The resistance of a conductor is inversely proportional to its MCQ with Answer and Explanation

Explanation:
Sublimation: solid → gas. Example: dry ice (CO₂), camphor. Deposition is reverse (gas → solid). Melting solid → liquid, evaporation liquid → gas.

Explanation:
Work = force × displacement in direction of force. Displacement zero, so work zero. Physiology work is done internally, but physics work zero.

Explanation:
Viscosity η = Force/(Area × velocity gradient). Force [MLT⁻²], area [L²], velocity gradient [T⁻¹]. So η = [MLT⁻²]/([L²][T⁻¹]) = [ML⁻¹T⁻¹]. Often asked.
