full-wave rectifier with an l-section filter is used to supply a dc voltage of 250v at 100 ma to a resistive load. if the maximum permissible ripple factor is 2 percent determine a suitable combination of l and c which will yield the desired results. the fundamental power line frequency is 50 hz

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.)

In which of the following would the particles move most rapidly? a. ice at -20 °c b. water at 20 °c c. steam at 110 °c d. boiling water e. ice at 0 °c

It is really hard for me right know
