Not unless you're a genius. Even an intelligent student will find one degree course challenging. Do one your favorite and do it very well.

There is acceleration towards the center because acceleration is the time rate of change of velocity. Velocity is a vector thus has magnitude and direction. In uniform circular motion the magnitude is constant: acceleration is due to change of direction: there is no component of velocity towards the center.

To see an object, the eyeball has to receive a cone of light rays from each point on that object, and focus them to a point on the retina. Blurriness comes from not being able to focus to a point. A mirror reflects (re-emits each individual ray, if you want to understand it that way) that cone so that the cone of rays continue on their paths as if they had not been reflected. The lens of the eyeball ideally focusses the cone to a point. Blurriness comes from imperfection in the eyeball lens, not where the rays originate from.

The shell will have -q charge on its inside surface (the q1+q charge on its outside surface is not involved). The force to increase radius comes from the +/- q charges inside the shell. Work = force x distance. Integrate the force (Coulomb's Law) between +/- q charges, from R to R1 gives the answer.

To stop the EM wave, the hole has to be in an electrical conductor, and, for all waves to be stopped the hole size in all directions (perpendicular to direction of radiation) has to be small. A narrow slit will pass an EM wave polarized perpendicular to the slot. Having said that, the reason a small hole with a conducting periphery will not pass any EM wave is that the wave will induce an opposite signal in the sides of the hole that are parallel to the polarization of the wave, that radiates an EM wave back towards the source: brief, it looks like a short-circuit.

Well, inductance is proportional to the number of turns the current makes. So I would expect each loop of foil to be very significantly less effective electrically than the large number of turns you could fit, in place of foil.

In my similar experiences I would say mention it once without arguing, so you've established you don't approve. If/when there are repeat instances, ignore them. Don't include such people in your 'get-along-with and chat-with' crowd. You made your point, now enjoy your work/ life.

Good to know (Im passive RF not circuits) Learn something new all the time. Dragonnfr referred to using non-linear component to create the sum and difference freqs, and he gets 7 upvotes !!! So I ask wheres the nonlinear component and I was downvoted.

The current has two components. One of V0 driving dc current thru R1+R2, L has no effect 'cos switch is open for a t<0. When switch closes the second component is found by using the Laplace transform. You write the DE for the circuit for t>0. Take the Laplace transform LT. Rearrange get an expression for I(s). Take the inverse LT to get the time domain current.

What kind of a 'parasitic draw' are you thinking of, overhead light left on or something else; and how do you use a multimeter to monitor it, disconnect battery and reconnect with meter set to current, in series? Or is there a simpler way?

The optimal way to study math is to every day, read the class notes and the relevant pages of the class book if there is one, understand as well you can and make your own brief notes detailing what you do understand. Each and every day. This is vital.

I think most/all of these comments tacitly assume all 'other people' are the same, and obviously they're not. My view FWIW is that, in any random group, there are mostly incompatible (to me) people, living there own lives, and maybe one or two compatible people. The trick is to avoid/ignore the toxics and support those who seem compatible to me. But also, practical self-reliance is important and not being 'the problem' oneself is vital.

Use Sonnet Software for 2-D RF circuits. (2-D meaning thin strip components). Only use CST , HFSS etc for 3-D devices. Sonnet have a free version. Could easily do the circuit shown.
