The total energy of a particle, executing simple harmonic motion isAns) In simple harmonic motion when a particle is displaced to a position from its mean position, then its kinetic energy gets converted into potential energy and vice-versa. Therefore, total energy of a particle remains constant or the total energy in simple harmonic motion does not depend on displacement x.

What is intramodal dispersion in optical fibres? Intramodal dispersion (Δτ mat ) Intramodal dispersion is nothing although material dispersion. The velocity dissimilarity of
what is the measuring range of a photometer?
Majority and minority charge carriers A pure semiconductor has equal number of holes and electrons. But an extrinsic semiconductor has majority charge carriers. When a tri
what different is between photons? Answer; the difference between photons depends to their frequency, and frequency depends to the number of CPH in structure of photon. Thus
The decrease of mass is related to the binding of the individual particles together inside the nucleus. Therefore every stable nucleus has a mass which is less than the total ma
