Floating and Sinking
Let W = Vrg be the true weight of body, acting through the centre of gravity and let 'w' be the weight of the liquid displaced, acting through the centre of gravity of the displaced liquid (called the centre of buoyancy..
Floating and Sinking
Let W = V r g be the true weight of body, acting through the centre of gravity and let 'w' be the weight of the liquid displaced, acting through the centre of gravity of the displaced liquid (called the centre of buoyancy). W-w = observed weight of the body immersed in a liquid (or fluid)..

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..

Buoyancy and Archimedes' Principle - 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 pul..

An iron needle sinks in water but a huge ship floats on the surface of water. All objects whether inside the liquid (or fluid) or partially inside, appear to be lighter than in air. This is because liquids (or fluids) exert upward force on the immersed object. This is called the upthrust,..

Hydrometer is an instrument used for determining the density of a liquid. It usually consists of a glass float with a long thin stem which is graduated. The glass float is a large hollow bulb which increases the buoyancy so that the hydrometer floats. The narrow stem increases the sensiti..

A submarine sinks by taking water into its buoyancy tanks. Once submerged, the upthrust is unchanged, but the weight of the submarine increases with the inflow of water and it sinks faster. Compressed air is used to blow water out of the tanks when it has to resurface..

Floating Bodies - Usually, all bodies less than that of water float, bodies which are denser than water sink. You might have noticed that a piece of steel sinks, but a ship made of steel floats. This is because of the design of the ship. The steel body of the ship encloses large..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor Vista tutors are pleasant and great to work with, they were very patient and explained everything that is simple to follow. I love working with them. - John Coakley
