Both things that you addressed were things that I had already addressed in my original post and were not helpful. I stated that the problem was to be read from left to right, this is based on the label before and after. I also stated the convention for arrows in the second note of my post...

Hello, I assigned a work packet to my IB Physics students that guides them through how to make Feynman diagrams. This particular problem seems to have some issue, but perhaps it is something that myself and my class have all over looked. Note: At the beginning of the packet it states that some...

Ahaha I can't believe I've been misunderstanding this for so many years! Thank you all for pointing this out. I find solace in knowing that my understanding of the physics was correct, just not my understanding of the image.

It doesn't make sense to me that absorption spectra are (mostly) continuous. Here are my beliefs. Please tell me which piece/pieces is a/are misconception(s). 1) When light is absorbed, the energy is used to excite an electron to some discrete energy level. 2) To get to this discrete energy...

If you used an electronic balance which read 5.67, how would you write the reading with the uncertainty?

There is something I seriously don't understand about uncertainty. Suppose there is an electric balance that reads 5.67g The limit of reading is 0.01g The greatest possible error is half of the limit of reading and is thus 0.005g By this logic, and assuming the very best possible situation, I...

I apologize for not being clear enough with my question. In both scenarios, the stick will remain completely horizontal during the lift. It is objectively more difficult to lift a broomstick from the side than it is to lift it from the middle given that the broomstick remains completely...

If I lift a 1kg broom stick 1m when holding it from its center of mass, I will have done 9.8J of work and the broomstick would have gained 9.8J of potential energy. If I were instead to lift it from one end I would have to exert a much larger force due to torque. Lifting this same 1kg broomstick...

Interestingly enough, I just built this circuit and tried it out and I didn't receive the results you described. When I built the circuit that is shown in the video, which is the same circuit as yours without the parallel bulb in the primary, it worked as expected! When the secondary was a full...

So I think I get this now, the inductor will use most of the circuits voltage thus causing the red light to go out, but since the inductor is in parallel with the blue light, they will both be given the same amount of voltage, thus making the blue bulb bright. The high inductance of the inductor...

I read through this and it gave me a lot of the information I was missing. Thank you so much! This new understanding lead me to be able to do the research I needed in order to fill in some more of the missing pieces. I think I get it now: The problem I was having was that in my head, the...

I'm not understanding the points either of you two are making and I think its because I don't fundamentally understand what makes the primary different than just a simple AC circuit. I'll try to restate what I was originally trying to ask. Imagine this, I attach an AC power supply to a bulb...

I still don't see it.

I say "long term" because in the video the light doesn't just go out for a moment. It seems to permanently go out. What about the primary makes it need the help of the secondary? Is the circuit just designed that way?
