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.

Answers

Explanation:

Here is an outline of the argument for the urgent need to bring about a revolution in the aims and methods of academic inquiry, its full nature and structure, so that it takes the proper task of launching wisdom rather than just taking of knowledge.

The academy as it exists today is the product of two previous great intellectual revolutions.

The first was the scientific revolution of the 16th and 17th centuries, associated with Galileo, Kepler, Descartes, Boyle, Newton and many others, who in fact created modern science. A method was discovered for progressive knowledge acquisition, the popular empirical method of science.

The second revolution was the Enlightenment, especially the French Enlightenment, in the 18th century. Voltaire, Diderot, Condorcet and other philosophers had deeply important ideas that it may be possible to learn from scientific progress how to achieve the progress of society towards an enlightened world.

They not only came up with the idea: they did everything to bring the idea into their lives. They fought against dictatorial power, superstition, and injustice with weapons no more lethal than strife and ingenuity. They gave their support to the virtues of tolerance, openness to doubt, willingness to learn from criticism and from experience. With courage and vigor they worked hard to establish rationality and enlightenment in personal and social life.

What parts of this story are in preterite tense and what parts are in the imperfect tense

Carmen: Sandra, ¿qué onda? ¿Cómo pasaste las vacaciones? ​​

Sandra: Bueno, las vacaciones empezaron como siempre: ​​

todo el mundo estaba en la playa haciendo lo que le ​

gustaba, y yo estaba sola y aburrida. ​

Carmen: ¡Claro! ¡Como siempre! ​​

Sandra: Era como una película de terror. Estaba muy deprimida ​​

y hacía un calor agobiante cuando, sin esperarlo, vi otra ​

vez al chico del crucero. ​

Carmen: ¿Santiago? ¿El surfista? ¡Qué padre! ​​

Sandra: Sí... qué casualidad, ¿no? Lo interesante es que somos muy ​​

diferentes, pero nos gustaba hacer cosas juntos. Hicimos ​

un crucero, caminamos por la arena todos los días, ¡hasta ​

condujimos motos acuáticas! ​

Carmen: ¿Tú? ¡Imposible! ¡No lo creo! ​​

Sandra: ¡Ni yo! Pero nos divertimos mucho. Yo era una persona ​​

completamente diferente. Y mientras hacíamos todas estas ​

cosas, también hablábamos mucho... Creo que lo conozco ​

bien, aunque sólo estuve dos semanas en Baja California. ​

Carmen: ¿Y qué dijeron tus padres

andra: Pues, tuve que presentarlo a la familia entera... ¡qué horror! No ​​

puedo ni hablar de eso. ¡Eso sí! Santiago se divirtió con todos. ​

Carmen: ¿Y conociste a su familia? ​​

Sandra: Sí, sí, todos en la familia Aguirre fueron muy amables. Tienen ​​

una casa rodante y me invitaron a hacer un viaje con ellos a Los ​

Ángeles durante todo el mes de agosto. ​

Carmen: ¡No puedes ir en agosto! Ese mes viene mi primo Jorge a ​​

Monterrey y ya te dije que tienes que conocerlo. Es el amigo ​

perfecto para ti: el año pasado dirigió su propia película ​

independiente, y a la vez que hacía la película, escribía una novela ​

gráfica sobre sus experiencias... y una casa editorial la publicó ​

hace dos meses. ​

Sandra: ¡Ay!, no sé qué hacer. En mi vida nunca pasa nada, y cuando ​​

pasa, pasa todo junto.¡Realmente no sé qué hacer! ​

Carmen: Bueno, Sandra, recuerda que en realidad no te gusta mucho estar ​​

al aire libre ni hacer deportes. El surfista fue un buen amigo ​

para pasar las vacaciones, pero... ¿crees que tú y Santiago son ​

compatibles de verdad? ​

Sandra: Pues, no lo sé. Santiago fue muy bueno conmigo. Por otro lado, tu ​​

primo publicó una novela gráfica. ¡Lo mismo que me interesa a mí! ​

Carmen: Pues, amiga, tienes que decidirte pronto... ¡ya estamos en julio!
