FWIW, on the right-hand side you are adding quantities with different dimensions: ##v## has dimensions ##LT^{-1}##, ## \frac {dv}{dt}##...

@NTesla, maybe this is one source of your difficulty... That's not entirely correct. The horizontal section of the chain is...

Do you mean the equations from your Post #1? I can see them. Here's a copy, though LaTeX rendering may be a problem:

Yes, that's a valid point.

@NTesla, the last part of the question on the screenshot is missing. So here’s what (I believe) it should say: "... At a certain...

Assuming that's not rhetorical... You can’t. But there’s a possibility that a 60° angle was accidentally omitted from the question -...

1.15mm is a bit thin to call a rope! A ‘cord’ might be a better term. Nylon is stretchy, but this won’t affect the answer to the...

That’s one way of thinking about it. But I’m not convinced that is the intended interpretation. The ionisation energy of a molybdenum...

This is (IMO) a badly written question for another reason. The final state of the atom is ambiguous. Is it: a) missing only an...

Here’s a strategy to find the final state: 1) Calculate the amount of energy (A) needed to warm the ice to 0 deg.C. 2) Calculate the...

This post makes everything clear. Very high quality. All my doubts on this question got cleared! for a) I will take the direction of...

@palaphys, for an intuition, it helps to visualise flux lines. In the following diagram, the magnitude of the flux through the loop due...

The derivation of lens maker's formula already encapsulates the condition of refractive index of medium being different from that of the...

I'm not sure where you got this formula from. I've referred to more than 1 book, but couldn't find your version of the formula. I've...
