Bear in mind that this list is for people learning the Python
language and its standard library(as defined on python.org).
As such most of us will have no specialist domain knowledge
of your area.

It's not clear how x and y are related - which is what you are
seemingly trying to plot?
You define x in terms of v, k, T, and m
but you offer no clue what these are, where they come from etc.
Are they variables? constants? Are you trying a 3D plot of x/y
against one of these values?
Also I don't think ^(1/2) - a bitwise xor - is the python
expression you really want? I'm guessing you maybe mean
pow(0.5) or math.sqrt()?

linespace is not a builtin, is it part of the plotting
library you are using? I'm guessing it's the SciPy package
but I'm not sure?

You need to give us a lot more context.
If it is a SciPy problem there is a SciPy mailing list
where you may get more specialist readers who already
are familiar with your problem domain. But for this list
you need to assume we have almost zero knowledge of the
domain, only of the language.
