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.)

When an object is heated it contracts. a. true b. false

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.
