Una ambulancia se aleja de una persona en línea recta a razón de 30 m/s. Si la sirena está funcionando con una frecuencia de 360 Hz, ¿con qué frecuencia percibe la persona
el sonido de la sirena?

Explanation:

Use Doppler effect equation:

The Doppler effect is a physical phenomenon where an apparent change in wave frequency is presented by a sound source with respect to its observer when that same source is in motion. The general equation is given by:

Since the problem don't give us aditional information let's assume:

Which is the speed of sound in air.

And using the information provided by the problem:

The frequency perceived by the person is 331.046Hz

Translation:

Usa la ecuación del Efecto Doppler:

El efecto Doppler es un fenómeno físico en el que una fuente de sonido presenta un cambio aparente en la frecuencia de onda con respecto a su observador cuando esa misma fuente está en movimiento. La ecuación general viene dada por:

Como el problema no nos da información adicional, supongamos que:

La cuál es la velocidad del sonido en el aire.

Y utilizando la información proporcionada por el problema:

La frecuencia percibida por la persona es 331.046Hz

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
