Suppose that mercury rotates on its axis once every days. the equator lies on a circle with a radius of miles. (a) find the angular speed of a point on its equator in radians per year ( days). (b) find the linear speed of a point on the equator in miles per year. do not round any intermediate computations, and round your answer to the nearest whole number.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
