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:
Some of the figures in this painting are seemingly superfluous: Mercury stands at the far left, dispelling clouds from above trees laden with golden fruit. A Cupid on the wing aims his little bow, but is probably only there by grace of his mother Venus, above whom he hovers. The action takes place on the right. The West Wind, Zephyrus, pursues a virginal Chloris whom he will rape. Chloris is then shown transformed, bedecked with flowers, as the title character. For 10 points, name this Botticelli allegorical work.
answer:
Fine Arts
