Brilliant !

Thank you ! Can you please explain a bit further about what is actually going on in the problem? Its rather hard to picture the problem for me.

P,V,T all change. It means that the only entity left in Maxwell's relations is S. So are you suggesting\DeltaS is a constant?

Since the questions says "If \Delta p is fairly small, " is it ok to consider p as a constant? Other variables \DeltaT and \DeltaV do change. I am rather confused. Thank you

Homework Statement This is an experiment done on solid at high pressure. If the pressure is increased by an amount \Deltap, this being done under condition where the sample is thermally insulated and at a sufficiently slow rate that the process can be regarded as quasi-static, what is the...

my question seems to be wrong plus it is logical only if B over the orbit is half the B at the orbit. thanks a bunch.

that looks like a right idea to me...I checked the question, it should be twice not half at the orbit and even if you got B~ r^2, how is it going to be half ;$, i am confused.

oh i messed up a little bit above, 1/2 mv^2 = 1/2 qvBr 2K.E. = qvBr

Homework Statement Electrons are held by a magnetic field B in circular orbit in a vacuum chamber. The electrons are acclerated by increasing the magnetic flux linking the orbit. Prove that the average magnetic field over the plane of the orbit must be twice the magnetic field at the orbit if...

for B = 0 since, del E = \muB * ml * B actually, I think I didn't write the whole question. So, I am sorry for that, the question was for what values of the orbital angular momentum is the Zeeman effect zero. So, my first answer is correct. thanks for the help =)

It depends on magnetic field (B).

Homework Statement When is Zeeman effect interaction 0? Homework Equations The Attempt at a Solution I was thinking that when l=0, then Zeeman effect interaction should be 0 because when l =0, we only have ml = 0. So, zeeman effect interaction should be zero. I haven't...

i haven't actually solved it yet, but i am pretty sure that i can figure it out. thanks.

Homework Statement Calculate potential function and the electric field for the region between two concentric cylinders, where V ( inner cylinder) = 0 at r = 0.015 m and V(outer cylinder) = 100 for r = 0.025 Homework Equations \Delta (square ) V = 0 The Attempt at a Solution so...

hey, I have attached a figure. I thought this might make your life a little bit easier...i think you have to calculate potential and then calculate E, otherwise it's going to be hard. I think the x and z components cancel each other. so, you will only have y component of electric field. good luck.
