principles of treatment

. This is called the principle of conservation of energy. The total mechanical energy is not constant for non-conservative forces such as frictional force..

Consider two simple harmonic sound waves each of amplitude A, frequencies f 1 and f 2 respectively, travelling in the same direction. Let y 1 and y 2 represent the individual displacements of a particle in the medium, that these waves can produce. Then the resultant displacement of the particl..

Analytical Treatment of Interference of Waves - Let two similar waves of amplitudes A 1 and A 2 having same frequency and wavelength travel past a point in a medium, producing individual displacements y 1 and y 2 . Then, , Where f is the phase difference between the waves at the point und..

The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around the nucleus in certain well-defined circular orbits. But the idea of uncertainty in position and velocity overruled the Bohr..

Biotechnology is science of manufacturing useful substances, chemicals, medicines by use of living organisms and their life process. In fact, biotechnology is not a new science. Alcohol was the first product manufactured by ancient biotechnologist. In recent years, biotechnology is growing as a sep..

The haemodialyzer or artificial kidney is a machine used to filter the blood of a person whose kidneys are damaged. The process is called haemodialysis. Haemodialysis is defined as the seperation of small molecules from large molecules in a solution by interposing a semipermeable membrane between t..

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., ..
