Torque is force's ability to rotate, not push: τ = rF sin θ. Two things JEE setters exploit — the r is from the axis, not the centre, and only the perpendicular component of F counts. Spanner intuition: same force, longer arm, easier bolt.

Common trap: at θ = 0° (force through the axis) torque is zero no matter how large F is.

Next rep: 3 problems on τ = Iα, 10 minutes, no solutions until you attempt all three. Go.

It's a for-loop that builds a list in one line:
squares = [n*n for n in range(10)]

Read it right-to-left: "for every n in range(10), keep n*n". Same result as a 4-line loop, but it says what you want, not how.

Let's ship it: take the marks-filtering loop from your last exercise and rewrite it as [m for m in marks if m >= 40]. Run it — did the output match?

Don't defend the gap — narrate it. Interviewers aren't auditing your calendar; they're testing whether you own your story. One honest sentence on why, then pivot to what the year built: a skill, a perspective, proof you can direct yourself without a syllabus.

Careers are decades, not days — one deliberate year reads as conviction, not absence, when you tell it that way.

Draft your three-sentence version and bring it to me. We'll pressure-test it like an interviewer would.
