The (x – t) graph of a particle undergoing simple harmonic motion is shown below. The acceleration of the particle at t=4/3 s is A particle executes SHM with a time period of 16s. At time t=2s its velocity is 4 ms^−1. The amplitude of motion in metre is? the particle crosses the mean position [...]

Two small loudspeakers A, B (1 m apart) are connected to the same oscillator so that both emit sound waves of frequency 1700 Hz in phase. A sensitive detector, moving parallel B (1 m apart) are connected to the same oscillator so that both emit sound waves of frequency 1700 Hz in phase. A sensitive [...]

Two identical sinusoidal waves with wavelengths of 3.00 m travel in the same direction at a speed of 2.00 m/s. The second wave originates from the same point as the first, but but Two identical sinusoidal waves with wavelengths of 3.00 m travel in the same direction at a speed of 2.00 m/s. The second [...]

A and B are two point sources of sound (of same frequency) and are kept at a separation. At a point P, the intensity of sound is observed to be I0 when only source A is put on. A and B are two point sources of sound (of same frequency) and are kept at a [...]
