Total resistance=R1+ R2= 6Ω
Voltage=12v
Current =
Current= 2A
In a series circuit, equal current passes through every resistance.
Answer is option A
Explanation:
Below is an attachment containing the solution
-- In combination with 610 Hz, the beat frequency is 4 Hz.
So the unknown frequency is either (610+4) = 614 Hz
or else (610-4) = 606 Hz.
In combination with 605 Hz, the beat frequency will be
either (614-605) = 9 Hz or else (606-605) = 1 Hz.
-- In actuality, when combined with the 605 Hz, the beat
frequency is too high to count accurately. That must be
the 9 Hz rather than the 1 Hz.
So the unknown is (605+9) = 614 Hz.

If it’s wrong oh well because I just guest buh glad to help :)
Answer:
383.6 nJ
Explanation:
The energy stored in a capacitor is given by the formula:
where
C is the capacitance
V is the voltage applied
In this problem, we have
C = 14.8 nF is the capacitance of the capacitor
V = 7.2 V is the voltage
Substituting into the equation, we find:
