A 4m ladder weighing 250N is placed against a smooth vertical wall with it’s lower end 1.5m away from the wall. If the coefficient of friction between the ladder and the floor is 0.3 show that the ladder will remain in equilibrium

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.)
