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?
