Maxwell Boltzmann Speed Distribution

AI Thread Summary
In the discussion about the Maxwell Boltzmann speed distribution, it is clarified that Vmost probable, Vaverage, and Vrms differ in three dimensions. When restricted to one dimension, these quantities do not equal each other. Vmost probable is identified as the peak of the distribution curve, while Vaverage is also suggested to align with this peak at V=0. The definition and calculation of Vrms, or root mean square velocity, are questioned, indicating a need for a mathematical formula for clarity. Understanding these distinctions is crucial for analyzing gas behavior in different dimensional contexts.

Homework Statement



The three quantities Vmost probable, Vaverage, and Vrms, are not the same for the Maxwell speed distribution in 3D. If you restrict the gas to only be one dimensional, are these three quantities equal to each other? Justify your answer with a short explanation.

Homework Equations


The Attempt at a Solution


The curve looks like gaussian curve. I know Vmostprobable is going to be the peak of the curve. And Vaverage would also be at the peak of the curve which is at V=0. I am not sure how to get Vrms

What's the definition of ##v_\text{rms}##?
 
Root mean square velocity
 
I was looking for perhaps a mathematical formula or some other indication that you know what those words mean.
 

Thread 'Rolling without slipping on a curved surface'

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...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

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...
