An escalator carries you from one level to the next in an airport terminal. The upper level is 4.6 m above the lower level, and the length of the escalator is 7.4 m . Assume that your mass is 64 kg .
How much work does the up escalator do on you when you ride it from the lower level to the upper level?
How much work does the down escalator do on you when you ride it from the upper level to the lower level?

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.)
