QUES: In 1578, Elizabeth I granted a patent to Humphrey Gilbert for discovery and overseas exploration. That year, Gilbert sailed for the West Indies with the intention of engaging in piracy and establishing a colony in North America, but the expedition was aborted before it had crossed the Atlantic. In 1583 he embarked on a second attempt, on this occasion to the island of Newfoundland whose harbour he formally claimed for England, although no settlers were left behind. Gilbert did not survive the return journey to England, and was succeeded by his half-brother, Walter Raleigh, who was granted his own patent by Elizabeth in 1584. Later that year, Raleigh founded the colony of Roanoke on the coast of present-day North Carolina, but lack of supplies caused the colony to fail.

What was Humphrey Gilbert's second destination?
What is the answer?
ANS: Newfoundland
QUES: The anti-clerical feeling was widespread, and Durango supported the initial reaction against the government at Mexico. In May 1832, Jose Urrea, a rising officer, supported the restoration of President Pedraza. On July 20, Governor Elorriaga was reinstated, and Baca along with the legislative minority were brought back to form a new legislature, which met on September 1. Chihuahua showed no desire to imitate the revolutionary movement and Urrea prepared to invade the state. Comandante-general J.J.Calvo threatened to retaliate, and a conflict seemed imminent. The entry of General Santa Anna into Mexico brought calm, as the leaders waited for clarity.

Who supported the restoration of President Pedraza?
What is the answer?
ANS: Jose Urrea
QUES: Electrolytic capacitors use an aluminum or tantalum plate with an oxide dielectric layer. The second electrode is a liquid electrolyte, connected to the circuit by another foil plate. Electrolytic capacitors offer very high capacitance but suffer from poor tolerances, high instability, gradual loss of capacitance especially when subjected to heat, and high leakage current. Poor quality capacitors may leak electrolyte, which is harmful to printed circuit boards. The conductivity of the electrolyte drops at low temperatures, which increases equivalent series resistance. While widely used for power-supply conditioning, poor high-frequency characteristics make them unsuitable for many applications. Electrolytic capacitors will self-degrade if unused for a period (around a year), and when full power is applied may short circuit, permanently damaging the capacitor and usually blowing a fuse or causing failure of rectifier diodes (for instance, in older equipment, arcing in rectifier tubes). They can be restored before use (and damage) by gradually applying the operating voltage, often done on antique vacuum tube equipment over a period of 30 minutes by using a variable transformer to supply AC power. Unfortunately, the use of this technique may be less satisfactory for some solid state equipment, which may be damaged by operation below its normal power range, requiring that the power supply first be isolated from the consuming circuits. Such remedies may not be applicable to modern high-frequency power supplies as these produce full output voltage even with reduced input.
