A simple experiment to measure the speed of sound doesn't involve a stopwatch. You can fill up along tube with water and put a t
Serhud [2]

Answer:

Explanation:

In order to answer this problem you have to know the depth of the column, we say R, this information is important because allows you to compute some harmonic of the tube. With this information you can compute the depth of the colum of air, by taking tino account that the new depth is R-L.

To find the fundamental mode you use:

f_n=\frac{nv_s}{4L}

n: mode of the sound

vs: sound speed

L: length of the column of air in the tube.

A) The fundamental mode id obtained for n=1:

f_1=\frac{v_s}{4L}

B) For the 3rd harmonic you have:

f_3=\frac{3v_s}{4L}

C) For the 2nd harmonic:

f_2=\frac{2v_s}{4L}

Scorpion4ik [409]

The accelerations will be the same because the acceleration of each rock is caused only by gravity, which accelerates objects the same amount no matter what the velocity is.

Damm [24]

Answer:

Nuestro mejor amigo escuchará la música más rápido a una temperatura de 36 ºC (309.15 K)

Explanation:

Supongase que el aire se comporta como un gas ideal y que experimenta un proceso adiabático, entonces la velocidad del sonido (v), medida en metros por segundo, queda traducida en la siguiente fórmula:

v = \sqrt{\frac{\gamma \cdot R_{u}\cdot T}{M} } (1)

Donde:

\gamma - Coeficiente de dilatación térmica, sin unidad.

R_{u} - Coeficiente universal de los gases ideales, medido en kilogramo-metros cuadrados por mol-Kelvin-segundo cuadrado.

T - Temperatura, medida en Kelvin.

M - Masa molar, medida en kilogramos por mol.

Como se puede ver, la velocidad del sonido es directamente proporcional a la raíz cuadrada de la temperatura. Por tanto, nuestro mejor amigo escuchará la música más rápido a una temperatura de 36 ºC (309.15 K)
