Choose the best description of Buoyant Force.
It is an unbalance force that acts upward the vessel to keep it afloat. It must be slightly greater than the force of gravity to prevent the vessel from sinking.
It is equal to the weight of the volume submerged part of an object.
The amount of water displaced by an immersed object has a weight equal to the buoyant force.
The buoyant force is a force due to the fluid's density, volume and static pressure
No appropriate definition is given.
The best description of Buoyant Force is:
It is equal to the weight of the volume submerged part of an object.
The best description of Buoyant Force is: "It is an unbalanced force that acts upward on a vessel to keep it afloat. It must be slightly greater than the force of gravity to prevent the vessel from sinking."
To understand how to arrive at this answer, let's break down the other options:
Option 2: "It is equal to the weight of the volume submerged part of an object."
This statement is incorrect. The weight of the volume submerged part of an object is the weight of the fluid displaced, not the buoyant force itself.
Option 3: "The amount of water displaced by an immersed object has a weight equal to the buoyant force."
This statement is a bit misleading. While it is true that the weight of the fluid displaced is equal to the buoyant force, this option doesn't clearly explain that the buoyant force acts upward and keeps the object afloat.
Option 4: "The buoyant force is a force due to the fluid's density, volume, and static pressure."
This option is somewhat true, but it lacks clarity. The buoyant force is indeed determined by the fluid's density, volume, and static pressure, but it doesn't explain that the force acts upward and keeps objects afloat.
Therefore, the best description is the one given in the first option.
The best description of Buoyant Force is:
It is equal to the weight of the volume submerged part of an object.
