Aquestion for the physicists out there:
during a thunderstorm, the potential difference between the thunderclouds and the ground builds up to v. in each stroke of lightning, 30c of charge passes between the thunderclouds and the ground. lightning strokes to the ground occur, on average, and 2 minute intervals.
calculate:
i) the average current between the thunderclouds and the ground,
ii) the energy transferred in each stroke of lightning.
i already know the answer, i'm just seeing who here is good at physics ; )

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?
