At a certain place, earth's magnetic field has magnitude b =0.703 gauss and is inclined downward at an angle of 75.4° to the horizontal. a flat horizontal circular coil of wire with a radius of 10.0 cm has 1300 turns and a total resistance of 99.4 ω. it is connected to a meter with 202 ω resistance. the coil is flipped through a half-revolution about a diameter, so that it is again horizontal. how much charge flows in coulombs through the meter during the flip?

What produces light and all other electromagnetic waves? a) the photoelectric phenomena b) heated metals c) charged particles d) radioactive samples (pls explain if you can : )

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?
