QUES: Capacitors are connected in parallel with the power circuits of most electronic devices and larger systems (such as factories) to shunt away and conceal current fluctuations from the primary power source to provide a "clean" power supply for signal or control circuits. Audio equipment, for example, uses several capacitors in this way, to shunt away power line hum before it gets into the signal circuitry. The capacitors act as a local reserve for the DC power source, and bypass AC currents from the power supply. This is used in car audio applications, when a stiffening capacitor compensates for the inductance and resistance of the leads to the lead-acid car battery.

What do parallel capacitors do to fluctuating current in order to deliver "dirty" power for control circuits?

QUES: Part of the Haunted Mansion attraction at Disneyland in Anaheim, California, and Disneyland in Paris, France, takes place on an elevator. The "stretching room" on the ride is actually an elevator that travels downwards, giving access to a short underground tunnel which leads to the rest of the attraction. The elevator has no ceiling and its shaft is decorated to look like walls of a mansion. Because there is no roof, passengers are able to see the walls of the shaft by looking up, which gives the illusion of the room stretching.

 The Haunted Mansion at Disneyland in California and the one in Paris, France sharewhat attribute?
What is the answer?
ANS: takes place on an elevator
QUES: Since the mid-1990s, Melbourne has maintained significant population and employment growth. There has been substantial international investment in the city's industries and property market. Major inner-city urban renewal has occurred in areas such as Southbank, Port Melbourne, Melbourne Docklands and more recently, South Wharf. According to the Australian Bureau of Statistics, Melbourne sustained the highest population increase and economic growth rate of any Australian capital city in the three years ended June 2004. These factors have led to population growth and further suburban expansion through the 2000s.

How many years did Melbourne sustain the highest population increase and economic growth?
What is the answer?
ANS:
