The maximum displacement of a particle from mean position in SHM is called MCQ with Answer and Explanation

Explanation:
Each cycle produces one compression. 256 cycles, 256 compressions.

Explanation:
For equilibrium, net force = 0. If forces F₁ and F₂ are perpendicular, their vector sum R = √(F₁² + F₂²). The third force F₃ must balance R, so F₃ = -R, i.e., equal in magnitude and opposite in direction to the vector sum of F₁ and F₂. Memory aid: 'Equilibrium: vector sum of all forces = 0; third force closes the triangle'. This statics concept is frequently tested in competitive exams. Always use vector addition for force equilibrium; scalar sum is incorrect for non-collinear forces.

Explanation:
Frequency → pitch perception: higher frequency = higher pitch. Loudness depends on amplitude; timbre on waveform; speed on medium properties. Memory aid: 'Frequency = pitch; Amplitude = loudness'. Basic sound property question frequently tested to verify perceptual attribute associations in competitive exams.
