Problem: Electric motor:

A servomotor is a motor, very often sold as a complete module, which is used within a position-control or speed-control feedback control system mainly control valves, such as motor-operated control valves. Servomotors are used in applications such as machine tools, pen plotters, and other process systems. Motors intended for use in a servomechanism must have well-documented characteristics for speed, torque, and power. The speed vs. torque curve is quite important and is high ratio for a servo motor. Dynamic response characteristics such as winding inductance and rotor inertia are also important; these factors limit the overall performance of the servomechanism loop. Large, powerful, but slow-responding servo loops may use conventional AC or DC motors and drive systems with position or speed feedback on the motor. As dynamic response requirements increase, more specialized motor designs such as coreless motors are used. AC motors' superior power density and acceleration characteristics compared to that of DC motors tends to favor PM synchronous, BLDC, induction, and SRM drive applications.

What must be well understood when applying a servo motor for use?
---
A: speed, torque, and power


Problem: Washington University supports four major student-run media outlets. The university's student newspaper, Student Life, is available for students. KWUR (90.3 FM) serves as the students' official radio station; the station also attracts an audience in the immediately surrounding community due to its eclectic and free-form musical programming. WUTV is the university's closed-circuit television channel. The university's main student-run political publication is the Washington University Political Review (nicknamed "WUPR"), a self-described "multipartisan" monthly magazine. Washington University undergraduates publish two literary and art journals, The Eliot Review and Spires Intercollegiate Arts and Literary Magazine. A variety of other publications also serve the university community, ranging from in-house academic journals to glossy alumni magazines to WUnderground, campus' student-run satirical newspaper.
How many media outlets does Washington University support?

Answer: four


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Signal Hill is a hill which overlooks the city of St. John's. It is the location of Cabot Tower which was built in 1897 to commemorate the 400th anniversary of John Cabot's discovery of Newfoundland, and Queen Victoria's Diamond Jubilee. The first transatlantic wireless transmission was received here by Guglielmo Marconi on 12 December 1901. Today, Signal Hill is a National Historic Site of Canada and remains incredibly popular amongst tourists and locals alike; 97% of all tourists to St. John's visit Signal Hill. Amongst its popular attractions are the Signal Hill Tattoo, showcasing the Royal Newfoundland Regiment of foot, c. 1795, and the North Head Trail which grants an impressive view of the Atlantic Ocean and the surrounding coast.
 Who recieved the first transatlantic wireless transmission?
A: Guglielmo Marconi


Context and question: Himachal was one of the few states that had remained largely untouched by external customs, largely due to its difficult terrain. With the technological advancements the state has changed very rapidly. It is a multireligional, multicultural as well as multilingual state like other Indian states.

The caste communities residing in Himachal include the Khatri, Brahmins of the Hindu Faith and the Sikh Brahmin Caste Bhatra, Rajputs, Gujjars, Gaddis, Ghirth (choudhary), Kannets, Rathis and Kolis, Sood There are tribal populations in the state which mainly comprise Kinnars, Pangawals, Sulehria, and Lahaulis.The people Of Himachal Pradesh are very simple and live a traditional ´Pahari' lifestyle.
What are the common languages spoken?
Answer: Hindi, Pahari, Dogri, Mandeali Kangri, Mandyali, Gojri and Kinnauri


Question: Serotonin is a neuromodulator involved in regulation of mood and behavior. Development in the limbic system plays an important role in determining rewards and punishments and processing emotional experience and social information. Changes in the levels of the neurotransmitters dopamine and serotonin in the limbic system make adolescents more emotional and more responsive to rewards and stress. The corresponding increase in emotional variability also can increase adolescents' vulnerability. The effect of serotonin is not limited to the limbic system: Several serotonin receptors have their gene expression change dramatically during adolescence, particularly in the human frontal and prefrontal cortex .
Is there an answer to this question: Which two neurotransmitters cause adolescents to be more emotional and more responsive to rewards and stresses?

Answer: dopamine and serotonin


Question: The Greeks of classical antiquity idealized their Mycenaean ancestors and the Mycenaean period as a glorious era of heroes, closeness of the gods and material wealth. The Homeric Epics (i.e. Iliad and Odyssey) were especially and generally accepted as part of the Greek past and it was not until the 19th century that scholars began to question Homer's historicity. As part of the Mycenaean heritage that survived, the names of the gods and goddesses of Mycenaean Greece (e.g. Zeus, Poseidon and Hades) became major figures of the Olympian Pantheon of later antiquity.
Is there an answer to this question: What two epics were written to honor Zeus?

Answer:
unanswerable
