AI Thread Summary
The discussion centers on a calculation error in determining equivalent resistance, where one participant consistently arrives at 45.3 ohms instead of the correct 25.6 ohms. The resolution requires sharing intermediate steps to identify the mistake. Another participant emphasizes the importance of carefully distinguishing between series and parallel components in the problem. Ultimately, the original poster acknowledges a lack of common sense in their approach. The conversation highlights the significance of methodical problem-solving in physics calculations.

Can't tell where your mistake is unless you post your intermediate steps that lead you to a (false) answer of 45.3 ohms, but I did it my self and I found it to be 25.6 ohms indeed (25.555 to be more precise).

Yes I figured it out I wasn't using my common sense, thank youDelta2 said:

Not exactly common sense, but it is kind of easy problem if you carefully identify the components in series and the components in parallel.danielsmith123123 said:
Kindly see the attached pdf. My attempt to solve it, is in it.
I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction.
I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance)
My thoughts for the first case , one of them must be 12 volt while the other is 0
The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h.
So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
