You are working in a lab where rc circuits are used to delay the initiation of a process. one particular experiment involves an rc circuit with a half-life of t1/2 = 3.00 s. your supervisor is concerned that the initiation of the process is occurring too soon and that the half-life needs to be extended. he asks you to change the resistance of the circuit to make the half-life longer. all you can find in the supply room is a single 39.0 ω resistor. you look at the rc circuit and see that the resistance is 34.0 ω. you combine the new resistor with the old to extend the half-life of the circuit. determine the new half-life (in s).
