Problem: Capacitor:

Leakage is equivalent to a resistor in parallel with the capacitor. Constant exposure to heat can cause dielectric breakdown and excessive leakage, a problem often seen in older vacuum tube circuits, particularly where oiled paper and foil capacitors were used. In many vacuum tube circuits, interstage coupling capacitors are used to conduct a varying signal from the plate of one tube to the grid circuit of the next stage. A leaky capacitor can cause the grid circuit voltage to be raised from its normal bias setting, causing excessive current or signal distortion in the downstream tube. In power amplifiers this can cause the plates to glow red, or current limiting resistors to overheat, even fail. Similar considerations apply to component fabricated solid-state (transistor) amplifiers, but owing to lower heat production and the use of modern polyester dielectric barriers this once-common problem has become relatively rare.

With what value is a resistor in parallel with a capacitor equal to?
---
A: Leakage


Problem: Known as the fraternal birth order (FBO) effect, this theory has been backed up by strong evidence of its prenatal origin, although no evidence thus far has linked it to an exact prenatal mechanism. However, research suggests that this may be of immunological origin, caused by a maternal immune reaction against a substance crucial to male fetal development during pregnancy, which becomes increasingly likely after every male gestation. As a result of this immune effect, alterations in later-born males' prenatal development have been thought to occur. This process, known as the maternal immunization hypothesis (MIH), would begin when cells from a male fetus enter the mother's circulation during pregnancy or while giving birth. These Y-linked proteins would not be recognized in the mother's immune system because she is female, causing her to develop antibodies which would travel through the placental barrier into the fetal compartment. From here, the anti-male bodies would then cross the blood/brain barrier (BBB) of the developing fetal brain, altering sex-dimorphic brain structures relative to sexual orientation, causing the exposed son to be more attracted to men over women.
What does the FBO effect stand for?

Answer: fraternal birth order


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the 1890s, the recording formats of the earliest (toy) discs were mainly 12.5 cm (nominally five inches) in diameter; by the mid-1890s, the discs were usually 7 in (nominally 17.5 cm) in diameter. By 1910 the 10-inch (25.4 cm) record was by far the most popular standard, holding about three minutes of music or other entertainment on a side. From 1903 onwards, 12-inch records (30.5 cm) were also sold commercially, mostly of classical music or operatic selections, with four to five minutes of music per side. Victor, Brunswick and Columbia also issued 12-inch popular medleys, usually spotlighting a Broadway show score. However, other sizes did appear. Eight-inch discs with a 2-inch-diameter (51 mm) label became popular for about a decade in Britain, but they cannot be played in full on most modern record players because the tone arm cannot play far enough in toward the center without modification of the equipment.
What was the most popular sized disc by 1910?
A: 10-inch


Context and question: In October 2014, Beyoncé signed a deal to launch an activewear line of clothing with British fashion retailer Topshop. The 50-50 venture is called Parkwood Topshop Athletic Ltd and is scheduled to launch its first dance, fitness and sports ranges in autumn 2015. The line will launch in April 2016.
Beyonce and Topshops first products were to be sold in stores when?
Answer: autumn 2015


Question: Genes with a most recent common ancestor, and thus a shared evolutionary ancestry, are known as homologs. These genes appear either from gene duplication within an organism's genome, where they are known as paralogous genes, or are the result of divergence of the genes after a speciation event, where they are known as orthologous genes,:7.6 and often perform the same or similar functions in related organisms. It is often assumed that the functions of orthologous genes are more similar than those of paralogous genes, although the difference is minimal.
Is there an answer to this question: What are genes that result from divergence of the genes after a speciation event called?

Answer: orthologous genes


Question: 6th-century BCE pre-Socratic Greek philosophers Thales of Miletus and Xenophanes of Colophon were the first in the region to attempt to explain the world in terms of human reason rather than myth and tradition, thus can be said to be the first Greek humanists. Thales questioned the notion of anthropomorphic gods and Xenophanes refused to recognise the gods of his time and reserved the divine for the principle of unity in the universe. These Ionian Greeks were the first thinkers to assert that nature is available to be studied separately from the supernatural realm. Anaxagoras brought philosophy and the spirit of rational inquiry from Ionia to Athens. Pericles, the leader of Athens during the period of its greatest glory was an admirer of Anaxagoras. Other influential pre-Socratics or rational philosophers include Protagoras (like Anaxagoras a friend of Pericles), known for his famous dictum "man is the measure of all things" and Democritus, who proposed that matter was composed of atoms. Little of the written work of these early philosophers survives and they are known mainly from fragments and quotations in other writers, principally Plato and Aristotle. The historian Thucydides, noted for his scientific and rational approach to history, is also much admired by later humanists. In the 3rd century BCE, Epicurus became known for his concise phrasing of the problem of evil, lack of belief in the afterlife, and human-centred approaches to achieving eudaimonia. He was also the first Greek philosopher to admit women to his school as a rule.
Is there an answer to this question: Who first dismissed the idea that matter is made of atoms?

Answer:
unanswerable
