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.
When a driver brakes an automobile, the friction between the brake drums and the brake shoes converts the car's kinetic energy to thermal energy. If a 1800 kg automobile traveling
NEWTON'S THIRD LAW OF MOTION: This law can be described as "Actions and reactions are equal and opposite". OR To every action there is a

Explain about the Heat Extraction? a) A body of mass M has a temperature-independent precise heat C. If the body is heated reversibly from a temperature T i to a temperature
short answer
It has large energy gap 3.0ev and is regarded as high temperature semiconductor. It is extremely refectory subliming in the region of 2800 0 C. Because of large band gap it is hope
A 10.0-kg object is held up by a string that will break when the tension exceeds 1.00 x 10 2 N. At what upward acceleration will the string break?
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
