On the other hand, in the bullet's proper frame it is the moving fluid that becomes denser and hence the bullet would float. But the bullet cannot sink in one frame and float in another, so there is a paradox situation. The paradox was first formulated by James M. Supplee (1989), [1] where a non-rigorous explanation was presented.
In the "Sink or Float" YouTube game, Cookie Monster and his friend Emma ask for your help in testing whether five different objects will either sink or float in a tank of water.
Professor Myang-Li hosted a short segment in this series simply called "Sink or Float" in which she drops a piece of fruit into a pool and sees if it sinks or floats (similar to a future segment in Series 6 called "flush or float" where a piece of fruit is dropped into a toilet and the toilet is flushed to see if the fruit flushes down or not).
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).
The effect is observed in small objects which are supported by the surface of a liquid. There are two types of such objects: objects which are sufficiently buoyant that they will always float on the surface (for example, Cheerios in milk), and objects which are heavy enough to sink when immersed, but not so heavy as to overcome the surface tension of the liquid (for example, steel pins on water).
A teacher and a teenage student were killed in Monday’s shooting at the Abundant Life Christian School in Madison. Two students are in critical condition and four other students suffered non ...
Dr. Annie Harvilicz took in 41 animals at one point as wildfires spread across the Los Angeles area. Since, most have returned home or are being fostered.
A Cartesian diver or Cartesian devil is a classic science experiment which demonstrates the principle of buoyancy (Archimedes' principle) and the ideal gas law.The first written description of this device is provided by Raffaello Magiotti, in his book Renitenza certissima dell'acqua alla compressione (Very firm resistance of water to compression) published in 1648.
