You must forgive the heresy here at Physics Forums, where we call into question the infallability of the 12th Physics CBSE Board!

Your teacher is not infallible, so I'd reach out for clarification about the intended function and intended domain. Note that your...

The problem statement explicitly says ##M## is heavy enough to cause the masses to slide up the incline.

No, it is 0.01 m² = 100 cm². The exponent on the units is important: (0.1 m) X (0.1 m) = (0.1 X 0.1) (m X m) = 0.01 m.m = 0.01 m²; (10...

That was one of the great Oscar travesties. Ordinary People over The Elephant Man and Raging Bull?! Best director and best picture?!

The idea behind error propagation is to calculate the uncertainty in the result. Once you know the uncertainty, it tells you where to...

I suggest using the subjunctive here.

I think so too. There's some overlap, but there can still be a pretty big gap between the two majors. To properly prepare for physics...

Is PF a link-heavy site? In my brief look at a number of sites the other day, I noticed most sites don't underline every link, but they...

Kagi search results, on the other hand, do have underlined links. So do the sites for the New York Times, the LA Times, the Washington...

At the recent AAPT meeting, one of the updates to Glowscript/WebVPython is an improvement to better support accessibility. possibly...

Then I think it would help, as @robphy suggested above, if you could give us an example of a roadblock you're running into. Maybe you...

It is. My point was that if same spin meant both spin-up or both spin-down, it would correspond to only two of the triplet states and...

The same thought occurred to me; however, the solution explicitly lists all three of the triplet states and claims there's a threefold...
