Problem: Please answer a question about the following article about Capacitor:
In single phase squirrel cage motors, the primary winding within the motor housing is not capable of starting a rotational motion on the rotor, but is capable of sustaining one. To start the motor, a secondary "start" winding has a series non-polarized starting capacitor to introduce a lead in the sinusoidal current. When the secondary (start) winding is placed at an angle with respect to the primary (run) winding, a rotating electric field is created. The force of the rotational field is not constant, but is sufficient to start the rotor spinning. When the rotor comes close to operating speed, a centrifugal switch (or current-sensitive relay in series with the main winding) disconnects the capacitor. The start capacitor is typically mounted to the side of the motor housing. These are called capacitor-start motors, that have relatively high starting torque. Typically they can have up-to four times as much starting torque than a split-phase motor and are used on applications such as compressors, pressure washers and any small device requiring high starting torques.
What sort of capacitors are used on the second winding of a squirrel cage motor?
A: series non-polarized starting capacitor
Problem: Please answer a question about the following article about Melbourne:
The city is recognised for its mix of modern architecture which intersects with an extensive range of nineteenth and early twentieth century buildings. Some of the most architecturally noteworthy historic buildings include the World Heritage Site-listed Royal Exhibition Building, constructed over a two-year period for the Melbourne International Exhibition in 1880, A.C. Goode House, a Neo Gothic building located on Collins Street designed by Wright, Reed & Beaver (1891), William Pitt's Venetian Gothic style Old Stock Exchange (1888), William Wardell's Gothic Bank (1883) which features some of Melbourne's finest interiors, the incomplete Parliament House, St Paul's Cathedral (1891) and Flinders Street Station (1909), which was the busiest commuter railway station in the world in the mid-1920s.
In what year was construction on the Flinders Street Station completed?
A: 1909
Problem: Please answer a question about the following article about Pope Paul VI:
Paul VI opened the third period on 14 September 1964, telling the Council Fathers that he viewed the text about the Church as the most important document to come out from the Council. As the Council discussed the role of bishops in the papacy, Paul VI issued an explanatory note confirming the primacy of the papacy, a step which was viewed by some as meddling in the affairs of the Council American bishops pushed for a speedy resolution on religious freedom, but Paul VI insisted this to be approved together with related texts such as ecumenism. The Pope concluded the session on 21 November 1964, with the formal pronouncement of Mary as Mother of the Church.
In what year did Paul VI formally appoint Mary as mother of the Catholic church?
A: 1964
Problem: Please answer a question about the following article about Humanism:
Better acquaintance with Greek and Roman technical writings also influenced the development of European science (see the history of science in the Renaissance). This was despite what A. C. Crombie (viewing the Renaissance in the 19th-century manner as a chapter in the heroic March of Progress) calls "a backwards-looking admiration for antiquity", in which Platonism stood in opposition to the Aristotelian concentration on the observable properties of the physical world. But Renaissance humanists, who considered themselves as restoring the glory and nobility of antiquity, had no interest in scientific innovation. However, by the mid-to-late 16th century, even the universities, though still dominated by Scholasticism, began to demand that Aristotle be read in accurate texts edited according to the principles of Renaissance philology, thus setting the stage for Galileo's quarrels with the outmoded habits of Scholasticism.
Closer examination of what information allowed for further progress in scientific knowledge?
A:
technical writings
