How is the speed of sound affected by density and temperature​

Answers

Answer 1

Answer:

If a material is more dense because its molecules are larger, it will transmit sound slower. Sound waves are made up of kinetic energy. It takes more energy to make large molecules vibrate than it does to make smaller molecules vibrate.

Answer 2
The speed varies with the medium employed (for example, sound waves move faster through water than through air), as well as with the properties of the medium, especially temperature.

The term is commonly used to refer specifically to the speed of sound in air.

At sea level, at a temperature of 21 degrees Celsius (70 degrees Fahrenheit) and under normal atmospheric conditions, the speed of sound is 344 m/s (1238 km/h or 770 mph).

The speed varies depending on atmospheric conditions; the most important factor is the temperature.

Humidity has little effect on the speed of sound, nor does air pressure by itself.

Air pressure has no effect at all in an ideal gas approximation.

This is because pressure and density both contribute to sound velocity equally, and in an ideal gas the two effects cancel out, leaving only the effect of temperature.

Sound usually travels more slowly with greater altitude, due to reduced temperature.

Por qué crees que es imposible mantener lo que se consigue con violencia?​

Answers

Es imposible mantener lo que se logra con la violencia, porque este es un acto que usa la fuerza física o algún tipo de intimidación moral contra algo o alguien.

La violencia nunca será la vía ideal para lograr el éxito o el avance social y profesional, ya que es necesario mantener la ética y la moral para el desarrollo de una sociedad.

Por tanto, todo acto de violencia debe ser combatido y castigado por la ley. Las personas deben expresarse a través de una comunicación ética que no infrinja los derechos y valores de los demás.

4. What do the children do in day six?

5. In the US, many children believe in Santa Claus. His ads the traditions of Santa Claus and the Three Kings similar? How are they different?

Answers

1. The text talks about the Sixth of January, one of the favorite days of the year for Hispanic children.

2. In this day, Melchor, Gaspar and Baltazar come riding on their camels to bring gifts to children.

3. The day before, families go to the city center to see a parade and Los Reyes Magos. Then children gather food for Los Reyes Magos and their camels.

4. The morning of the Sixth children wake up early to see what Los Reyes Magos brought them.

5. They are similar because like Santa, Los Reyes Magos bring gifts to children and children write them letters and leave them food. They are different because it is celebrated in another day, there are three people bringing gifts instead of one, they ride camels and not reindeers, Santa didn’t appear in the Bible while Los Reyes Magos, were three kings from eastern territories that brought gold, frankincense and myrrh to the baby Jesus.

Un automovilista se desplaza inicialmente con una velocidad de 10 m/s. Al pisar el acelerador alcanza una velocidad de 25 m/s en un tiempo de 6 segundos. ¿Cuál es la aceleración en este lapso?

Answers

Answer:

2,5 m / s-2

Explanation:

De la pregunta;

Velocidad inicial, u = 10 m / s

Velocidad final, v = 25 m / s

tiempo tomado, t = 6 segundos

Asi que,

a = v - u / t

a = 25 - 10/6

a = 15/6

a = 2,5 m / s-2
