The correct answer is <span>outboard. This is the most basic type of engine seen everywhere that is attached to regular boats so that you can move them with an engine instead of by rowing. The engine contains all that it needs in the single box and it just gets attached to the boat.</span>
The object is at rest.
This is due to the fact hwen two forces act upon each other on opposite sides, the movement of the object does not change due to the net force equaling 0.
A
Answer:
Speed of water in the 0.5cm diameter will be faster because it has a smaller area
Since area x radius ² so if radius is reduced by 0.5 speed is increased by 4times in the 0.5 diameter pipe
