question:
In ferromagnetic materials, a version of this effect occurs in which the resultant resistivity predicted by this effect contains an additional zero-field term proportional to the magnetization. Arranging two solid-state elements which demonstrate this effect at right angles to each other and summing their output voltage to eliminate the noise is a typical way of producing a magnetic field sensor using this effect. This effect is derived by noting that the current crossed with the magnetic field creates a transverse current, which results in a potential difference. For ten points, identify this classical effect in which charge flowing across a transverse magnetic field results in an electric field component orthogonal to both the current and the magnetic field, often used to measure the sign of charge carriers.
answer:
Science


question:
When these devices exploit their voltage-dependent variable capacitance they are known as varactors. Barring the creation of local hot spots, a non-destructive avalanche current is produced by electron-hole pair propagation when the electric field within the (*) depletion region of these devices reaches a critical value. Majority carriers exist in an energy state greater than the Fermi energy in the Schottky barrier variety and those that operate in reverse breakdown are named after Zener. For 10 pointsname these devices that allow current to pass in only one direction.
answer:
Science


question:
Historical verification of this event was provided by Jean Froissart and Jean de Vanette. The leader of this event was invited to truce talks in Mello, but upon arriving was seized and immediately decapitated. One cause of this event was the inability of the French government to stop the plundering of northern France by unpaid English, German, and Spanish mercenaries after the completion of the Hundred Years War, but the main cause were the heavy taxes and payments of compensation for the war that the nobles levied on the peasants. For ten points, name this French revolt of 1358 whose name is now synonymous with peasant uprisings.
