What is the concept called when the poles of an electromagnet were to flip?

One swimmer in a relay race has a 0.580 s lead and is swimming at a constant speed of 3.98 m/s. He has 51.3 m to swim before reaching the end of the pool. A second swimmer moves in the same direction as the leader.

Power is measured in: A) J/s B) J2/s C) s/J D) s2/J

Your car travels 600 miles in 6 hours. You stop the car for lunch for 1 hour and then you continue on your trip for another 14 miles and finish the entire trip in 8 hours. What was your car's average speed while you were driving?

Speed is a vector quantity

The observation location A is located at m. The conventional current running through the wire is 7.5 amperes. In this exercise you will calculate the magnetic field at the observation location due only to segment 4 of the wire.
