Homework Statement http://img114.imageshack.us/img114/3643/acidspicem4.th.jpg http://g.imageshack.us/thpix.php My book says that if I attach an electron-donating group to an acid, it would decrease the acidity of that acid because the electrons would cause the already negative ion to...

Hi Stephan Hoyer. I searched more on what you explained on the internet. Just curious, did you learn that stuff in a general physics course like Electricity and Magnetism? Up to this point in my study (not much, just to electromagnetic waves now), I did not see any mention of space time...

Hi rbj. Thanks for answering my question. Frankly, I don't really understand it. But it seems like I am not the only one. I searched around and found a paper written probably by some graduate student who seem convinced that electric field and magnetic field travel 90 degrees out of phase in...

Hi. All the books I read depict the electric fields and magnetic fields in electromagnetic waves as being in phase - meaning they reach their max or their min at the same time. The books also say that the changing electric field creates magnetic field and changing magnetic field creates...

Based on the capacitance formula for a parallel-plate capacitor: ( C=EoA/d ), capacitance would equal 0 as distance between the plates approaches infinity. That means the plates would not hold any charges when they are connected to a battery if the plates are really far away from each other...

Thanks vanesche. Actually, I did think about capacity when I wrote the questions. I know that the closer the positive and negative plates are in a capacitor, the more charges they can hold given a certain potential difference. So that means that it takes the negative charges nearby to keep...

Hi. If a conductor (A) touches another highly charged conductor (B) such as one on the Van De Graaff generator, then I move conductor A via a string away from conductor B. Does conductor A retain the charges that it had gained when it touched the highly charged conductor? If conductor A...
