when weight of the body is less than the wt. of the liq. it displaces it gets immersed by tht much portion by which wt. of the displaced liq. becomes equal to the wt. of the body.
plz explain this.

Weight of the body is always less than the weight of the liquid it displaces which is the buoyant force , if it has to float
It is the law of bouyancy ,
It states that:
" any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force the magnitude of which is equal to the weight of the fluid displaced by the body."
The buoyant force is equal to the weight of the displaced fluid

Take one glass bottle and one tumbler(plastic or else) filled with water. The tumbler must have a one side hole to flow the displaced waer. Keep the bottle sideways so that it is immersed in water. ( Care should be taken the water is not spilled out ). Weigh the water displaced and poured out (in another glass or else). It would be equal to the weight of the bottle. Next clean the same bottle and lid airtight with a cork and keep above the water in the tumbler after filling the tumbler again with same level. Some water is displaced and poured out. Bottle is not immersed. Now weigh the water, the weight would much less than the earlier weight of the displaced water. This shows the difference of the weight of the full bottle and part (immersed) of the bottle. (This can be also tested with the same mass of two things - stone and iron or wood etc.,- but same volume or size only. Different items displaces different quantity of water (so diff. weight). IF WEIGHT OF TWO BODIES ARE EQUAL (not size) THE weight of displaced water WOULD BE EQUALl (for water, it would be the same quantity)

it is the Archimedes's principle. It simply means that when we immerse any body in a liquid, the body will experience a up-word force equal to the weight of fluid displaced. Hence if this up-word force is = the weight of body then the body will remain in liquid where ever we place it (completely immersed) not going up or down. If it is less then the body will sink to the bottom. If more then the body will float and will pop out of the fluid just enough to balance its weight with the weight of displaced fluid

So I'm guessin we're talkin' about bouyancy right? Ok, here's how this works. Like you said, when the weight of the body is less than the weight of the liquid its surrounded by, the liquid displaces itself to make room for the weight of the body. When I say "make rook" I mean that it has to equally spread the addition of the body weight across it's entirety.
Look at it this way. When you stand in a puddle, you sink all the way to the botto. This is caused because you are too heavy for it. But when you're in a swimming pool, when you lay on your back you float. This is because your weight that you're adding to the water is being spread across the whole surface of the pool.
That help?

This is a physical law, namely Archimedes' Principle. And becuase it is a law, it just is. Like Newton's 2nd Law of Motion, which tells us that F=ma. Newton doesn't really know why this is so, and there is no need to know. Same goes for other laws such as the Biot-Savart Law, Coulumb's Law, Charles's Law, ect. These laws where formulated from experimental data, and the theorist need not know why his or her theory works.
In scientific philosophy, laws are JUST obeyed at a certain scope. Theories, on the other hand, such as the Theory of Relativity and the Thoery of Evolution by Natural Selection, attempts at explaining phenomena. Laws and principles do not do this. In short, thoeries attempt to answer the question "why?" and "why not?" while laws and principles simply attempt to answer the question "what?" and "how?".

First of all you know that an object that sinks displaces the amount of fluid equal to the objects volume.
An object will only float if it's less dense then the water.
Density = mass/Volume
If the object is less dense then it displaces water equal to it's weight instead of the volume.

terrible argument. in case you replaced "Christians" with "Athiests" then in line with threat i visit actually evaluate your question as genuine. even with the undeniable fact that maximum Christians do no longer declare to nicely known each and every thing. they think they have plenty to learn for this reason their purpose in existence is to approaches to be greater like God. while you're an Athiest then you definately're a tragic one as that to lift an argument as awful as that. and you besides mght might desire to nicely known which you would be able to no longer base your arguments on stereotypes.

It has to do with volume not weight.
