WebJan 24, 2024 · The ship can float in a partially submerged state as the buoyant force will be equal in the magnitude of the ship’s weight. The density of hot air is less than the density of ambient cool air. This concept is used in hot air balloons so that it can float in the air. Solved Examples on Buoyancy Formula Q.1. WebAug 16, 2024 · The average density of an object is what ultimately determines whether it floats. If its average density is less than that of the surrounding fluid, it will float. This is because the fluid, having a higher density, contains more mass and hence more weight in the same volume.
WebOct 30, 2024 · For an object to float, the buoyant force, the force pointing upwards, has to be equal to or greater than the force of gravity on an object. Otherwise, the object will accelerate downwards and sink. WebMost eye floaters are caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes liquifies and contracts.
