Licemer1 [7]

Cory is reluctant to leave her home and attend college despite just being finished with her teenage years. Usually, the people of this age are explorative and are trying to find their identity in the world separately, but Cory seems to stay isolated even from Mike, which indicates that she might be going through the stage of stress. Stress makes a person to avoid any kind of interaction with other people and inhibits the urge to explore the life outside one's comfort zone. So, Cory is going through the stress stage.

In which sphere does condensation occur? A) Hydrosphere B) Lithosphere C) Biosphere D) Atmosphere
lawyer [7]
<span>The answer is D) atmosphere. There are four spheres of the Earth: 1. Lithosphere (from Greek word 'lithos' = rock), 2. Hydrosphere (from Greek word 'hydros' = water), 3. Biosphere (from Greek word 'bios' = life), and 4. Atmosphere (from Greek word 'atmos' = air). Condensation is the change of water vapour into the water, i.e. the change of water from its gaseous form into liquid form. Since water vapour is the part of air, condensation occur in the atmosphere.</span>

A fish maintains its depth in fresh water by adjusting the air content of porous bone or air sacs to make its average density th
Volgvan

Answer:

0.153

Explanation:

We know the up-thrust on the fish, U = weight of water displaced = weight of fish + weight of air in air sacs.

So ρVg = ρ'V'g + ρ'V"g where ρ = density of water = 1 g/cm³, V = volume of water displaced, g = acceleration due to gravity, ρ'= density of fish = 1.18 g/cm³, V' = initial volume of fish, ρ"= density of air = 0.0012 g/cm³ and V" = volume of expanded air sac.

ρVg = ρ'V'g + ρ"V"g

ρV = ρ'V'g + ρ"V"

Its new body volume = volume of water displaced, V = V' + V"

ρ(V' + V") = ρ'V' + ρ"V"

ρV' + ρV" = ρ'V' + ρ"V"

ρV' - ρ"V'  = ρ'V" - ρV"

(ρ - ρ")V'  = (ρ' - ρ)V"

V'/V" = (ρ - ρ")/(ρ' - ρ)

= (1 g/cm³ - 0.0012 g/cm³)/(1.18 g/cm³ - 1 g/cm³)

= (0.9988 g/cm³ ÷ 0.18 g/cm³)

V'/V" = 5.55

Since V = V' + V"

V' = V - V"

(V - V")/V" = 5.55

V/V" - V"/V" = 5.55

V/V" - 1 = 5.55

V/V" = 5.55 + 1

V/V" = 6.55

V"/V = 1/6.55

V"/V = 0.153

So, the fish must inflate its air sacs to 0.153 of its expanded body volume
