"Orbital diagrams are pictorial descriptions of the electrons in an atom. Three rules are useful in forming orbital diagrams. According to the Auf Bau Principle, each electron occupies the lowest ener ...
"Ohm's law defines a concrete relationship between potential difference and current flow. This relationship is satisfied by all ohmic materials according to the equation potential difference = - curre ...

"Bernoulli's Principle replaces Pascal's Principle and liquid pressure for flowing fluid. It states that as you increase a fluid's speed, you decrease its the pressure that fluid exerts. Stagnant flui ...
"Newton's Law of Universal Gravitation says that everything with massive particle in the universe attracts all other massive particles. This force is called gravity. The force of gravity = universal g ...
"A barometer is a device used to measure pressure. Gauge pressure is the difference between a pressure and atmospheric pressure. Gauge pressure can be negative while total pressure cannot." Fuente: Br ...
