Acar going 24.5 m/s that is coming up to a red light and decelerates at a constant rate of -5.9 m/s2 until coming to a stop. 7. a mass on a spring whose height is given by the function h(t) 1.5sin (1.9t). 8. for questions 6 and 7 create individual plots of objects' position, velocity, and accel- eration as funetions of time. be sure to label your axest

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.)

6–43 a food department is kept at 2128c by a refrigerator in an environment at 308c. the total heat gain to the food department is estimated to be 3300 kj/h and the heat rejection in the condenser is 4800 kj/h. determine the power input to the compressor, in kw and the cop of the refrigerator.

What pressure difference is required between the ends of a 2.0-m-long, 1.0-mm-diameter horizontal tube for 40 c water to flow through it at an average speed of 4.0 m/s?
