Aparallel-plate capacitor is constructed of two horizontal 15.6-cm-diameter circular plates. a 1.1 g plastic bead with a charge of -6.4 nc is suspended between the two plates by the force of the electric field between them. what is the charge on the positive (upper) plate?

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.)
