One of the deepest freedives (i. e. without any breathing apparatus) to date was achieved by goran colak of serbia when he dove to a depth of 288 m in 2014. if the density of sea water is 1030 kg/m3 and the atmospheric pressure at sea level (1 atm) is 105 pa, what is the approximate pressure experienced by goran at that depth

3010038.4 Pa

Explanation:

= Atmospheric pressure =

= Density of sea water = 1030 kg/m³

g = Acceleration due to gravity = 9.81 m/s²

h = Depth = 288 m

The total pressure at the given depth is given by

The pressure experienced by Goran at that depth is 3010038.4 Pa

explanation:

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.
