Mike drove 70 km due west and then 100 km due east. what is his total distance traveled? what is his total displacement? if mike took 3 hr to complete the trip, what was his average speed? what was his average velocity over the 3 hr trip?

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.
