SHM acceleration a = -ω²x. Maximum acceleration occurs at: MCQ with Answer and Explanation

SHM acceleration a = -ω²x. Maximum acceleration occurs at:
A. Neither
B. Mean position
C. Both positions
D. Extreme position
Answer: Option D
Solution (By JKExamLibrary)
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.

The process of change from solid directly to vapour is called
A. Freezing
B. Sublimation
C. Condensation
D. Melting

Correct Answer: Option B


Explanation:
Sublimation: solid → gas without liquid phase. Example: camphor, naphthalene balls, dry ice (solid CO₂). Deposition is reverse. Latent heat of sublimation involved.
