A wave x meters long has a speed of y meters per second. The frequency of the wave is

1 answer:

6 0

The answer is B. y/x hertz.

Frequency of a wave is defined as the ratio between the speed and wavelength of the wave. The unit of frequency is hertz (Hz) which is also equivalent to s^-1 or "per second". Following the units of wavelength (m) and speed (m/s), it can also be inferred that frequency is equal to (m/s)/m or y/x.

What elements compose the stars and planets in the universe

Savatey [412]

Well hydrogen would be the main element, as a process called nuclear fusion with both helium and hydrogen atoms occurs within stars. And planets are the products of dead stars that have burned through their supplies of hydrogen, helium, and carbon. Planets are a product of this.

1) Si un mango cae a una velocidad de 75m/s y tarda 26 seg. en caer. ¿ Cuál habrá sido la velocidad con qué el mango llegó al su

Lyrx [107]

Answer:

El mango llega al suelo a una velocidad de 329.982 metros por segundo.

Explanation:

El mango experimenta un movimiento de caída libre, es decir, un movimiento uniformemente acelerado debido a la gravedad terrestre, despreciando los efectos de la viscosidad del aire y la rotación planetaria. Entonces, la velocidad final del mango, es decir, la velocidad con la que llega al suelo, se puede determinar mediante la siguiente fórmula cinemática:

$v = v_{o}+g\cdot t$ (1)
