Qué columna de mercurio (13600 kg/m3) equilibra la presión de 1 atmosfera (Patm = 1.013 x 105 Pa (N/m2))

h = 76 [cm]

Explanation:

Sabemos que la presion atmosferica es igual a:

La presion estatica en una columna de liquido se puede calcular por medio de la siguiente expresion.

donde:

P = pressure [Pa]

Ro = density of the liquid = 13600 [kg/m³]

h = altura de la columna. [m]

b.transmitters send radio waves, and receivers capture radio waves.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
