The discussion clarifies that the symbol for micro (10^-6) is indeed represented by the Greek letter mu (μ). It points out that a common error occurs when the symbol for "proportional to" (∝) is mistakenly used instead of mu. In cases where TeX is unavailable or Greek letters are hard to type, some people substitute "u" for mu, such as using "uF" to denote microfarads. The conversation emphasizes the importance of using the correct symbol to avoid confusion. Accurate representation of scientific symbols is crucial for clear communication in technical contexts.

Homework Statement
I am confused about a notation highlighted shown below
Relevant Equations
C = Q/V
Can someone tell me what that means? I'm think it should be a mu.
If TeX is not available and Greek letters are difficult to type people sometimes use "u" instead (uF = ##\mathrm{\mu F}##). The "proportional to" (\propto, ##\propto##) is just the wrong symbol.
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 .
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...
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...
