QUES: In electric power distribution, capacitors are used for power factor correction. Such capacitors often come as three capacitors connected as a three phase load. Usually, the values of these capacitors are given not in farads but rather as a reactive power in volt-amperes reactive (var). The purpose is to counteract inductive loading from devices like electric motors and transmission lines to make the load appear to be mostly resistive. Individual motor or lamp loads may have capacitors for power factor correction, or larger sets of capacitors (usually with automatic switching devices) may be installed at a load center within a building or in a large utility substation.

How are capacitors used for for power factor correction prepared?
What is the answer?
ANS: as three capacitors connected as a three phase load
QUES: At its press conference at the 2007 Tokyo Game Show, Sony announced DualShock 3 (trademarked DUALSHOCK 3), a PlayStation 3 controller with the same function and design as Sixaxis, but with vibration capability included. Hands-on accounts describe the controller as being noticeably heavier than the standard Sixaxis controller and capable of vibration forces comparable to DualShock 2. It was released in Japan on November 11, 2007; in North America on April 5, 2008; in Australia on April 24, 2008; in New Zealand on May 9, 2008; in mainland Europe on July 2, 2008, and in the United Kingdom and Ireland on July 4, 2008.

What was the last country to be able to buy the new DualShock 3 in stores?
What is the answer?
ANS: unanswerable
QUES: Cotton is used to make a number of textile products. These include terrycloth for highly absorbent bath towels and robes; denim for blue jeans; cambric, popularly used in the manufacture of blue work shirts (from which we get the term "blue-collar"); and corduroy, seersucker, and cotton twill. Socks, underwear, and most T-shirts are made from cotton. Bed sheets often are made from cotton. Cotton also is used to make yarn used in crochet and knitting. Fabric also can be made from recycled or recovered cotton that otherwise would be thrown away during the spinning, weaving, or cutting process. While many fabrics are made completely of cotton, some materials blend cotton with other fibers, including rayon and synthetic fibers such as polyester. It can either be used in knitted or woven fabrics, as it can be blended with elastine to make a stretchier thread for knitted fabrics, and apparel such as stretch jeans.

For what can cotton yarn be used?
What is the answer?
ANS:
crochet and knitting
