I don’t see anything wrong with my steps. I think they are all logically sound. It’s more so that I’m paranoid and don’t want to lose points on homework for no reason really.
Hey! I had a question about this problem.
I did (1) Using
$$R_{0}=\rho\frac{l}{A}$$
For (2) I assume the question means that the radius increases by a meter.
So I used $$\bigtriangleup L = 2\pi (r_{E}+1) - l$$
and then I used that L to find the new R. Then I said $$\bigtriangleup R = R-R_{0}$$...
It’s from a practice midterm I was trying to solve. Sadly the professor does not provide solutions. I am assuming it is somewhat important if it is in a practice test.
Yeah so I was wondering what that would look like?
$$\oint \vec H \cdot d \vec l = NI$$
$$(l+s)H_{in} + sH_{gap} = NI$$
Is that valid? s is the gap length and l is the length of the original solenoid.
Then we use the same idea?
Hey, I was trying to figure out this problem. I got (a) using B = mu * NI/L
but I'm not sure how to start the part about the magnetic field in the gap after the solenoid is ripped in half with 1 cm gap.
Thanks for the help!
my reasoning would be that the extra 2kBT energy comes from the vibrational energy. And since vibrational energy can be quantized using h-bar*omega we can equate those two. However, I am not sure if the 2kBT comes only from vibrational or vibrational AND rotational energies. And also if the mass...
