Problem: Capacitor:

where a single prime denotes the real part and a double prime the imaginary part, Z(ω) is the complex impedance with the dielectric present, Ccmplx(ω) is the so-called complex capacitance with the dielectric present, and C0 is the capacitance without the dielectric. (Measurement "without the dielectric" in principle means measurement in free space, an unattainable goal inasmuch as even the quantum vacuum is predicted to exhibit nonideal behavior, such as dichroism. For practical purposes, when measurement errors are taken into account, often a measurement in terrestrial vacuum, or simply a calculation of C0, is sufficiently accurate.)

How is the non-complex impedance with dielectric represented mathematically?

A: unanswerable


Problem: Alloying copper with tin to make bronze was first practiced about 4000 years after the discovery of copper smelting, and about 2000 years after "natural bronze" had come into general use[citation needed]. Bronze artifacts from the Vinča culture date to 4500 BC. Sumerian and Egyptian artifacts of copper and bronze alloys date to 3000 BC. The Bronze Age began in Southeastern Europe around 3700–3300 BC, in Northwestern Europe about 2500 BC. It ended with the beginning of the Iron Age, 2000–1000 BC in the Near East, 600 BC in Northern Europe. The transition between the Neolithic period and the Bronze Age was formerly termed the Chalcolithic period (copper-stone), with copper tools being used with stone tools. This term has gradually fallen out of favor because in some parts of the world the Chalcolithic and Neolithic are coterminous at both ends. Brass, an alloy of copper and zinc, is of much more recent origin. It was known to the Greeks, but became a significant supplement to bronze during the Roman Empire.
When did the Bronze Age began in Southeastern Europe?

Answer: 3700–3300 BC


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Although all these different Shia tariqahs belong to the Shia group (as opposed to the Sunni group) in Islam, there are major doctrinal differences between the main Shia tariqahs. After that there is the complete doctrinal break between all the different Shia tariqahs whose last Imams have gone into Occultation and the Shia Nizari Ismailis who deny the very concept of Occultation. The Shia Nizari Ismailis by definition have to have a present and living Imam until the end of time.[citation needed] Thus if any living Nizari Ismaili Imam fails to leave behind a successor after him then the Nizari Ismailism’s cardinal principle would be broken and it’s very raison d'être would come to an end.
What has happened to some of the Shia tariqahs last Imams?
A: Occultation


Context and question: In South Africa, the period of colonization resulted in many unions and marriages between European men and African women from various tribes, resulting in mixed-race children. As the Europeans acquired territory and imposed rule over the Africans, they generally pushed mixed-race and Africans into second-class status. During the first half of the 20th century, the Afrikaaner-dominated government classified the population according to four main racial groups: Black, White, Asian (mostly Indian), and Coloured. The Coloured group included people of mixed Bantu, Khoisan, and European descent (with some Malay ancestry, especially in the Western Cape). The Coloured definition occupied an intermediary political position between the Black and White definitions in South Africa. It imposed a system of legal racial segregation, a complex of laws known as apartheid.
What was a result of these marriages?
Answer: mixed-race children


Question: Immanuel Kant (1724–1804) has formulated an individualist definition of "enlightenment" similar to the concept of bildung: "Enlightenment is man's emergence from his self-incurred immaturity." He argued that this immaturity comes not from a lack of understanding, but from a lack of courage to think independently. Against this intellectual cowardice, Kant urged: Sapere aude, "Dare to be wise!" In reaction to Kant, German scholars such as Johann Gottfried Herder (1744–1803) argued that human creativity, which necessarily takes unpredictable and highly diverse forms, is as important as human rationality. Moreover, Herder proposed a collective form of bildung: "For Herder, Bildung was the totality of experiences that provide a coherent identity, and sense of common destiny, to a people."
Is there an answer to this question: Who said the following statement? "Enlightenment is man's emergence from his self-incurred immaturity".

Answer: Immanuel Kant


Question: Humanists reacted against this utilitarian approach and the narrow pedantry associated with it. They sought to create a citizenry (frequently including women) able to speak and write with eloquence and clarity and thus capable of engaging the civic life of their communities and persuading others to virtuous and prudent actions. This was to be accomplished through the study of the studia humanitatis, today known as the humanities: grammar, rhetoric, history, poetry and moral philosophy. As a program to revive the cultural – and particularly the literary – legacy and moral philosophy of classical antiquity, Humanism was a pervasive cultural mode and not the program of a few isolated geniuses like Rabelais or Erasmus as is still sometimes popularly believed.
Is there an answer to this question: What was it about the utilitatian beliefs that humanism believers did not like?

Answer:
narrow pedantry
