Both arc and arch come from the Latin element arcus, "bow". Archery and archer also come from this same Latin element.

2. The boat mentioned in the Bible which God commanded Noah to build for shelter during the Great Flood: Noah was commanded to build an ark, big enough for two of each species of animals, in anticipation of the flood.
3. A large, flat-bottomed or awkward boat: They lived on an ark, or house boat, on the Seine River in Paris.
When Wilbur decided to move off the isolated island, he determined to build an ark to carry his possessions. The builder designed the ark using a long arc shaped bow.
Beta arc refers to arousal of higher cortical paths by the functioning of an alpha arc; thus, leading to a "sensation" rather than simple "awareness", and not by an outside stimulus directly.
The term alpha arc is approximately equivalent to immediate response in Watson's behavioristic psychology, while the term beta arc is roughly equivalent to Watson's delayed response or implicit behavior.
Arc lamps are used to produce intense light; such as, in spotlights and to produce heat for welding.
2. A luminous discharge of current that is formed when a strong current jumps a gap in a circuit or between two electrodes.
Electric arcs across specially designed electrodes can produce very high heat and bright light, and are used for such purposes as welding and illumination in spotlights.
Unwanted arcs in electrical circuits can cause fires and lightning is an example of an electric arc between one cloud and the earth or another cloud, as are sparks caused by discharges of static electricity.
2. A furnace used to heat materials with the energy from an electric arc.
3. An electric furnace in which an electric arc provides the source of heat for making steel.
4. A steel-making apparatus which uses high-quality scrap or ore with the polluting elements eliminated.
2. The heating of matter by an electric arc.
The material may be solid, liquid, or gaseous and when the heating is direct, the material to be heated is one electrode; but for indirect heating, the heat is transferred from the arc by conduction, convection, or radiation.
2. A general term for a class of lamps which produce light by an electric arc or a voltaic arc.
The lamp consists of two electrodes, typically made of tungsten, that are separated by a gas.
2. Welding in which the joint is heated to fusion by an electric arc or by a large electric current.
3. The joining of metal components by fusing them with heat from an electrical arc struck between two electrodes.
2. Arcing across satellite antenna terminals as the satellite passes through the ionized regions of the ionosphere.
3. An electric spark which is created when ionized charges build up in a medium and produce forces on the electrons.
An arc minute (symbol ') is one-sixtieth of a degree, and an arc second (symbol ") is one-sixtieth of an arc minute. Small distances in the sky, as between two close stars or the apparent width of a planet's disk, are expressed in minutes and seconds of arc.
