"Valence electrons are the outer electrons that are involved in bonding. Only electrons in the s and p orbitals are valance electrons, so a given atom can have between 0 and 7 valance electrons. Atoms ...
"The Newton's Third Law of Motion states that for every action there is an equal and opposite reaction. Simply put, it means that every force can be undone. Mathematically, it means that for every vec ...

"Transverse waves are waves which move particles in a direction perpendicular to the direction of a wave. An example of transverse waves are ocean waves in which water moves up and down, but does not ...
"Transformers are used to change one current into another current. Step up transformers increase the voltage of the current while step down transformers decrease the voltage. In power transmission, wh ...

"Insulators, also called dielectrics, don't conduct charge. In insulators, there is no conduction band so charge does not move to any appreciable extent. Dialectric strength, also called breakdown v ...
"Torque, also called movement of force, measures how much a force rotates an object around an axis. Torque is the cross product of the force vector and the vector of the distance from the axis. The fo ...
