Vs. System. 1 Some casual rules allow more players. Vs. System (short for Versus System ), also written as VS System and abbreviated as VS, is a collectible card game designed by Upper Deck Entertainment (UDE). [ 1] In the game, players build and play a deck of Vs. System cards in an attempt to win a game against their opponent.
The Dirac sea is a theoretical model of the electron vacuum as an infinite sea of electrons with negative energy, now called positrons. It was first postulated by the British physicist Paul Dirac in 1930 [1] to explain the anomalous negative-energy quantum states predicted by the relativistically-correct Dirac equation for electrons. [2]
Gravitational energy, or gravitational potential energy, is the potential energy a massive object has because it is within a gravitational field. In classical mechanics, two or more masses always have a gravitational potential. Conservation of energy requires that this gravitational field energy is always negative, so that it is zero when the ...
In the Arrhenius model of reaction rates, activation energy is the minimum amount of energy that must be available to reactants for a chemical reaction to occur. [1] The activation energy ( Ea) of a reaction is measured in kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol). [2] Activation energy can be thought of as the magnitude ...
The triboelectric effect (also known as triboelectricity, triboelectric charging, triboelectrification, or tribocharging) describes electric charge transfer between two objects when they contact or slide against each other. It can occur with different materials, such as the sole of a shoe on a carpet, or between two pieces of the same material.
The health threat depends on the flux, energy spectrum, and nuclear composition of the radiation. The flux and energy spectrum depend on a variety of factors: short-term solar weather, long-term trends (such as an apparent increase since the 1950s [28]), and position in the Sun's magnetic field. These factors are incompletely understood.
A standard 52-card French-suited deck comprises 13 ranks in each of the four suits: clubs ( ♣ ), diamonds ( ♦ ), hearts ( ♥) and spades ( ♠ ). Each suit includes three court cards (face cards), King, Queen and Jack, with reversible (i.e. double headed) images. Each suit also includes ten numeral cards or pip cards, from one (Ace) to ten.
Negative number. This thermometer is indicating a negative Fahrenheit temperature (−4 °F). In mathematics, a negative number represents an opposite. [ 1] In the real number system, a negative number is a number that is less than zero. Negative numbers are often used to represent the magnitude of a loss or deficiency.
