?

The field between two charged parallel plates is kept constant. if the two plates are brought closer together, the potential difference between the two plates either a) decrease b) does not change c) increase?
