I'm guessing you mean second finger - sometimes called the middle finger. (Maybe you don't want to appear rude!) It sounds right...

You could: a) State that you believe the question posed can’t be answered and briefly explain why. b) Propose a revision to make...

@NTesla, I (very nervously!) suggest that the AI answer is correct. Friction here, apart from the lowest point, always acts uphill...

It integrates to T.

@TensorCalculus, there may be timetabling clashes with a large number of concurrent subjects at AS/A2. It may be worth consulting...

EDIT. Aha. I see @haruspex has replied. But since I've already drafted the following, I'll post it. There are a set of surfaces having...

For future reference: Please provide the full statement of the problem exactly as given to you including any diagrams. If the answer is...

It’s possible that there is a mistake with the question’s wording (Post #1) and a mistake in the diagram (Post #9). If the viewer's eye...

I still fail to see how it could appear to be less than the true height when viewed from the denser medium.

I believe the author intends for the observer to be looking down into the water from above the water. There is enough information...

I understand. Thank you very much for the help and explanation DaveE, nasu, Steve4Physics

Say we have a transverse wave, moving in the +x direction, along a string. There are 2 very different types of graph and it’s easy to...

Wouldn’t that make the height seem greater?

My wife's work had a team building exercise one year where they were supposed to build miniature soap box derby style gravity cars and...

I do not disagree with this at all. If we are working with absolute pressures and ignoring surface tension then water pressure is always...
