It was mentioned earlier that, displacement vectors are added to displacement vectors, or velocity vectors are added to velocity vectors. Just as it is meaningless to add scalar quantities of different kinds, such as mass and temperature, so also it is meaningless to add vector quantities of diffe..

>Later, Joule's work lead to a new branch of physics known as thermodynamics conversion of heat energy into mechanical energy. In fact any form of energy, mechanical, electrical, chemical energy can be very easily converted to heat energy. Similarly, heat energy may also be conv..

It is a nuclear phenomenon. It is due to the instability of the nucleus. It is a spontaneous, continuous and irreversible process. It is independent of external factors such as pressure, temperature, state of substance, electrical field, magnetic field, catalyst etc. A radioactive ele..

If y 1 0 be the distance of the 10 t h bright fringe from the central fringe, then, Let n t h bright fringe be formed at the same place when the new wavelength is 5000 A But y n = y 1 0 ( g i v e n ) On simplification, n=14 Thus, 14 t h order bright fringe will be ..

A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity is called Radioactive decay or disintegration. When..

Superposition Principle of Waves - When two or more wave motions traveling through a medium superimpose one another, a new wave is formed whose resultant displacement at any instant is equal to the vector sum of the displacement due to individual waves at that instant The two short lined ..

Wavelength, Frequency and Time Period - Wavelength, frequency and time period describe a wave. Now let us define these terms. Wavelength is defined as the distance between the two nearest points on the wave or it can be defined as the distance between two consecutive crests or troughs in the case o..
