Help! I am in a hurry! Will get brainliest if correct!

Answer:

A

Explanation:

The Maxwell-Boltzmann equation, is the basis for discussion of the kinetic theory of gases. From it we can understand how gases are distributed at a particular temperature.

Let us remember that the kinetic energy of all gases is the same at the same temperature. However, the distribution of gases depends on their molecular weight at that particular temperature.

Heavier molecules are known to move slowly compared to lighter molecules. Heavier molecules generally have a smaller distribution while lighter molecules spread out.

For this reason, oxygen which is heavier than nitrogen has a smaller distribution as shown in the diagram (molar mass of oxygen = 32g/mol) while nitrogen (molar mass 28 g/mol) has a distribution that is more spread out being a lighter molecule. Hence the option chosen.

Answer:

1.An increment of predators

2.unavailability of food resources due to change in climate causing famine

3.Spread of diseases over time that might kill the squirrels

4.An increment of squirrels which caused high competition on food,thus some of them had to migrate

5.Might be fire break out over some time that caused death to some squirrels in the reasoning of the period of time

In  ecosystem, particles are carried as  bed load by rubbing particles together.Path of stream can be varied depending on amount of humus present in  soil and is measured in cubic meters per second and carrying capacity depends on  type of material through which stream flows.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

volume = final volume of water - initial volume of water

volume = 56.4 - 50 = 6.4 mL

We have

[tex]density = \frac{53.78}{6.4} \\ = 8.403125[/tex]

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Explanation:

The total number of each type of atom always stay the same.

We can verify the properties as follows;

1) Sour taste - Put some soda on your tongue

2) Corrode metals - Put a little soda on a clean metal surface

3) Effect on Litmus paper - Dip a blue litmus paper in soda

4) Electrolysis - Add two electrodes to soda and connect a battery.

Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.

When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:

CO₂ + H₂O ⇌ H₂CO₃

Answer:

Newton's Third Law of Motion states that to every action there is an equal and opposite reaction. When the earth pushes on you to send you into the air after jumping, you also push on the earth with the same force. But forces are different from accelerations. A force F is a push or pull on an object

Friction causes an opposite force

The electronegativity from order of least to highest is:

Ne, Ca, Fe, F

Explanation:

Elements in the periodic table have been arranged based on their level of electronegativity (which is the ability of an atom to attract electrons).

According to Paulings scale of rating elements based on their electronegativity, the electronegativity value of Fe, Ca, Ne, and F are 1.83, 1, 0 and 3.98 respectively.

Hence, based on Pauling scale, the order of electronegativity from least to highest is:

Ne > Ca > Fe > F

Answer:

The material is 30 years old.

Explanation:

The decay of radioactive isotopes can be modelled by the following ordinary differential equation:

[tex]\frac{dm}{dt} = -\frac{m(t)}{\tau}[/tex] (Eq. 1)

Where:

[tex]m(t)[/tex] - Current mass of the isotope, measured in grams.

[tex]\tau[/tex] - Time constant, measured in years.

[tex]\frac{dm}{dt}[/tex] - Rate of change of the isotope in time, measured in grams per year.

After some handling, we find that the solution of the differential equation is:

[tex]\frac{m(t)}{m_{o}} = e^{-\frac{t}{\tau} }[/tex] (Eq. 2)

Where:

[tex]m_{o}[/tex] - Initial mass of the isotope, measured in grams.

[tex]t[/tex] - Time, measured in years.

Now we clear time within the expression above:

[tex]t = -\tau\cdot \ln \frac{m(t)}{m_{o}}[/tex]

Besides, we determine the time constant in terms of the half-life ([tex]t_{1/2}[/tex]), measured in years:

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (Eq. 3)

If we know that [tex]t_{1/2} = 10\,yr[/tex] and [tex]\frac{m(t)}{m_{o}} = 0.125[/tex], then the age of the material is:

[tex]\tau = \frac{10\,yr}{\ln 2}[/tex]

[tex]\tau = 14.427\,yr[/tex]

[tex]t = -(14.427\,yr)\cdot \ln 0.125[/tex]

[tex]t \approx 30\,yr[/tex]

The material is 30 years old.
