Football practice got cancelled so I decided to be productive and do relative velocity. It did not go well. Here's the problem. Train A is 100 m long, train B is 150 m long, on parallel tracks. a They move in opposite di
Photoelectric effect, and my brain says: brighter light = more energy = faster electrons. But NCERT says the stopping potential depends on the frequency, not on intensity, while the photocurrent depends on intensity. Why
I made a small list of cases but I think two of them are wrong.
Most marks lost in mechanics come from a short list of repeat traps. Here is the list, with a quick fix for each.
Sorry, 1 AM, can't sleep, solid mechanics is eating me.
Dimensions, limiting cases and symmetry. Three boring checks that catch more mistakes than rereading ever did.
The chapter is short but formula-heavy. Which derivations are worth knowing, and which results can simply be learned?
Second attempt, going back to basics and trying not to just mug formulas this time. Electrostatic Potential chapter. For an electric dipole, the potential at a point on the equatorial line is zero since V = \dfrac{p\cos\
Doing wave optics PYQ-style questions and this one keeps eating my marks. Q: Unpolarised light of intensity I 0 passes through two polaroids whose pass axes make an angle of 60°. What's the intensity of the emergent ligh
This is making me crazy, and I know it's a classic NEET concept so I can't skip it. The binding energy per nucleon curve rises steeply for light nuclei, peaks near iron A around 56 and then falls slowly for heavy nuclei.
I am studying alternating current from NCERT. I understand that household voltage is written as 220 V but the peak is about 311 V. I want to understand why. My teacher said rms value comes from the average of \sin^2 bein
Revising Motion in a Plane from the start for my drop year plan week 2, Physics block . I made a template for each topic with "formula / common error / one solved example" and the last box for this topic is empty because
