Question

PLEASE HELP!!!! Two science questions!!!! 20 points and brainliest!!!
1. A cylinder is submerged in water as illustrated in the diagram. Which of the following statements is true?



The pressure at A is greater than at B.
The pressure at B is greater than at D.
The pressure at D is greater than at B.
The pressure at B is greater than at C. (Not the answer)
2. A cylinder is submerged in water as illustrated in the diagram. If the area of the top and the bottom of the cylinder is the same, which of the following statements is true?



buoyant force = (force B - force C) (Not the answer!)
buoyant force = (force D - force A)
buoyant force = (force B - force A)
buoyant force = (force C - force B)

(the picture goes with BOTH)

Answer 1

1. A cylinder is submerged in water as illustrated in the diagram. Which of the following statements is true?

The pressure at D is greater than at B. This is because D is trying to get back to the surface with an amount of pressure. B has less amount of pressure.

2. A cylinder is submerged in water as illustrated in the diagram. If the area of the top and the bottom of the cylinder is the same, which of the following statements is true?

buoyant force = (force D - force A).

Edit: If you ever notice. When you fill a sink full of water. Put a glass upside down and try forcefully to submerge it under the water it will resist. This is because of the pressure and air. The glass is less dense then water. (Also depends on the glass)

Answer 2

The submerged cylinder has pressure D has been greater than pressure B. The buoyant force has been given as force D - force A.

A. Pressure can be defined as the force that has been exerted to the system per unit volume. In the given cylinder, the pressure that has been exerted by the water at the sides of the cylinder has been lower than the buoyant force that has been exerted by the cylinder for moving up to the surface.

Thus pressure D has been greater than pressure B.

B. The buoyant force has been the pressure that has been exerted by the liquid molecules against the solid object. The buoyant force has been the force that has been the total force with respect to the force of the object and has been given as:

Buoyant force = force D - force A
