Give you something to compare your results with. It's always nice to be able to see what changes have been made to the original, even if it's not technically the original (I know that was worded weird, I just don't know how else to explain it.) Hope this helped!
The answer is B. P waves.
I took the test and it was correct. I hope this helps!
Explanation:
Given that,
Two resistors 4.5 Ω and 2.3 Ω .
Potential difference = 30 V
When they are in series, the current through each resistor remains the same. First find the equivalent resistance.
R' = 4.5 + 2.3
= 6.8 Ω
Current,

So, the current through both lightbulb is the same i.e. 4.41 A.
When they are in parallel, the current divides.
Current flowing in 4.5 resistor,

Current flowing in 2.3 ohm resistor,

In parallel combination, are brighter than bulbs in series.
Answer:
It makes sense because on that the day the sun stops moving northward and starts moving southward
