when an object is submerged in water, the buoyant force

is equal to the weight of the fluid displaced

Explanation:

This principle is useful for determining the volume and density of an object by measuring its mass in air and it's mass in water. The name of that rising force acting on objects submerged in water is a buoyant force.

Buoyancy power is equal to the weight of displaced water. The buoyant force does not depend on the total depth of the submerged object. Sometimes the buoyant force increases as the object go deeper and deeper into the fluid. But the bouyon force does not depend on depth. It just depends on the volume of fluid displaced, the density of the water and the acceleration.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
