Using the graph below, at what depth does the thermocline begin?
MAVERICK [17]

Answer: The thermocline begins at 100 meters of depth.

Step-to-step explanation:-

Thermocline is a transition oceanic water layer between deep and surface water in which water temperature decreases rapidly with increasing depth.

From the given graph it cam be seen that at 100 meters the thermoline begins such that  the temperature drops from 27^{\circ} to 24^{\circ}.

Hence, the thermocline begins at 100 meters of depth.

We would like to estimate how quickly the non-uniformities in gas composition in the alveoli are damped out. Consider an alveolu
Vera_Pavlovna [14]

Answer: It will take 11.775 seconds.

Explanation: As a sphere with a diameter of 0.1 mm, the area of an alveolus is

A = 4.π.r²

r for an alveolus would be: r = 0.00005m or r = 5.10^{-5}m

Finding the area:

A = 4.3.14.(5.10^{-5})²

A = 3.14.10^{-8}m²

The concentration change is to be 90% of the final, so

c = 0.9.3.14.10^{-8}

c = 28.26.10^{-9}

The oxygen diffusivity is 2.4.10^{-9}m²/s, that means in 1 second 2.4.10^{-9} of oxygen spread in one alveolus area. So:

1 second = 2.4.10^{-9}m²

t seconds = 28.26.10^{-9}m²

t = \frac{28.26.10^{-9} }{2.4.10^{-9} }

t = 11.775s

For a concentration change at the center to be 90%, it will take 11.775s.
