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)

What is the power generated by a 45 kg person who walks up a flight of 12 stairs, each 30 cm high, in 12 s?
Free_Kalibri [48]
The total distance covered by the person is 12 times the height of each stair:
\Delta h=12 \cdot 30 cm=360 cm=3.60 m

The work done by the person to climb the stairs is equal to the increase in his gravitational potential energy:
W= \Delta U=mg \Delta h=(45 kg)(9.81 m/s^2)(3.60 m)=1589.2 J

And therefore, the power generated by the person in 12 s is the work done divided by the time taken:
P= \frac{W}{t}= \frac{1589.2 J}{12 s}=132.3 W

So, the correct answer is B.
