What physical factors determine the magnitude of buoyant force___________________?
Show answer Hide answer
Answer: A. mass of liquid displaced
Explanation
Archimedes principle establishes that buoyant force equals the weight of displaced liquid. The mass of the liquid displaced directly determines the magnitude of this upward force. Changes in displaced mass alter the resultant buoyant force acting on the submerged object. Buoyancy is an upward force exerted by fluids on objects placed within them. Mass depends directly on the volume of the displaced fluid and its specific density. Gravity acts upon this displaced fluid mass to generate the supporting upward pressure.
Naval architects use displaced mass calculations to determine cargo capacity limits for ships. Hot air balloons rise because heated air inside weighs less than the displaced atmosphere. Hydrometers measure liquid density by observing the mass of fluid they successfully displace. Liquid viscosity affects flow resistance rather than the static magnitude of buoyant force. Pressure varies with depth, but total buoyant force depends on net displaced mass volume. Depth of immersion alone does not dictate buoyancy unless it alters displaced fluid volume.
