I'm currently working with some materials that have a high permittivity in order to improve image quality of MRI scanners but finding it hard to find a good book that explains the various effects that contribute to a material's permittivity/dielectric constant. Can anybody point me in a good...
Ah thanks, I guess I should've seen that from the expression for the impedance of the capacitor, I had just assumed that because there was a physical barrier separating both legs that no current would flow but there must be some induction between the plates. Is there anything from stopping the...
I am a physics student with very limited experience in electronics and I have been tasked with making an receive coil for use in an MRI machine. The design of an RF coil amounts to constructing to what essentially amounts to an LC resonator with a set resonance frequency. The design of my coil...

A Kaon (k0) decays into two charged pions (π+ & π-), what is the minimum momentum required for the kaon so that none of the pions move backwards (in the opposite direction of the kaon) in the laboratory frame.

Conservation of momentum...
As far as I'm aware because the question states that each person gets a maximum of 1 dollar the actual amount of money each person receives is counted in cents rather than dollars.
I am studying for a statistical physics exam and have been struggling with the statistic parts, especially calculating the number of microstates. I am starting to understand most questions but have no clue how to handle this one.
Homework Statement
We distribute a total of E dollars among a...
Wow yeah thanks, need to brush up on my more basic maths again I think. Thanks for the help from both of you! That question has been bugging me for a few weeks now =P.
That's what I assumed to be the case, but unless I am doing something wrong I end up with
\left(x-\frac{1}{2}\right)^2 - \left(y-\frac{1}{2}\right)^2 = 0
So the point is \left(\frac{1}{2},\frac{1}{2}\right)
Thanks for the quick reply though!

I sat my calculus exam at the end of june and of the questions on the paper required us to find the extreme values of the following equation:
g\left(x,y\right) = \left(x-1\right)\left(y-1\right)\left(x^{2} + y^{2} -2\right)
The Attempt at a Solution
So i get...
