Intuitively, I would expect permittivity to increase with an increase in temperature. The relative permittivity is directly related to electric susceptibility, and I believe there are a number of publications that exist discussing the subject of the dependence on electric susceptibility of air...
There are three main methods of heat transfer - conduction, convection, and radiation. If you don't already know the difference between them, you can look them up to get an idea of how they work. Then think about which ones will be applicable to your experiment, and why. Are there any...
I have a question on clarifying some of the statements above...
Zz, you stated:
And yet phinds says:
If energy is a characteristic of things, and is nonsensical to talk about without the context of applying it to 'something', then how could the very early universe be described as 'hot'...
Thank you all for your help.
DrClaude, mfb - I had a strong suspicion most Penning traps in use were of the 'homemade' flavor, but thanks for confirming. The ion number density formula posted was helpful as well as the link, thank you both!
Does anyone know what the maximum capacity of a Penning Trap is or what this would depend on? Whether the capacity is measured in particles, mass, etc? I would presume that max capacity would depend on field strength of the trap, but if anyone could confirm this I'd be grateful.
A follow-up...

Hello all,
To my knowledge, there are still a lot of questions regarding the specifics of black hole formation. My question is in regards to formation time. I've read that the actual formation takes "less than a second" according to the equations. Does anyone know where time shows up in the...
I figured that much, but how much overlap is there? If there's only a slight amount of overlap is annihilation absolutely guaranteed? What about protonium - I have no idea what the distance is which the proton and antiproton orbit one another, but given that a protonium atom can exist for a...
Hello all. I had some questions on some of the specifics of matter-antimatter annihilation. I've tried looking this up but haven't had much success. If you guys know of any textbooks or journal articles that dig deep into the mechanics I'd be grateful if you'd post them.
Anyway, my basic...
Like Dale said, electrolytes conduct electricity via ions rather than electrons. In P-type semiconductors, positively charged 'holes' in the crystal lattice are the majority charge carriers rather than electrons. As far as I know, there are no solid materials where actual ions are the charge...
I don't think most people really worry too much about microwaves cooking their food. I don't know a lot about the subject but it seems to me like most of the 'harmful effects' are based on pseudoscience.
As mentioned above though that doesn't mean microwaves aren't dangerous...I wouldn't...
KVL is basically an expression of the principle of conservation of energy - wherever energy is consumed in a circuit, it had to be supplied somewhere else. If your power supply is providing you +4 V and you have four resistors, each causing a drop of 1 V, the total voltage when all summed...
Collect all the V+ terms on one side and all the V- terms on the other side of the equation. Then pull the V+ and V- terms out by clearing the fractions like jtbell said, and at that point all that is left to do is cross multiply and cancel your like terms. You'll need to pull out a negative...
The main difference I've noted between E. Physics and Physics is that the former involves more 'hands-on' work. Your course load may involve more programming, an emphasis on experimentation, or possibly even some work with machine tools or what I'm going to call device fabrication.
