An electron has momentum that is 90 % larger than its classical momentum. Find speed of electron.
Classical momentum Relativistic momentum Here m is effective mass
Given, Speed of electron v = 0.85 c.
Constantan: Constantan is a copper-nickel alloy. The amount of nickel in constantan is 40%. Properties: 1. It is silver like appearance. 2. Its electrical res
The phenomenon of the formation of the Newton's rings can be explained on the basis of wave theory of light. When a light ray iP1 from an extended monochromatic light source S is a

Rutherford's alpha-scattering experiment recognized that the mass of atom is concentrated with small positively charged region at the centre which is known as 'nucleus'. Nuclei
(i) Value of vibration of a particle is described as the number of vibrations done by particle in one second. (ii) It is the value of total wavelengths traversed by the wave in
I think it is same as the apex angle of the prism or the angle of the prism. since it decides the angle of deviation as i+e=D+A(angle of the prism),D=deviation.
Because of concentration difference holes or electron try to vary from their side to other side. Only these holes or electrons cross the junction, having high kinetic energy. This
how to calculate acceleration?
It is an instrument used to detect small current passing by it by showing deflection. Galvanometers are of dissimilar types e.g. moving coil galvanometer, moving magnet galvanomete
