A60.0-kg woman stands at the western rim of a horizontal turntable having a moment of inertia of 500 kg ? m2 and a radius of 2.00 m. the turntable is initially at rest and is free to rotate about a frictionless, vertical axle through its center. the woman then starts walking around the rim clockwise (as viewed from above the system) at a constant speed of 1.50 m/s relative to the earth. consider the woman–turntable system as motion begins. (a) is the mechanical energy of the system constant? (b) is the momentum of the system constant? (c) is the angular momentum of the system constant? (d) in what direction and with what angular speed does the turntable rotate? (e) how much chemical energy does the woman’s body convert into mechanical energy of the woman–turntable system as the woman sets herself and the turntable into motion? serway, raymond a.. physics for scientists and engineers (p. 358). cengage textbook. kindle edition.

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.)
