El diagrama muestra la rotación de una paleta alrededor de "0" halle la velocidad (en m/s) del punto "A" cuando la velocidad en el punto "B" es de 6 m/s. OB= 2m y BA= 1m

Wo audio speakers are placed on a vertical rail. speaker a is placed at head-level while speaker b is place at some variable height, \delta yδy, above speaker a. both speakers receive simultaneous input from a sine-wave generator so the speakers each produce a pure sinusoidal sound wave with a wavelength of 0.531 meters. calculate the lowest height that speaker b can be placed above speaker a to produce a minimum of sound heard by person standing \delta x = 7.86δx=7.86 meters directly in front of speaker a.
