Problem: Electric motor:

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 is current brought to the rotor in a synchronous motor?

A: Slip rings and brushes

Problem: Near East:

The populations of those lands did not accept Turkish rule. The Turks to them were foreigners with completely different customs, way of life, and language. Intervals when there was no unrest were rare. The Hungarians had thrown off Turkish rule by 1688. Serbia was created by the Serbian Revolution, 18151833. The Greek War of Independence, 18211832, created modern Greece, which recovered most of the lands of ancient Greece, but could not gain Constantinople. The Ottoman Porte was continuously under attack from some quarter in its empire, primarily the Balkans. Also, on a number of occasions in the early 19th century, American and British warships had to attack the Barbary pirates to stop their piracy and recover thousands of enslaved Europeans and Americans.

When was the Serbian Revolution?

A: 18151833

Problem: Cork (city):

The climate of Cork, like the rest of Ireland, is mild and changeable with abundant rainfall and a lack of temperature extremes. Cork lies in plant Hardiness zone 9b. Met Eireann maintains a climatological weather station at Cork Airport, a few kilometres south of the city. It should be noted that the airport is at an altitude of 151 metres (495 ft) and temperatures can often differ by a few degrees between the airport and the city itself. There are also smaller synoptic weather stations at UCC and Clover Hill.

Where are some weather stations near Cork?
