Vikki [24]

Answer:

Ver explicacion

Explanation:

Según el modelo cinético, las moléculas de gas están en constante movimiento.

La energía cinética promedio de las moléculas del gas depende de la temperatura del gas y de la masa molar del gas.

Si los dos gases ocupan el mismo volumen a la misma temperatura, la energía cinética promedio ahora depende de la masa molar de los gases individuales. Cuanto menor sea la masa molar del gas, mayor será la velocidad media de las moléculas del gas.

El oxígeno gaseoso tiene una masa molar menor que el dióxido de carbono. Por lo tanto, el oxígeno tiene una velocidad molecular promedio mayor que el dióxido de carbono.

Answer:

c_2 = 6.04\ Km/s

Explanation:

given,

speed of wave, c₁ = 7.7 m/s

angle of incidence, i = 44°

angle of refraction, r = 33°

speed of wave in second medium.

using Snell's law

  n₁ sin i = n₂ sin r

\dfrac{n_1}{n_2}=\dfrac{sin\ r}{sin\ i}

\dfrac{n_1}{n_2}=\dfrac{sin\ 33^0}{sin\ 44^0}

\dfrac{n_1}{n_2}=0.784

now,

calculation of velocity in the medium

n₁ c₁ = n₂ c₂

\dfrac{n_1}{n_2}=\dfrac{c_2}{c_1}

c_2 = c_1\times \dfrac{n_1}{n_2}

c_2 = 7.7\times 0.784

c_2 = 6.04\ Km/s

Speed of wave in the second medium is equal to 6.04 Km/h
