The left side of the armature in an electric motor is pushed down. When the current changes direction, how is the motion of the armature affected? It is pulled up on the left side. It is pulled up on the right side. It is pulled toward the commutator. It is pushed away from the commutator.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
