What force or forces constitute the fundamental source of energy that generates wind movement and circulation?

xz_007 [3.2K]

Answer:

The movement of wind is the result of the action of one or more forces on a particle of air, fundamentally the forces of the solar radiation, pressure gradient, coriolis, friction and centrifugal are recognized.

Explanation:

Air movement is caused by differential heating of the earth's surface and the atmosphere, which presents significant variations in time and space. Wind specifically refers to the horizontal movement of air parcels (which reach great distances and can persist on different time scales)Solar radiation is absorbed by the Earth, and this process is uneven. This irregular heating is what generates the wind. Pressure Gradient Force is determined by the pressure differences between two points in the atmosphere and tends to move the parcels of air from high to low pressure centers, in order to achieve barometric equilibrium. This force is responsible for causing the initial movement of the air. The Coriolis Force is an apparent force that occurs perpendicular to the direction of movement, generating a deviation in the wind path due to the rotation of the Earth (around its axis with an angular velocity). Centrifugal Force manifests itself as a radial pushing action from the center of a circle. In the atmosphere, it occurs in high- and low-pressure systems, leading outward from high- or low-pressure centers. The Friction Force is caused by the friction of the air with the earth's surface, causing a delay in the flow of air masses and changes in the direction of movement.

The average human body contains 6.10 L of blood with a Fe2+ concentration of 1.50×10−5 M . If a person ingests 12.0 mL of 14.0 m

Crank

Answer: The percentage of iron(II) in the blood sequestered by the cyanide ion is 18.4%

Explanation:

Having the reaction NaCN(ac) + Fe2+ ⇒ CNFe + Na+ ; you could follow this procedure:

1. Find the number of moles of Fe2+ in the 6.10L of blood and the number of moles of CN- in the 0.012L (0.012L=12mL) solution.

First, notice that <u>the amount of CN- moles in the 12mL solution is the same as if we were looking for the amount of moles NaCN</u> in the solution. This is because most sodium salts dissociate completely in aqueous solution.

Then having the Molar concentrations of both CN- and Fe2+:

<u><em> Fe2+ concentration =</em></u> 1.5x $10^{-5}$ M = 1.5x $10^{-5}$ moles (n)/L

<u><em> Moles de Fe2+ en 6.01L=</em></u> (1.5x $10^{-5}$ moles (n)/L)*6.01L= 9.15x $10^{-5}$ moles

<em><u> NaCN or CN- concentration =</u></em> 14mM=0,0014M=(0,0014n/L)

<u><em> Moles de CN- en 0,012L=</em></u> (0,0014n/L)*0,012L= 1.68x $10^{-5}$ moles

2. Understand how many moles of Fe2+ are sequestered by CN- :

Beacause 1 mol of CN- react (sequester) with 1 mol of Fe2+ to form 1 mol of CNFe, then 1.68x $10^{-5}$ moles of <u><em>CN- is going to sequester 1.68x $10^{-5}$ moles of Fe2+</em></u> to form 1.68x $10^{-5}$ moles of CNFe.

3. Calculate the percentage of Fe2+ sequestered:

% Fe2+ = (moles of Fe2+ sequestered/Total moles of Fe2+ in the blood)*100

⇒ % Fe2+ = (1.68x $10^{-5}$ ) / (9.15x $10^{-5}$ )=0.184*100 = 18.4% Percentage of Fe2+ moles sequestered by cyanide ion (CN-).

Kryger [21]

Answer:

discovered moons around Jupiter and phases of Venus.

Explanation:

This is because Galileo was a scientist that discovered some proofs to back heliocentric theory. He discovered four moons in the orbit that surrond jupiter and he napped out how the medicean stars where rightly positioned even at night. They would not orbit around Jupiter if the Earth was at tye center of the system. Venus is very close to the sun and it won't go through phases of the Earth is at the system's center.

Heliocentric theory indicate the sun being the centre of the system.

What is the purpose of nitrogen-fixing bacteria?

AveGali [126]

Answer: The symbiotic nitrogen-fixing bacteria invade the root hairs of host plants, where they multiply and stimulate formation of root nodules, enlargements of plant cells and bacteria in intimate association. Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development. brainliest?
