Any object, totally or partially immersed in a fluid or liquid, is buoyed up by a force equal to the weight of the fluid displaced by the object. Archimedes' principle allows the buoyancy of any floating object partially or fully immersed in a fluid to be calculated. The downward force on the object is simply its weight.
Buoyancy (/ ˈ b ɔɪ ən s i, ˈ b uː j ən s i /), [1] [2] or upthrust is a net upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.
Neutral buoyancy occurs when an object's average density is equal to the density of the fluid in which it is immersed, resulting in the buoyant force balancing the force of gravity that would otherwise cause the object to sink (if the body's density is greater than the density of the fluid in which it is immersed) or rise (if it is less).
To the north there are early medieval mentions of the French / Belgian River Maas being buoyed. [4] Such early buoys were probably just timber beams or rafts, but in 1358 there is a record of a barrel buoy in the Dutch Maasmond (also known as the Maas Sluis or Maasgat). [ 4 ]

An antonym is one of a pair of words with opposite meanings. Each word in the pair is the antithesis of the other. A word may have more than one antonym. There are three categories of antonyms identified by the nature of the relationship between the opposed meanings.
Hindi: कल and Urdu: کل (kal) may mean either "yesterday" or "tomorrow" (disambiguated by the verb in the sentence).; Icelandic: fram eftir can mean "toward the sea" or "away from the sea" depending on dialect.
An OE Buoy or Ocean Energy Buoy is a floating wave power device that uses an Oscillating Water Column design. It is being developed by Irish company Ocean Energy Ltd., based in Cork, in collaboration with the Hydraulics and Maritime Research Centre at University College Cork, Queen's University Belfast, and Marine Institute Ireland.
