1) with your pneumatic system, how do you think your results would have been affected if there had been a leak in the tubing? 2) given your observations for this investigation, would you rather ha a hydraulic braking system or a pneumatic braking system in your car. explain.

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) =_
