A 40 kg box is being pushed on a horizontal surface. The coefficient of kinetic friction between the box and the ground is 0.25. What horizontal force must be exerted on the box for it to accelerate at 1.2 m/s^2?

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.)
