Hey guys. I'd like to make a very quick question! Maxwell's Relations in thermodynamics help us calculate how quantities that we cannot directly measure change in respect to a parameter, by measuring how measurable quantities change in respect to another parameter. Now when it come to megnetic phenomena, what are the measurable and what are the immeasurable quantities.
in the area r<b there is the field that the insulator creates. In this area the conductor creates no field. But i still dont get it. You must have charge in the inner walls. Which should have effect right?
Suppose we have a spherical insulator charges with Q inside a spherical conducting shell charges with -2Q. Now why does the conductor creates zero field inside it.
Hey guys! Quick question. Is the intensity of the electrostatic field of a homogeneously electrically charged plate prerpendicular to it only when is has infinite dimensions? That's what i find.
Hey guys, i have a problem with inertial-non inertial frame of references. Relativity of motion tells us that we cannot tell if i am moving and you are still, if i am still and you are moving or we are both moving. The same applies to acceleration! The observer that is accelerating it a non inertial observer, right? So, is there an objectively non inertial observer? If so how do we know who is one?
I am reading the Feynman Lecture and it has some pretty basic stuff. I know the velocity is the derivative of position, so when i differentiate this pops up (i think).
Hey, got a question. If we integrate both parts of an acceleration equation ( a = bcosθ) then do we get a formula that gives us the speed of the body? ie (a = bsinθ)
@dmckee @alarge @ChrisWhite @KyleKanos @ACuriousMind So are there any advantages as far as job prospects are concerned to become a physicist than an engineer? They all get similar jobs anyway :/
