Aclosely wound search coil has an area of 3.13 cm2, 135 turns, and a resistance of 61.1 ω. it is connected to a charge-measuring instrument whose resistance is 44.4 ω. when the coil is rotated quickly from a position parallel to a uniform magnetic field to one perpendicular to the field, the instrument indicates a charge of 3.44×10−5 c . what is the magnitude of the magnetic field?

Use the empirical rule. the mean speed of a sample of vehicles along a stretch of highway is 70 miles per hour, with a standard deviation of 4 miles per hour. estimate the percent of vehicles whose speeds are between 66 miles per hour and 74 miles per hour. (assume the data set has a bell-shaped distribution.)
