A careless driver in a sedan with a mass of 1250 kg speeding at 24 m/s hits a slow moving truck with a mass of 16,250 kg moving at 10 m/s. The impact causes the truck to speed up to 12 m/s. a. Calculate the final velocity of the sedan after the collision b Is this an elastic or inelastic collision?

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.)

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 380j of energy to the room?
