The air pressure in the rigid tank Decreases.

<u>Explanation:</u>

A rigid tank is said to be a region where volume is always considered as a constant. During the process of cooling the rigid tank where the temperature is said to be decreased, the effect of air pressure in the tank also decreases.

Because, PV = RT, where P is the pressure, T is temperature, R is constant, V is the volume. Hence pressure is directly proportional to temperature.

If the temperature in the tank is decreased this would imply that the kinetic energy of molecule decreases because of the ideal gas law:
PV= nRT (Since Pressure is directly proportional to Temperature).
So the answer is B.The air pressure in the rigid tank decreases.
Hope this helps you.

What does the number, or density, of field lines on a source charge indicate?
Harrizon [31]

Hello.

The answer: C. amount of charge on the source charge

The field lines all represent the movements of field charges.  The more crowded the field lines or the more density of electric field the higher is the magnitude of the source charge.

Have a  nice day.

The membrane that surrounds a certain type of living cell has a surface area of 5.3 x 10-9 m2 and a thickness of 1.1 x 10-8 m. A
kotykmax [81]

Answer:

2.1\times 10^{-12} c

Explanation:

We are given that

Surface area of membrane=5.3\times 10^{-9} m^2

Thickness of membrane=1.1\times 10^{-8} m

Assume that membrane behave like a parallel plate capacitor.

Dielectric constant=5.9

Potential difference between surfaces=85.9 mV

We have to find the charge resides on the outer surface of membrane.

Capacitance between parallel plate capacitor is given by

C=\frac{k\epsilon_0 A}{d}

Substitute the values then we get

Capacitance between parallel plate capacitor=\frac{5.9\times 8.85\times 10^{-12}\times 5.3\times 10^{-9}}{1.1\times 10^{-8}}

C=0.25\times 10^{-12}F

V=85.9 mV=85.9\times 10^{-3}

Q=CV

Q=0.25\times 10^{-12}\times 85.9\times 10^{3}=2.1\times 10^{-12} c

Hence, the charge resides on the outer surface=2.1\times 10^{-12} c

Water vapor enters the atmosphere through
Blizzard [7]

Answer:

Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere. Plants, too, help water get into the atmosphere through a process called transpiration! ... Water can also get into the atmosphere from snow and ice.

Most water vapor enters the atmosphere via evaporation and transpiration. Evaporation occurs when a single water molecule on a liquid water surface gains enough kinetic energy (often by solar radiation) to break the bond which holds the molecules together. Really Hopes this helps!
