Una ambulancia se desplaza por la calle a 34 m/s emitiendo un estruendoso sonido de sirena a 304 Hz, Si usted se ALEJA de la amb
Alik [6]

Answer:

f = 295.06 Hz

Explanation:

Este es un típico ejercicio de efecto doppler donde tenemos una fuente emisora de una frecuencia.

En este caso, vemos una ambulancia que se está desplazando a cierta velocidad emitiendo una frecuencia particular. Un observador que está en la calle decide alejarse, corriendo a una velocidad, que obviamente es menor que la de la ambulancia, pero el caso es que se está alejando de la fuente emisora del sonido, en este caso de la ambulancia.

Como se están alejando, podemos usar la siguiente expresión:

f = (v - v₀ / v) * f₀

Donde:

f: frecuencia percibida por la persona.

v: velocidad de la ambulancia

v₀: velocidad de la persona

f₀: frecuencia emitida por la ambulancia.

Teniendo todos esos valores, solo debemos reemplazar en la expresión:

f = (34 - 1 / 34) * 304

f = (33/34) * 304

<h2>f = 295.06 Hz</h2>

Espero te ayude
