Whereas SCIMs cannot turn a shaft faster than allowed by the power line frequency, universal motors can run at much higher speeds. This makes them useful for appliances such as blenders, vacuum cleaners, and hair dryers where high speed and light weight are desirable. They are also commonly used in portable power tools, such as drills, sanders, circular and jig saws, where the motor's characteristics work well. Many vacuum cleaner and weed trimmer motors exceed 10,000 rpm, while many similar miniature grinders exceed 30,000 rpm.
At around what RMP do miniature grinders operate?
****
The answer: 30,000


The problem: Answer a question about this article:
Economic and political migrations made an impact across the empire. For example, the Russian and Austria-Habsburg annexation of the Crimean and Balkan regions respectively saw large influxes of Muslim refugees – 200,000 Crimean Tartars fleeing to Dobruja. Between 1783 and 1913, approximately 5–7 million refugees flooded into the Ottoman Empire, at least 3.8 million of whom were from Russia. Some migrations left indelible marks such as political tension between parts of the empire (e.g. Turkey and Bulgaria) whereas centrifugal effects were noticed in other territories, simpler demographics emerging from diverse populations. Economies were also impacted with the loss of artisans, merchants, manufacturers and agriculturists. Since the 19th century, a large proportion of Muslim peoples from the Balkans emigrated to present-day Turkey. These people are called Muhacir. By the time the Ottoman Empire came to an end in 1922, half of the urban population of Turkey was descended from Muslim refugees from Russia.
In what year did the Ottoman Empire end?
****
The answer: 1922


The problem: Answer a question about this article:
Along with secular matters, readers also favoured an alphabetical ordering scheme over cumbersome works arranged along thematic lines. The historian Charles Porset, commenting on alphabetization, has said that "as the zero degree of taxonomy, alphabetical order authorizes all reading strategies; in this respect it could be considered an emblem of the Enlightenment." For Porset, the avoidance of thematic and hierarchical systems thus allows free interpretation of the works and becomes an example of egalitarianism. Encyclopedias and dictionaries also became more popular during the Age of Reason as the number of educated consumers who could afford such texts began to multiply. In the later half of the 18th century, the number of dictionaries and encyclopedias published by decade increased from 63 between 1760 and 1769 to approximately 148 in the decade proceeding the French Revolution (1780–1789). Along with growth in numbers, dictionaries and encyclopedias also grew in length, often having multiple print runs that sometimes included in supplemented editions.
How many dictionaries and encyclopedias were published in the decade preceding the French Revolution?
****
The answer: 148


The problem: Answer a question about this article:
Upon his election to the papacy, Montini took the pontifical name Paul VI (the first to take the name "Paul" since 1605) to indicate a renewed worldwide mission to spread the message of Christ, following the example of Apostle St. Paul.[citation needed] He re-convened the Second Vatican Council, which was automatically closed with the death of John XXIII, and gave it priority and direction. After the council had concluded its work, Paul VI took charge of the interpretation and implementation of its mandates, often walking a thin line between the conflicting expectations of various groups within Catholicism. The magnitude and depth of the reforms affecting all fields of Church life during his pontificate exceeded similar reform policies of his predecessors and successors. Paul VI was a Marian devotee, speaking repeatedly to Marian congresses and mariological meetings, visiting Marian shrines and issuing three Marian encyclicals. Following his famous predecessor Saint Ambrose of Milan, he named Mary as the Mother of the Church during the Second Vatican Council. Paul VI sought dialogue with the world, with other Christians, other religions, and atheists, excluding nobody. He saw himself as a humble servant for a suffering humanity and demanded significant changes of the rich in North America and Europe in favour of the poor in the Third World. His positions on birth control, promulgated most famously in the 1968 encyclical Humanae vitae, and other political issues, were often controversial, especially in Western Europe and North America.
In what year was the name "Paul" last used as a pontifical name before Pope Paul VI became Pope?
****
The answer:
1605
