Areaction inside a cylindrical container with a movable piston causes the volume to change from 12.0 l to 18.0 l while the pressure outside the container remains constant at 0.975 atm. (the volume of a cylinder is v = πr 2h), where h is the height; 1 l atm = 101.325 j) a. what is the value in joules of the work w done during the reaction?

Which is special about a dc circuit ? a. it has both series and parallel components b. it has only series or only parallel components c. charge moves in a single direction d. charge moves back and forth quickly

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_
