He maximum strength of the earth's magnetic field is about 6.9 x 10-5 t near the south magnetic pole. suppose we want to utilize this field with a rotating coil to generate 87.2-hz ac electricity. what is the minimum number of turns (area per turn = 0.013 m2) that the coil must have to produce an rms voltage of 120 v?

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap

Explain why electric current cannot exist if a current doesn't have a voltage source.
