Sally takes two bar magnets and randomly tapes one end of each bar magnet. she labels the magnets a and b. she brings the taped ends of two magnets together and they attract each other. sally knows that opposite poles of magnets attract. she then brings the taped end of a third magnet (magnet c) near each of the first two magnets. predict her observations.

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
