Stokes' law explains why the speed of a raindrop is less than a freely falling body with constant velocity, from the height of clouds. The same law helps a man coming down with the help of a parachute, to slow down. Terminal velocity refers to the constant velocity, acquire..

Applications of Pascal's law - A hydraulic lift is used to lift heavy loads. It consists of two pistons of varying cross-sectional area. The two pistons are connected to each other with a horizontal pipe. The container is filled with an incompressible liquid. The load to be lift..

Applications of Kohlrausch's Law - Calculation of molar conductivity at infinite dilution (A o ) for weak electrolytes. Example: CH 3 COOH The value of for KCl, CH 3 COOK and HCl can be obtained by extrapolation (they are strong electrolytes..

In a cricket match a fielder moves his arms back while trying to catch a cricket ball because if he tries to stop the fast moving ball suddenly then the speed decreases to zero in a very short time. Therefore the retardation of the ball will be very large. As a result the fielder has to apply a lar..

This law is used in comparing the temperature of any two or more systems by the common use of thermometer. For example, in order to compare temperature of two bodies X and Y, the thermometer (analogous to body C) is allowed to come into thermal equilibrium first with body X and then with..

Hess's law has been useful in determining the heat changes of reactions, which cannot be measured directly with calorimeter. Some of its applications ar..

One of the important applications of Newton's law is to estimate masses of binary stars. A binary star is a system of two stars orbiting round their common center of mass. Any irregularity in the motion of a star indicates that it might be another star or a planet going round t..

In some cases of practical importance, symmetry considerations make it possible to use Amperes law to compute the magnetic field caused by a certain current carrying conduct..

Avogadro's law has been useful in substantiating a number of important laws and concepts. It has helped in the following areas: * In explaining Gay Lussac's law of gaseous volumes. * In determining the atomicity of gase..
