ENERGY LEVELS
The energy levels, measured in electron volts (e.v.) in which orbiting electrons exist comply with a law of physics which states that energy can be given to electrons only in discrete amounts (quanta) which means that there are energy values that an electron cannot acquire. From this it can be deducted that there is a forbidden energy gap between each of the allowed energy bands K to O.
The width of the forbidden energy gap between the top of the valence band and the bottom of the conduction band determine the electrical conducting properties of materials.
what happens to a conical pendulum when the bob splits into two parts such that one part remains attached to the string?
what is an ideal dipole
Determinism principle It is the principle that if one knows the state to an infinite accuracy of a system at one point in time, one would be capable to know about the state of
Ans) In the first one..... F=ma...the only force which acts is F...which causes an acc. of ''a'' to the body of mass m... and as the force=>F=ma but on the second... let .
Why does heated air expand? Temperature is often explained as the average thermal energy of the substance at hand. Therefore the hotter a substance is the more thermal energy i
