In the design of a dam, the thickness of the wall is the same as the pressure of water remains the same.
In the design of a dam, the wall at the bottom of the dam is thicker as the pressure of water increases with depth.
In the design of a dam, the wall at the bottom of the dam is thinner as the pressure of water decreases with depth.
In the design of a dam, the wall at the middle of the dam is thicker as the pressure of water is highest in the middle.
The speed of the air moving at the upper surface of the air foil is less than the speed of the air moving at the lower surface of the air foil.
The speed of the air moving at the upper surface of the air foil is more than the speed of the air moving at the lower surface of the air foil.
The speed of the air moving at the upper surface of the air foil is the same as the speed of the air moving at the lower surface of the air foil.
There is not sufficient information to make a conclusion.
The air foil is moving downwards with increasing speed.
The air foil is moving upwards at a constant speed.
The air foil is moving upwards with decreasing speed.
The air foil is moving upwards with increasing speed.
