Why is it dangerous to turn on a light when you are in a bathtub? (1 point) why do charged particles from outer space, called cosmic rays, strike earth more frequently at the poles than at the equator? (1 point) a bar magnet is dropped toward a conducting ring lying on the floor. as the magnet falls toward the ring, does it move as a freely falling object? explain. 1 point) a magneto is used to cause the spark in a spark plug in many lawn mowers today. a magneto consists of a permanent magnet mounted on a flywheel so that it spins past a fixed coil. explain how this arrangement generates a large enough potential difference to cause the spark.

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
