Question

the following diagram shown the experiment of pressure exerted on an object we what will you conclude from this experiment​

Answer 1

Answer:

Fill roughly one-third of a cup with water. Then, cover the mouth of the cup completely with a flat, hard cardboard. Using your hand to keep it in place, turn the cup upside down. When you remove your hand, the the cardboard stays in place.

Fill roughly one-third of a cup with water. Then, cover the mouth of the cup completely with a flat, hard cardboard. Using your hand to keep it in place, turn the cup upside down. When you remove your hand, the the cardboard stays in place.One would expect that due to gravity, the water will fall, and even the cardboard will. However, it does not, which means that something must be applying an upward force on the cardboard. This is nothing other than air pressure, which applies a force across the surface of the cardboard in an upward direction.

However, it does not, which means that something must be applying an upward force on the cardboard. This is nothing other than air pressure, which applies a force across the surface of the cardboard in an upward direction. Thus we can demonstrate that air exerts pressure, because otherwise, the water would have fallen.

Answer 2

The image illustrates what happens when pressure and force are placed on board.

• A kind of push or pull is known as force.
• It is something whose action generates motion in an object. or, it can also be defined as the interaction between two objects.
• The force exerted away from the body is a push. And a pull is a force exerted towards the body.
• Force acting on a unit area is known as pressure.
• It can be seen that pressure is the ratio of the force to the area over which the force is acting.
• For a given force, pressure is higher when the area is small and lower when the area is large.
