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 48.0 ω resistor. you look at the rc circuit and see that the resistance is 40.0 ω. you combine the new resistor with the old to extend the half-life of the circuit. determine the new half-life (in s).

Explanation:

the half life of the given circuit is given by

where [/tex]\tau = RC[/tex]

Given

resistance in the circuit is 40 ohm and to extend the half cycle we added new resister of 48 ohm. the net resitance is 40+48 = 88 ohms

now the new half life is

Divide equation 2 by 1

putting all value we get new half life

answer:

explanation:

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.
