Alternating current is generated by a rotating generator which moves in such a way as to produce that kind of current.
Convection currents move in upward direction
The wind can stir up ocean currents, particularly surface currents, increasing their speed and changing their direction. This can lead to a phenomenon known as wind-driven circulation, where the movement of water is influenced by the force and direction of the wind.
An oceans currents will change direction when they hit a continent.
Ocean currents reverse in the winter compared to the summer because of changes in temperature and wind patterns. During the summer, warmer water and prevailing winds create specific currents, whereas in the winter, colder temperatures and changing wind directions lead to a reversal in the flow of currents.
No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
The surface currents move in a clockwise direction in the Northern hemisphere, and move in a counter clockwise direction in the Southern hemisphere! Hope it helped:)
oppositional currents
In the Northern Hemisphere, ocean currents generally move in a clockwise direction, while in the Southern Hemisphere, they move in an anti-clockwise direction. This is due to the Coriolis effect, which is caused by the Earth's rotation and influences the direction of moving objects.
Alternating Current
You can control sound wave direction, by changing the direction and pressure of air.
When cars are changing direction, they are also changing their velocity vector, which includes speed and direction. This change in velocity requires acceleration, which can be in the form of turning left or right, slowing down, or speeding up.
The opposite of changing directions would be maintaining a course, or continuing in the same direction.
