Maxwell's Distribution Law (Thermal Physics)

Click For Summary
The discussion focuses on verifying solutions to two questions related to Maxwell's Distribution Law in thermal physics. The original poster has shared their attempted solutions but acknowledges that the images were uploaded in the wrong order. Key feedback emphasizes the need to express distributions in momentum space rather than velocity terms. Additionally, suggestions are made for improving the clarity and organization of the answers to facilitate better responses. The poster expresses gratitude for the advice and plans to repost with improved formatting.

Homework Statement
Please find the photo attached, titled 'Questions'.
Relevant Equations
dNv= 4πN (m/2πkBT)^(3/2) v^2 exp {-(mv^2)/2kBT}dv
There are two questions in the photo.

I have attempted the solution (attached below) and I would be highly obliged if someone would verify the same.

Edit- Sorry the images of the solution have uploaded in the wrong order. 5th and 1st Image comprise of both parts of Q1 while the remaining of Q2.

General observation: You are asked to provide distributions in momentum space. This means you should write these as ##f(p_x)## and ##f(p)## with no ##v_x## or ##v## on the right-hand side of the equation.

Personal observation: You might get more responses if your answers were more legible (i.e. in LaTeX) and better organized, perhaps by putting one answer immediately below the question it refers to. Viewers are more likely to respond if you show some consideration to them.

Thank you for your kind instructions. Will keep this in mind and repost the thread with the necessary formatting.
 
Thread 'Correct statement about size of wire to produce larger extension'
The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
