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.
Tera language Tera language Tera is a Chadic dialect cluster spoken in north-eastern Nigeria in the north and eastern parts of Gombe State and Borno State. Blench (2006) believes Pidlimdi (Hinna) dialect is a separate language. Vowel length contrasts are neutralized in monosyllabic words with no coda consonants.
