a. _____ Gives the magnitude of the buoyant force

To determine

To pick the right word from list: Gives the magnitude of buoyant force.

Answer to Problem AM

Archimedes’  principle gives the magnitude of buoyant force.

Explanation of Solution

Force of buoyancy is the upward force that results when an object is fully or partially immersed in a fluid.

According to Archimedes’ principle, any object immersed wholly or partially in a fluid it experiences a force which is equal in magnitude to the weight of the volume of fluid that the object displaces.

The magnitude of buoyant force is given by Archimedes’ principle.

Conclusion:

Therefore, the word Archimedes’ principle can be picked from the list.
