I apologise, I should have been more careful

It was only when I read post #3 that this point was clear to me, i wasn't thinking this way earlier..

Yes this was the intended question , my instructor wrote it in class on the blackboard and then he just solved it, this was the diagram provided and the homework statement was all that was given. Nevertheless I should have added the assumptions which was never written down in the question but...

do you mean as in the weight component of block B along the inclined plane exceeds even the maximum static friction? this is before spring force starts developing due to block A ?...

But since we are increasing the mass gradually, aren't we sure that only at the maximum extension of the spring we will get a new spring force to check if it is sufficient enough to just move block B? wouldn't using kx=mg here give us more than the minimum mass?...

The spring is relaxed when the system is released from rest. Yes... Yes i do mean that, sorry for the wording. After reading post #3 i think i get it, the mass of block A increases gradually, so if we didn't get the amount of force required to move block B even after the spring goes till...

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static...

I obviously still have a long way to go to become like yourself and others on this site, but thanks:angel:

this was possibly the dumbest question i asked on here, at that time i had just started learning physics and had very wrong intuition/assumptions lol, i mean i was literally calling the "restoring force" reaction force as if action and reaction forces act on the same body o0). i also thought...

Oh i missed that sorry just noticed. Anyways thankyou for helping me understand it. ☺

Yes, since you specifically asked in post #2 about sunset so that's what I replied to..

The sun is physically on the lower right but we see it on the upper right right during sunset...its virtual image is what we see and in our pov it stays for longer..

The upper image of the sun on the right

Yes I can stil see the upper edge after it is geometrically lined up with the horizon. So like the day starts earlier and ends later for us observers? Hence the time interval is longer?

I honestly do not understand which one is referring to which one, the optical length states that the time interval between the instant when the top of the sun is just "visibly observed" above the horizon to the instant at which the top of the sun just disappears below the horizon. The sun that...
