Q: 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.

A: What is the largest rating of an electric motor?

Q: The consolidation of the "hot AC" format contrasted with the near-demise of most other AC formats: Beginning with the 2005-2007 economic downturn and eventual recession most stations went for the more chart-based CHR, along with the top 40, urban and even Latino formats. Diminishing physical record sales also proved a major blow to the AC genre.

A:
Along with the recession, what broad economic trend marked the decline of adult contemporary radio stations?
