What force in fluids described by Archimedes'principle allows objects to float?
bouyancy
What is the force which supports objects in fluid?
The property of bouyancy is the property related to keeping objects supported in fluids.
Why does the heat rise in convection?
There is a general tendency for objects to expand when they get hotter - this includes air, and gases in general. As a result, they have less density (mass per unit volume); and objects with less density tend to float or rise.
What must have a definite shape?
Three dimensional solid objects. Fluids (liquids and gasses) take the shape of any container they are enclosed in
What two scientific laws or principles contribute to the total amount of lift?
The Bernoulli principle - faster moving fluids have less pressure than slower moving fluids Newton's third law of motion - for every action there is an equal and opposite reaction.
Which force in fluids described by Archimedes's principle allows objects to float?
buoyancy
What force in fluids described by Archimedes'principle allows objects to float?
bouyancy
How does Archimedes principle relate the buoyant force acting on an object to the fluids displaced by the object?
The weight of the bouyant force and the fluid displaced by the object are equal.
What type of scientist was Archimedes?
Archimedes was a Physics Fluids Scientist. Dates: 287-212 BC. The description of his scientific law is the Principle of Displacement, when a body is totally or partially immersed in a fluid it experiences an upthrust equal to the weight of the fluid displaced. Principle of Flotation, when a body floats it displaces a weight of fluid equal its own weight.
Why a ship which is made of heavy steel does not sink?
This is explained following Archimedes' principle; that is named after Archimedes of Syracuse who first discovered this law in 212 B.C.For more objects, floating and sunken, and generally in fluids; Archimedes' principle may be stated thus in terms of forces that; according to Archimedes; sates that "Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object".It is to be clarified that for a sunken object the volume of displaced fluid is the volume of the object, and for a floating object on a liquid, the weight of the displaced liquid is the weight of the object.More specifically: Buoyancy = weight of displaced fluid.In simple terms, the principle states that the buoyancy force on an object is going to be equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g.Thus, among completely submerged objects with equal masses, objects with greater volume have greater buoyancy. This explains why the ship floats although made of heavy steel because it has bigger volume and accordingly is having higher buoyancy that keeps it floating.
What force in fluids allows objects to float?
Buoyancy
Energy is usually transferred in fluids by radiation?
No, the principle method of heat transfer in fluids is convection, as the most energetic molecules rise towards the surface and the least energetic sink. Radiation is most significant for objects which are very hot, even glowing.
When objects are layered do objects of higher or lower density sink to the bottom?
The fluids with highest densities form the lowest layers. The fluids with lowest densities form the highest layers.
Why objects moving in fluids must have special shapes?
When objects move through fluids, they have to overcome friction acting on them. In this process they lose energy. Efforts are, therefore, made to minimise friction. So , objects are given special shapes.
What is the force which supports objects in fluid?
The property of bouyancy is the property related to keeping objects supported in fluids.
What is the principle of hay's test?
bile salts lowers the surface tension of fluids like urine. sulphur in fluids with specific gravity of 1.020 and below.
What is the force that pulls objects up in the water?
Objects in water or other fluids can be pushed up to the surface by buoyancy.
