Question: The Great Plains lie west of the Mississippi River and east of the Rocky Mountains. A large portion of the country's agricultural products are grown in the Great Plains. Before their general conversion to farmland, the Great Plains were noted for their extensive grasslands, from tallgrass prairie in the eastern plains to shortgrass steppe in the western High Plains. Elevation rises gradually from less than a few hundred feet near the Mississippi River to more than a mile high in the High Plains. The generally low relief of the plains is broken in several places, most notably in the Ozark and Ouachita Mountains, which form the U.S. Interior Highlands, the only major mountainous region between the Rocky Mountains and the Appalachian Mountains.
Try to answer this question if possible: How high does elevation rise in the Great Plains?
Answer: a mile high
Question: St. John's is located along the coast of the Atlantic Ocean, on the northeast of the Avalon Peninsula in southeast Newfoundland. The city covers an area of 446.04 square kilometres (172.22 sq mi) and is the most easterly city in North America, excluding Greenland; it is 295 miles (475 km) closer to London, England than it is to Edmonton, Alberta. The city of St. John's is located at a distance by air of 3,636 kilometres (2,259 mi) from Lorient, France which lies on a nearly precisely identical latitude across the Atlantic on the French western coast. The city is the largest in the province and the second largest in the Atlantic Provinces after Halifax, Nova Scotia. Its downtown area lies to the west and north of St. John's Harbour, and the rest of the city expands from the downtown to the north, south, east and west.
Try to answer this question if possible: What french city is 3,636 miles from St. Johns?
Answer: unanswerable
Question: Executive authority in Bermuda is vested in the monarch and is exercised on her behalf by the Governor. The governor is appointed by the Queen on the advice of the British Government. The current governor is George Fergusson; he was sworn in on 23 May 2012. There is also a Deputy Governor (currently David Arkley JP). Defence and foreign affairs are carried out by the United Kingdom, which also retains responsibility to ensure good government. It must approve any changes to the Constitution of Bermuda. Bermuda is classified as a British Overseas Territory, but it is the oldest British colony. In 1620, a Royal Assent granted Bermuda limited self-governance; its Parliament is the fifth oldest in the world, behind the Parliament of the United Kingdom, the Tynwald of the Isle of Man, the Althing of Iceland, and Sejm of Poland. Of these, only Bermuda's and the Isle of Man's Tynwald have been in continuous existence since 1620.
Try to answer this question if possible: Who appoints the Governor of Bermuda?
Answer: the Queen on the advice of the British Government.
Question: Stepper motors are a type of motor frequently used when precise rotations are required. In a stepper motor an internal rotor containing PMs or a magnetically soft rotor with salient poles is controlled by a set of external magnets that are switched electronically. A stepper motor may also be thought of as a cross between a DC electric motor and a rotary solenoid. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding. Unlike a synchronous motor, in its application, the stepper motor may not rotate continuously; instead, it "steps"starts and then quickly stops againfrom one position to the next as field windings are energized and de-energized in sequence. Depending on the sequence, the rotor may turn forwards or backwards, and it may change direction, stop, speed up or slow down arbitrarily at any time.
Try to answer this question if possible: How does a stepper motor differ from a synchronous motor?
Answer:
the stepper motor may not rotate continuously
