QUES: Found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives, electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as from the power grid, inverters or generators. Small motors may be found in electric watches. General-purpose motors with highly standardized dimensions and characteristics provide convenient mechanical power for industrial use. The largest of electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors may be classified by electric power source type, internal construction, application, type of motion output, and so on.

What is the main example of a RC power source?

QUES: Originally, Dell did not emphasize the consumer market, due to the higher costs and unacceptably low profit margins in selling to individuals and households; this changed when the company's Internet site took off in 1996 and 1997. While the industry's average selling price to individuals was going down, Dell's was going up, as second- and third-time computer buyers who wanted powerful computers with multiple features and did not need much technical support were choosing Dell. Dell found an opportunity among PC-savvy individuals who liked the convenience of buying direct, customizing their PC to their means, and having it delivered in days. In early 1997, Dell created an internal sales and marketing group dedicated to serving the home market and introduced a product line designed especially for individual users.

When did Dell end their internal marketing group?
What is the answer?
ANS:
unanswerable
