Problem: Capacitor:

Capacitors deviate from the ideal capacitor equation in a number of ways. Some of these, such as leakage current and parasitic effects are linear, or can be assumed to be linear, and can be dealt with by adding virtual components to the equivalent circuit of the capacitor. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effect is non-linear and normal (i.e., linear) network analysis cannot be used, the effect must be dealt with separately. There is yet another group, which may be linear but invalidate the assumption in the analysis that capacitance is a constant. Such an example is temperature dependence. Finally, combined parasitic effects such as inherent inductance, resistance, or dielectric losses can exhibit non-uniform behavior at variable frequencies of operation.

What causes the assumption of constant capacitance to fail even if the effect is linear in nature?

A: temperature dependence

Problem: Everton originally played in the southeast corner of Stanley Park, which was the site for the new Liverpool F.C. stadium, with the first official match taking place in 1879. In 1882, a man named J. Cruitt donated land at Priory Road which became the club's home before they moved to Anfield, which was Everton's home until 1892. At this time, a dispute of how the club was to be owned and run emerged with Anfield's owner and Everton's chairman, John Houlding. A dispute between Houlding and the club's committee over how the club should be run, led to Houlding attempting to gain full control of the club by registering the company, "Everton F.C. and Athletic Grounds Ltd". In response, Everton left Anfield for a new ground, Goodison Park, where the club have played ever since. Houlding attempted to take over Everton's name, colours, fixtures and league position, but was denied by The Football Association. Instead, Houlding formed a new club, Liverpool F.C.
Where did Everton FC relocate their games to in 1892?

Answer: Anfield

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Laws dating from 17th-century colonial America defined children of African slave mothers as taking the status of their mothers, and born into slavery regardless of the race or status of the father, under partus sequitur ventrem. The association of slavery with a "race" led to slavery as a racial caste. But, most families of free people of color formed in Virginia before the American Revolution were the descendants of unions between white women and African men, who frequently worked and lived together in the looser conditions of the early colonial period. While interracial marriage was later prohibited, white men frequently took sexual advantage of slave women, and numerous generations of multiracial children were born. By the late 1800s it had become common among African Americans to use passing to gain educational opportunities as did the first African-American graduate of Vassar College Anita Florence Hemmings. Some 19th-century categorization schemes defined people by proportion of African ancestry: a person whose parents were black and white was classified as mulatto, with one black grandparent and three white as quadroon, and with one black great-grandparent and the remainder white as octoroon. The latter categories remained within an overall black or colored category, but before the Civil War, in Virginia and some other states, a person of one-eighth or less black ancestry was legally white. Some members of these categories passed temporarily or permanently as white.
What makes a person mulatto?
A: parents were black and white

Context and question: Rainfall tends to be associated with Atlantic depressions or with convection. The Atlantic depressions are more vigorous in autumn and winter and most of the rain which falls in those seasons in the south-west is from this source. Average annual rainfall is around 980 millimetres (39 in). November to March have the highest mean wind speeds, with June to August having the lightest winds. The predominant wind direction is from the south-west.
From what direction do most of the winds blow on Plymouth?
Answer: south-west

Question: Feynman was elected a Foreign Member of the Royal Society (ForMemRS) in 1965. At this time in the early 1960s, Feynman exhausted himself by working on multiple major projects at the same time, including a request, while at Caltech, to "spruce up" the teaching of undergraduates. After three years devoted to the task, he produced a series of lectures that eventually became The Feynman Lectures on Physics. He wanted a picture of a drumhead sprinkled with powder to show the modes of vibration at the beginning of the book. Concerned over the connections to drugs and rock and roll that could be made from the image, the publishers changed the cover to plain red, though they included a picture of him playing drums in the foreword. The Feynman Lectures on Physics occupied two physicists, Robert B. Leighton and Matthew Sands, as part-time co-authors for several years. Even though the books were not adopted by most universities as textbooks, they continue to sell well because they provide a deep understanding of physics. Many of his lectures and miscellaneous talks were turned into other books, including The Character of Physical Law, QED: The Strange Theory of Light and Matter, Statistical Mechanics, Lectures on Gravitation, and the Feynman Lectures on Computation.
Is there an answer to this question: What was the name of the book Feynman wrote about the dark and nothingness?

Answer: unanswerable

QUES: Although a resonant antenna has a purely resistive feed-point impedance at a particular frequency, many (if not most) applications require using an antenna over a range of frequencies. An antenna's bandwidth specifies the range of frequencies over which its performance does not suffer due to a poor impedance match. Also in the case of a Yagi-Uda array, the use of the antenna very far away from its design frequency reduces the antenna's directivity, thus reducing the usable bandwidth regardless of impedance matching.

What type of antenna has impedance at a specific frequency?
What is the answer?
ANS:
resonant
