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.
Define Electric Circuits So far we have only looked at electric charges sitting still and static discharges (like a shock or lightning). When we count on the charges moving thr
Displacement related with a wave is given by y (x, t) = 0.1 cos(0.2x-2t). Where x y are in cm and ‘t' in second. Determine the wavelength, amplitude, frequency and velocity.
Objective After studying this unit, you should be able to: 1. explain the importance of international trade; 2. discuss why a fm is motivated to export; 3. identify
The distance at any time because of any value of pulse meeting concurrently at a position in a medium is the vector addition of the individual distances due every one of the ray at
UV radiations and X - rays are: UV radiations are produced by the high energy transitions of the electrons in atoms. UV radiations have wavelengths ranging from 0.4 m m to 1n
Q. Illustrate how is nuclear fission different from nuclear fusion? Answer:- Nuclear fusion is taking two different atoms as well as combining them in to one atom while nu

Hi i am doing research right now on anti-matter. I am just wondering if it is present in the human body?
#question.A tortoise can run with a speed of 0.12 m/s, and a hare can run 20 times as fast. In a race, they both start at the same time, but the hare stops to rest for 4.0 minutes.
