Gravity. Water will always take the path of least resistance, which is sideways. And if there is pressure from the top, Pascal's principle is in affect which states that when pressure is applied to the top of a body of water the resulting affect is pressure on all other sides of the body of water.
The direction in which water spins can be influenced by various factors such as the shape of the container, the initial motion of the water, and external forces such as wind or currents. In nature, water can exhibit different spinning directions depending on the circumstances.
yes it rotates on an axis and 'always' in the same direction.
Yes. f=ma the direction of acceleration is the direction of the force and vice versa.
Shape, rotation-direction, and orbit-direction.
no
yes
Yes it does no matter what.
Always replace inner and outer wheel bearings on the same wheel at the same. You don't necessarily have to replace the bearings in both wheels at the same time, though it's not a bad idea, but always inner and outer on the same wheel at the same time.
Same direction as the engine.
No, the acceleration of an object is in the direction of the net force applied to it. If the net force is in the same direction as the object's motion, the acceleration will be in the same direction. If the net force is opposite to the object's motion, the acceleration will be in the opposite direction.
No, they can NEVER act in the same directions.
Direct current (DC) is the name of the electric current that always flows in the same direction. It is commonly used in electronics and power transmission systems.
