A 1430 kg race car is driving around a circular track of radius r = 102 m. In the instant shown in the figure, the vehicle has
a forward speed of v = 36.3 m/s and is slowing at a rate of
4.30 m/s2. What is the magnitude of the net force, Fnet, acting
on the vehicle at this time and the angle, e, between the net
force vector and the direction of motion?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
