A 41-m length of wire is stretched horizontally between two vertical posts. The wire carries a current of 82 A and experiences a magnetic force of 0.13 N. Find the magnitude of the earth's magnetic field at the location of the wire, assuming the field makes an angle of 61.0° with respect to the wire.

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° 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.)
