A simple pendulum is taken to moon. Its time period MCQ with Answer and Explanation

Explanation:
h = ½ g t² = ½×10×16 = 80 m.

Explanation:
a ∝ -x; magnitude maximum when |x| maximum (extremes). At mean position x=0 ⇒ a=0. Velocity maximum at mean position. Memory aid: 'SHM: a max at extremes, v max at center'. Oscillation concept frequently tested in competitive exams to verify SHM characteristics understanding.

Explanation:
High c = absorbs/releases large heat with small ΔT. Stabilizes engine temperatures and organism body temperatures. Memory tip: 'High specific heat = thermal buffer; water moderates climate and physiology'. Property application frequently tested in competitive exams.
