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.
RANGE OF PROJECTILE: "It is the horizontal distance covered by the projectile from the point of projection to the point where it returns to its level of projection".
NEWTON'S FIRST LAW OF MOTION: This law states that "A body at rest will remain at rest and a body moving with uniform velocity will carry on doing so, until acted on by some un
Five people are playing tug-of-war. Anders and Alyson pull to the right with 45 N and 35 N, respectively. Calid and Marisol pull to the left with 53 N and 38 N, respectively.
Defect: The image is formed behind the retina and lens becomes converging.

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.
Does upthrust change in different liquids (examples please)
what happens if lc oscillations circuit is placed in dielectric chamber?
a. A certain radioactive material emits gamma rays with energy 1 MeV. Another sample of radioactive material emits gamma rays with energy 10 keV. If both of these emit the same amo
