QUES: AFSCs range from officer specialties such as pilot, combat systems officer, missile launch officer, intelligence officer, aircraft maintenance officer, judge advocate general (JAG), medical doctor, nurse or other fields, to various enlisted specialties. The latter range from flight combat operations such as a gunner, to working in a dining facility to ensure that members are properly fed. There are additional occupational fields such as computer specialties, mechanic specialties, enlisted aircrew, communication systems, cyberspace operations, avionics technicians, medical specialties, civil engineering, public affairs, hospitality, law, drug counseling, mail operations, security forces, and search and rescue specialties.
What is an example of an occupational field position in the USAF?

ANS: computer specialties

QUES: Oklahoma City is the principal city of the eight-county Oklahoma City Metropolitan Statistical Area in Central Oklahoma and is the state's largest urbanized area. Based on population rank, the metropolitan area was the 42nd largest in the nation as of 2012.
What place was Oklahoma cities population ranked in the nation in 2012?

ANS: 42nd

QUES: Infractions of the rules are punished with penalties, typically a loss of yardage of 5, 10 or 15 yards against the penalized team. Minor violations such as offside (a player from either side encroaching into scrimmage zone before the play starts) are penalized five yards, more serious penalties (such as holding) are penalized 10 yards, and severe violations of the rules (such as face-masking) are typically penalized 15 yards. Depending on the penalty, the penalty yardage may be assessed from the original line of scrimmage, from where the violation occurred (for example, for a pass interference infraction), or from where the ball ended after the play. Penalties on the offence may, or may not, result in a loss of down; penalties on the defence may result in a first down being automatically awarded to the offence. For particularly severe conduct, the game official(s) may eject players (ejected players may be substituted for), or in exceptional cases, declare the game over and award victory to one side or the other. Penalties do not affect the yard line which the offence must reach to gain a first down (unless the penalty results in a first down being awarded); if a penalty against the defence results in the first down yardage being attained, then the offence is awarded a first down.
What other than yardage is sometimes awarded the offence on a defensive penalty?

ANS: first down

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.
How can electrolytic capacitors be safely used after having been stored unused for a long time?

ANS:
by gradually applying the operating voltage
