QUES: A synchronous electric motor is an AC motor distinguished by a rotor spinning with coils passing magnets at the same rate as the AC and resulting magnetic field which drives it. Another way of saying this is that it has zero slip under usual operating conditions. Contrast this with an induction motor, which must slip to produce torque. One type of synchronous motor is like an induction motor except the rotor is excited by a DC field. Slip rings and brushes are used to conduct current to the rotor. The rotor poles connect to each other and move at the same speed hence the name synchronous motor. Another type, for low load torque, has flats ground onto a conventional squirrel-cage rotor to create discrete poles. Yet another, such as made by Hammond for its pre-World War II clocks, and in the older Hammond organs, has no rotor windings and discrete poles. It is not self-starting. The clock requires manual starting by a small knob on the back, while the older Hammond organs had an auxiliary starting motor connected by a spring-loaded manually operated switch.
How can a synchronous motor be made more like an induction motor?

ANS: DC field

QUES: The style of Georgian buildings is very variable, but marked by a taste for symmetry and proportion based on the classical architecture of Greece and Rome, as revived in Renaissance architecture. Ornament is also normally in the classical tradition, but typically rather restrained, and sometimes almost completely absent on the exterior. The period brought the vocabulary of classical architecture to smaller and more modest buildings than had been the case before, replacing English vernacular architecture (or becoming the new vernacular style) for almost all new middle-class homes and public buildings by the end of the period.
And what type of architecture is ornament normally not restrained?

ANS: unanswerable

QUES: Atkins, a former member of Cybotron, released Model 500 "No UFOs" in 1985, which became a regional hit, followed by dozens of tracks on Transmat, Metroplex and Fragile. One of the most unusual was "Strings of Life" by Derrick May, a darker, more intellectual strain of house. "Techno-Scratch" was released by the Knights Of The Turntable in 1984 which had a similar techno sound to Cybotron. The manager of the Factory nightclub and co-owner of the Haçienda, Tony Wilson, also promoted acid house culture on his weekly TV show. The Midlands also embraced the late 1980s house scene with illegal parties and more legal dance clubs such as The Hummingbird.
What did Knights of the turntable release in 1980?

ANS: unanswerable

QUES: Official figures (as of July 21, 2008 12:00 CST) stated that 69,197 were confirmed dead, including 68,636 in Sichuan province, and 374,176 injured, with 18,222 listed as missing. The earthquake left about 4.8 million people homeless, though the number could be as high as 11 million. Approximately 15 million people lived in the affected area. It was the deadliest earthquake to hit China since the 1976 Tangshan earthquake, which killed at least 240,000 people, and the strongest in the country since the 1950 Chayu earthquake, which registered at 8.5 on the Richter magnitude scale. It is the 21st deadliest earthquake of all time. On November 6, 2008, the central government announced that it would spend 1 trillion RMB (about US $146.5 billion) over the next three years to rebuild areas ravaged by the earthquake, as part of the Chinese economic stimulus program.
How much money was dedicated to rebuild ravaged areas?

ANS:
1 trillion RMB
