Work, Energy and Power. I made a table of "who does positive / negative / zero work" and several rows don't feel right to me. W = \vec F\cdot\vec d = Fd\cos\theta . I get: - Lifting a book at constant speed by h : work d
Study-planner girl with a doubt that doesn't fit into a planner. 😅 De Broglie: \lambda = h/p . For an electron accelerated through V volts, I know \lambda = \dfrac{1.227}{\sqrt{V}} nm. For V = 54 this gives 0.167 nm, and
One wrong sign flips real to virtual and magnified to diminished. Here is a single convention, one routine, and two worked examples.
I like having a clean template for every type of question, and electrochemistry is the only chapter where I can't make one. Let me show where my template breaks. Given: \text{Fe}^{3+} + e^- \to \text{Fe}^{2+}\quad E^\cir
Re-reading feels like progress but rarely builds recall. Here is how the team and a few desks suggest turning NCERT lines into something you can actually say without looking.
A tin box, a ₹50 note and a boring table that changed how I look at money.
A very nerdy experiment, a very small football, and a rule about never touching your phone at half time.
No car, no resort, no plan B. What we spent, what went wrong, and why I would do it again tomorrow.

A tired, honest, and (I hope) slightly useful letter to anyone opening their result for the second or third time.
Sorry for the 1 am post, I can't sleep and this question is stuck in my head sleep hygiene, I know, I know 😅 . I'm trying to track "n" chromosome number and "C" DNA amount for a human diploid cell 2n = 46, DNA content 2C
It's 1 am and I can't sleep so might as well ask this here. I keep going in circles with transcription. Part 1: strands. DNA template strand is 3'-ATGCATGCA-5'. I wrote the mRNA as 5'-UACGUACGU-3' but my guide key says t
