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.
A cheetah can reach a top speed of 27.8 m/s in 5.2 s. What is the cheetah's average acceleration?
The characteristic of a body by virtue of which the body takes its real configuration when external deforming forces are removed is called as elasticity.
how would the results change if the angle of the third load in second experiment increased ? state the differences
The birghtness of objects past Neptune actually varies approximately as 1/d^4. Why is that the case?
Consider a circular loop in a magnetic field. The loop is made of elastic material with spring constant k. It carries a current I and has radius R when unstretched. We immerse it i
