Electronvolt is equal to . It is a common unit of energy within physics, widely used in solid state, atomic, nuclear, and particle physics. It is commonly used with the metric prefixes milli-, kilo-, mega-, giga-, tera-, peta- or exa- (meV, keV, MeV, GeV, TeV, PeV and EeV respectively). In some older documents, and in the name Bevatron, the symbol BeV is used, which stands for billion (10) electronvolts; it is equivalent to the GeV. An electronvolt is the amount of energy gained (or lost) by the charge of a single electron moving across an electric potential difference of one volt.
Peta Nocona completely encompassed, every one fled his own way, and was hotly pursued and hard pressed. There are two distinct and very different stories about Peta Nocona's death. The first is that he died trying to escape with his wife and infant daughter, which is the generally believed story, and the one officially reported by Sul Ross.
