Areaction taking place in a container with a piston-cylinder assembly absorbs 4850. j of heat and has a change in the internal energy of 1618.5 j. what is the final volume of the container if the reaction occurs under a constant external pressure of 5.5 atm and the initial volume of the container is 10.5 l?

The law of conservation of energy states that energy cannot be created or , energy can be from one substance to another. the first blank is ' destroyed ' and for the second blank is ' transferred '

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) =_
