  335. 335. What are buoyant forces?XI. Buoyancy is the force of a liquid pushing up on an object. Buoyant Force of water pushes up.
  336. 336. What are buoyant forces?A. Buoyant force is equal to gravity when an object floats. Force of Gravity pushes down. Buoyant Force of water pushes up.
  337. 337. What are buoyant forces?A. Buoyant force is equal to gravity when an object floats. Force of Gravity pushes down. Buoyant Force of water pushes up.
  338. 338. What are buoyant forces?B. When an object is flat, Buoyancy is greater because the liquid pushes up against a larger surface area. Buoyant Forces of liquid push up.
