The primary coil of a transformer is connected to a standard wall socket. A resistance R is connected across the secondary coil. The resistance across the secondary coil is increased. What happens to the current in the primary coil, and what happens to the power being supplied by the wall socket?A) The current in the primary coil increases, and the power being supplied by the wall socket decreases
B) The current in the primary coil increases, and the power being supplied by the wall socket increases
C) The current in the primary coil decreases, and the power being supplied by the wall socket decreases
D) The current in the primary coil decreases, but the power being supplied by the wall socket remains the same
E) The current in the primary coil decreases, and the power being supplied by the wall socket increases

Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 23 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 740 n. at the top of the loop, the rider is upside down and moving, and the sensor reads 370 n. what is the speed of the rider at the top of the loop?
