A sound source of frequency 450 Hz moves towards a stationary observer with speed 33 m/s. If the speed of sound is 330 m/s, the apparent frequency heard by the observer is:

A source of sound emits a frequency of 1000 Hz and moves towards a stationary observer at 30 m/s. The apparent frequency heard by the observer is: (speed of sound = 330 m/s)

A particle executes simple harmonic motion with amplitude A and angular frequency ω. The ratio of maximum speed to maximum acceleration is:

A particle executes SHM with amplitude A and time period T. The time taken by the particle to move from the mean position to a displacement of A/2 is:

A particle executes SHM with displacement x = A sin(ωt). The ratio of kinetic energy to total energy at displacement x = A/2 is:

A transverse wave is described by y = 0.05 sin(2π(0.5t − 0.01x)) where x and y are in meters and t in seconds. The wave speed is:
