areas of law

Whenever the amount of magnetic flux linked with a circuit changes, an EMF is induced in the circuit. This induced EMF lasts so long as the change in magnetic flux continues. EMF induced in a circuit is directly proportional to the rate of change of magnetic flux linked with the circuit, i.e., ..

Friction always acts in such a direction that it opposes the motion. Force of friction is directly proportional to normal reaction. Until motion takes place, the static friction adjusts itself so as to be equal to the force tending to produce motion. In any given case, there is a limiting v..

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 gases. In determining the molecular formula of a..

Ampere's law is a useful relation that is analogous to Gauss's law. Ampere's law is a relationship between the tangential component of magnetic field at points on a closed curve and the net current through the area bounded by the curv..

Ampere's Circuital Law - Ampere's law is a useful relation that is analogous to Gauss's law. Ampere's law is a relationship between the tangential component of magnetic field at points on a closed curve and the net current through the area bounded b..

The study of reactions is one of the important areas of Chemistry. There are many aspects of a reaction like the rate of reaction, energy absorbed or evolved, mechanism of a reaction that can be evaluated only with weight and volume relationships. A study of reactions is possible by..

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 pip..

Consider a spherical vessel having four cylindrical tubes A, B, C and D, each fitted with airtight frictionless piston, of area of cross-section 4a, 3a, 2a and a, respectively. When the vessel is filled with an incompressible liquid so that no air gap is left inside the vessel, ..
