17 October 2026: heat, friction, magnetism and probability quiz

Convection — Convection carries energy through fluid movement. Conduction and radiation have different mechanisms.

Radiation — Radiation does not require a material medium, unlike conduction or convection.

Equal to the applied push — In the stated balanced situation, static friction adjusts to balance the push; it need not reach its limiting value.

Usually smaller — NCERT states that kinetic friction is usually less than the maximum static friction for the same surfaces.

North to south — Outside the magnet, the convention is north to south; inside, the closed curves continue from south to north.

Crossing would assign two field directions at one point — A compass would otherwise need to indicate two directions at the same point, contradicting the field’s unique local direction.

3/7 — Three of seven equally likely individual draws are white. The two colour names do not make their probabilities equal.

Elementary outcomes are equally likely — The counting formula assumes equally likely elementary outcomes, not merely a small number of named categories.

Odisha—Kalinga temple architecture — UNESCO identifies Konark as a thirteenth-century monument in Odisha and a major example of Kalinga temple architecture.

Surya — The World Heritage description identifies the temple’s chariot imagery with Surya, the Sun God.
