The graph between velocity and time for uniform acceleration is MCQ with Answer and Explanation

Explanation:
Planck's constant (h) has dimensions [ML²T⁻¹]. Angular momentum (L = mvr) has dimensions [M][LT⁻¹][L] = [ML²T⁻¹], matching exactly. Linear momentum is [MLT⁻¹], force is [MLT⁻²], and torque is [ML²T⁻²]. This dimensional equivalence is fundamental in quantum mechanics, linking wave-particle duality. Memory tip: Both represent 'action' quantities with identical dimensional structure. This concept frequently appears in competitive exams testing dimensional analysis skills.

Explanation:
1 AU ≈ 1.5 × 10⁸ km, average Earth-Sun distance.

Explanation:
Both reach same velocity v = √(2gh). Momentum = mass × v, so larger mass has greater momentum. KE different, but momentum differs.
