Hi everyone,
Really struggling to find anything on the internet to solve this problem. I really thought it would be an easy plug and chug equation..but I can't find it anywhere.
Basically, I was asked to find what the maximum and average energy of secondary electrons produced by 2 MeV...
Ok..I went back to this problem and still pretty stumped!
the given is ideal gas He at temp= 328K
This is a maxwell speed distribution problem.
we need to give 2 values of v that are in m/s for the equation 2F(v)=F(v*)
The maxwell speed distribution equation is given as
F(v) dv =...
v* = most probable speed
http://en.wikipedia.org/wiki/Maxwell%E2%80%93Boltzmann_distribution
I assume you use the maxwell speed distrtibution equation but for f(v) you but in f(v*) and solve the equation using v*. Then after you find the answer form f(v*) i guess you divide it by two to...
Again not really sure where to start here.
All the teacher told me was to use the Maxwell Speed Distrubution.
Any help will be greatly appreciated...I'm stuck.
Homework Statement
I have an equation with all known variables and I have the answer...I just can't figure out how they converted the variables and came about the answer.
The first equation is N/V = [2*pi*(2.315)/h^3][2*m*kT]^3/2
we have the known variables h (plank's constant)=...
Homework Statement
For an ideal gas He at T = 328 K find the two speeds v that satisfy the equation 2F(v) = F(v*).
m/s (lower speed)
m/s (higher speed)
Which of the two speeds you found is farther from v*?
the lower speed or the upper speed
Explain this result.

97.9747 = sinh (6.2737x10^9) How did they solve this??
Homework Statement
Just an equation that I don't understand how they calculated.
97.9747 = sinh(6.2737x109)...
6.2737x109 = 5.2779
how did they get the 5.2779 ??

Tunneling equation...have all the pieces, just can't figure out the calculation!
Hi,
I have an example from my book on Tunneling. All the parts of the equation are given, including the answer...put I keep comming up with the inccorect answer.
Maybe someone can clarify how to calculate...
Just curious on this method. I seemed to be getting caught up on the method here.
