A metal rod is connected to a battery through two stiff metal wires that hold the rod horizontally. The rod is between the poles of a horseshoe magnet that is sitting on a mass-measuring platform scale, which reads 100 g. After you turned on the current in the circuit, the scale supporting the magnet read 106 g. The rod is 7.0 cm long and the current through it is 1.1 A. Find the magnitude of the magnetic field. B =

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0Β° north of east. the plane then flies to town b, located d2 = 230 km at 30.0Β° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)
