question:
The electron dipole moment of this particle is at most three times ten to the negative 26th, and would violate CPT-symmetry if it is non-zero. This particle has a half-life of 881 seconds, and can break up into a proton, an electron and an electron antineutrino via beta decay. This particle is composed of one (*) up and two down quarks, and nuclear fission is initiated by the bombardment of this particle. The number of this particle dictates what isotope an atom is, and they have mass roughly equal to that of a proton. James Chadwick discovered, for ten points, what particle found in the nucleus, which, as its name suggests, has a net charge of zero
answer:
Science


question:
One member of this phylum, Strongylocentrotus purpuratus, is often used to study developmental processes, and another, Pisaster ochraceus, is an example of a keystone species. Most members of this phylum have pedicellariae that possess three jaws, and some have a chewing apparatus known as Aristotle's lantern. Members of class Asteroidea of this phylum have an ambulacral groove, and the madreporite is the entrance to their water vascular system that includes tube feet. FTP name this phylum whose "spiny skinned" members have radial symmetry and include sand dollars, sea urchins, and sea stars.
answer:
Social Science


question:
An early use of VP(R) structure can be found in the second motive in perhaps the most famous section in this composition, which there exists an F-sharp to B leap followed by a mildly surprising reversal to the half-note A. The melody of one section, which features a glass armonica, is played by the flute, backed by the strings, on top of glissando-like runs in the piano. The first piano plays a descending ten-on-one ostinato, while the second plays a six-on-one. Another section in this piece marked Allegro Pomposo utilizes a quotation from the Incidental Music of Mendelssohn's A Midsummer Night's Dream, while a double-bass plays a theme from "Dance of the Slyphs. " Yet another one instructs performers to "imitate the gaucheries of a novice," and thus suggests the fumbling tyro of scales by slowing down during tricky parts and speeding up at the end. The next movement borrows heavily from various sources including one of the composer's own works, Rossini's The Barber of Seville, and "Twinkle, Twinkle Little Star. " Forbidding this piece's performance during his lifetime, and including movements called "the Pianists," "Fossils" and "The Swan," for 10 points, name this "grand zoological fantasy" composed by Camille Saint-Saens.
