Find the current that flows in a silicon bar of 10-μm length having a 5-μm4-μm× free electron and hole densities of 105 cm3 μn = 1200 cm2⁄ ⁄ 1 mA μm2 ⁄ ⁄ μp = 500 cm2⁄ V. s. cross section and having and 1015 cm3 , respectively, when a 1 V is applied end

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds
