QUES: Classical statistical mechanics requires the existence of h (but does not define its value). Eventually, following upon Planck's discovery, it was recognized that physical action cannot take on an arbitrary value. Instead, it must be some multiple of a very small quantity, the "quantum of action", now called the Planck constant. Classical physics cannot explain this fact. In many cases, such as for monochromatic light or for atoms, this quantum of action also implies that only certain energy levels are allowed, and values in between are forbidden.
What is the Planck constant incorrectly known as?

ANS: unanswerable

QUES: However, Eritrea still faces many challenges. Despite number of physicians increasing from only 0.2 in 1993 to 0.5 in 2004 per 1000 population, this is still very low. Malaria and tuberculosis are common in Eritrea. HIV prevalence among the 1549 group exceeds 2%. The fertility rate is at about 5 births per woman. Maternal mortality dropped by more than half from 1995 to 2002, although the figure is still high. Similarly, between 1995 and 2002, the number of births attended by skilled health personnel has doubled but still is only 28.3%. A major cause of death in neonates is by severe infection. Per capita expenditure on health is low in Eritrea.
As of 2002, how many births were attended by skilled health personnel in Eriterea?

ANS: 28.3%

QUES: The second and most dramatic boom and bust resulted from the Klondike Gold Rush, which ended the depression that had begun with the Panic of 1893; in a short time, Seattle became a major transportation center. On July 14, 1897, the S.S. Portland docked with its famed "ton of gold", and Seattle became the main transport and supply point for the miners in Alaska and the Yukon. Few of those working men found lasting wealth, however; it was Seattle's business of clothing the miners and feeding them salmon that panned out in the long run. Along with Seattle, other cities like Everett, Tacoma, Port Townsend, Bremerton, and Olympia, all in the Puget Sound region, became competitors for exchange, rather than mother lodes for extraction, of precious metals. The boom lasted well into the early part of the 20th century and funded many new Seattle companies and products. In 1907, 19-year-old James E. Casey borrowed $100 from a friend and founded the American Messenger Company (later UPS). Other Seattle companies founded during this period include Nordstrom and Eddie Bauer. Seattle brought in the Olmsted Brothers landscape architecture firm to design a system of parks and boulevards.
What company did James E. Casey found in 1907 with a borrowed $100?

ANS: American Messenger Company

QUES: In 1949, France started its transmissions with an 819 lines system (with 737 active lines). The system was monochrome only, and was used only on VHF for the first French TV channel. It was discontinued in 1983.
What country started transmissions using and 819 line system in 1959?
