Question: A P-N junction can convert absorbed light energy into a proportional electric current. The same process is reversed here (i.e. the P-N junction emits light when electrical energy is applied to it). This phenomenon is generally called electroluminescence, which can be defined as the emission of light from a semi-conductor under the influence of an electric field. The charge carriers recombine in a forward-biased P-N junction as the electrons cross from the N-region and recombine with the holes existing in the P-region. Free electrons are in the conduction band of energy levels, while holes are in the valence energy band. Thus the energy level of the holes will be lesser than the energy levels of the electrons. Some portion of the energy must be dissipated in order to recombine the electrons and the holes. This energy is emitted in the form of heat and light.
Try to answer this question if possible: Why is some energy in the electroluminescence process emitted as heat and light?
Answer: to recombine the electrons and the holes
Question: The Knights of Columbus, the world's largest Catholic fraternal service organization and a Fortune 1000 company, is headquartered in New Haven. Two more Fortune 1000 companies are based in Greater New Haven: the electrical equipment producers Hubbell, based in Orange, and Amphenol, based in Wallingford. Eight Courant 100 companies are based in Greater New Haven, with four headquartered in New Haven proper. New Haven-based companies traded on stock exchanges include NewAlliance Bank, the second largest bank in Connecticut and fourth-largest in New England (NYSE: NAL), Higher One Holdings (NYSE: ONE), a financial services firm United Illuminating, the electricity distributor for southern Connecticut (NYSE: UIL), Achillion Pharmaceuticals (NASDAQ: ACHN), Alexion Pharmaceuticals (NasdaqGS: ALXN), and Transpro Inc. (AMEX: TPR). Vion Pharmaceuticals is traded OTC (OTC BB: VIONQ.OB). Other notable companies based in the city include the Peter Paul Candy Manufacturing Company (the candy-making division of the Hershey Company), the American division of Assa Abloy (one of the world's leading manufacturers of locks), Yale University Press, and the Russell Trust Association (the business arm of the Skull and Bones Society). The Southern New England Telephone Company (SNET) began operations in the city as the District Telephone Company of New Haven in 1878; the company remains headquartered in New Haven as a subsidiary of AT&T Inc., now doing business as AT&T Connecticut, and provides telephone service for all but two municipalities in Connecticut.
Try to answer this question if possible: What is the name of the second largest bank found in Connecticut?
Answer: NewAlliance Bank
Question: Religion is extremely important to the Tibetans and has a strong influence over all aspects of their lives. Bon is the ancient religion of Tibet, but has been almost eclipsed by Tibetan Buddhism, a distinctive form of Mahayana and Vajrayana, which was introduced into Tibet from the Sanskrit Buddhist tradition of northern India. Tibetan Buddhism is practiced not only in Tibet but also in Mongolia, parts of northern India, the Buryat Republic, the Tuva Republic, and in the Republic of Kalmykia and some other parts of China. During China's Cultural Revolution, nearly all Tibet's monasteries were ransacked and destroyed by the Red Guards. A few monasteries have begun to rebuild since the 1980s (with limited support from the Chinese government) and greater religious freedom has been granted although it is still limited. Monks returned to monasteries across Tibet and monastic education resumed even though the number of monks imposed is strictly limited. Before the 1950s, between 10 and 20% of males in Tibet were monks.

Answer: Bon
Question: The Quran and Muhammad talked about racial equality and justice as in The Farewell Sermon. Tribal and nationalistic differences were discouraged. But after Muhammad's passing, the old tribal differences between the Arabs started to resurface. Following the RomanPersian Wars and the ByzantineSassanid Wars, deep rooted differences between Iraq, formally under the Persian Sassanid Empire, and Syria, formally under the Byzantine Empire, also existed. Each wanted the capital of the newly established Islamic State to be in their area. Previously, the second caliph Umar was very firm on the governors and his spies kept an eye on them. If he felt that a governor or a commander was becoming attracted to wealth, he had him removed from his position.
Try to answer this question if possible: Who was soft on the governors?
