Two science 20 points and !
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)

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)

Organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
