apparent weight and upthrust

Summary - Pressure at a point in a liquid depends upon the depth and on the density of the liquid. The pressure at any depth in a liquid acts equally in all directions. Liquids always find their own level. Pressure applied at any point in a confined liquid is transmitted equally in all the directio..

The stone weighed 0.67 N in air and 0.40 N when immersed in water. The displaced water weighed 0.27 N (= 0.67 - 0.40). Pour water into the can till the water starts overflowing through the spout. When the water stops dripping replace the beaker by another one of known weight. Suspend a..

When a body is immersed wholly or partially in a liquid (or fluid) at rest, it appears to lose some of its weight. The apparent loss in weight of the body is equal to the weight of liquid displace..

A cork is pushed down into water kept in a glass. We find that as soon as it is released, the cork rises on its own and comes to the surface. Pressure pushes cork upwards To keep it beneath the surface of water, we have to exert downward force. This means that, when the cork is under water, despite..

According to this principle, when a body is partially or wholly immersed in a fluid, it experiences an upthrust (buoyant force) equal to the weight of the liquid displace..

It is a matter of common experience that bodies appear lighter when immersed in water or any other liquid. While bathing we notice that the mug of water suddenly appears heavier as soon as it comes above the water surface. Similarly, when a fish is pulled out of water, it appears to be heavier in a..

A ship sinks in water until its weight is equal to the upthrust on it. This upthrust is the weight of the water displaced by the submerged part of the ship. The density of the sea varies in different parts of the world. This is due to the mineral salts dissol..

The underlying fact on which the principle is based was discovered by Archimedes in about 300 B.C. The story goes that the King of Sicily suspected that the goldsmith has mixed some silver in his crown and cheated him. Without destroying the crown he wanted to know the truth. Archimedes was asked ..

Record the observations as shown below: Weight of the sinker in air = W 1 gf Weight of the sinker in water = W 2 gf Weight of the sinker in liquid = W 3 gf Loss of weight of the sinker in water = (W 1 - W 2 ) gf Loss of weight of the sinker in ..

R.D of a Solid - R.D = Since weight is proportional to mass R.D When a body is immersed in water, it displaces its own volume of water. Upthrust on the body is equal to the weight of this displaced volume of water, which is also equal to loss of weight of the..
