The average kinetic energy of a gaseous molecules is directly proportional to the absolute temperature. This indicates that the motion of all the molecules stops if the temperature decreases to absolute zero.

The product of each gas molecule's half mass and its square RMS speed yields the average kinetic energy of a gas molecule. In mathematical terms,

[tex]K=\frac{1}{2}mv_{rms}^{2}[/tex]

Here, K = Average kinetic energy

         m = Mass

         vrms = RMS velocity.

The Kelvin scale, where 0 represents absolute zero, is used to measure absolute temperature. The temperature at which matter's particles move the least and cannot cool down is known as the zero point (minimum energy).

[tex]K=\frac{1}{2}mv_{rms}^{2}\\[/tex]

Now, [tex]v_{rms} = \sqrt{\frac{3RT}{M} }[/tex]

Substituiting the value vrms we get,

Highest Abundance: Yellow main-sequence star in open cluster in disk AND hot, blue main-sequence star in disk.

Lowest Abundance: red giant in globular cluster M13 AND red main-sequence star in globular cluster M13.

What is abundance?

Astronomers refer to all chemical elements heavier than hydrogen or helium as metals, including elements such as carbon and oxygen that are not normally considered metals. The metallicity of a star is therefore given as the proportion of these "metallics" in the stellar mass. About 2% for the Sun.

However, this definition cannot fully define the chemical composition of stars. Because you can achieve the same amount of metal in an almost infinite number of ways. For example, a star with a particular metallicity may have all of its metals iron, and another star with the same total metals content may have all of its metals oxygen. In the world, the entire periodic table of elements is present in every star, but the relative abundance of each element varies from star to star.

To quantify the relative abundance of individual elements in a star, astronomers define the "abundance ratio" as the logarithm of the ratio of the star's two metallic elements to the ratio of the Sun.

Therefore,

Highest Abundance: Yellow main-sequence star in open cluster in disk AND hot, blue main-sequence star in disk.

This can be determined by using Newton's law of gravitation. As the gravitational force between Mars and sun can be matched snd hence the sun's effect on Mars can be determined.

How to determine the gravitational force between sun and Mars?

We know, gravitational force is

F=GMmr²

The variables M and m here represent the masses of the Sun and Mars. From this relationship, we can tell that each mass is directly proportional to the force;

F ∝ MF ∝ m

Therefore, any factor that gets multiplied to either mass directly affects the force in the same way. If the sun were twice as massive, then its pull on Mars should thus also twice as much.

The wavelength of the second laser is 0.170mm.

What is wavelength?
The distance over which a periodic wave's shape repeats is known as the wavelength in physics. It is a property of both travelling waves as well as standing waves in addition to other spatial wave patterns. It is the distance between two consecutive intersection point of the same phase just on wave, such as two adjoining crests, troughs, as well as zero crossings. The spatial frequency is the reciprocal of wavelength. The Greek letter lambda () is frequently used to represent wavelength. The term wavelength also is occasionally used to refer to modulated waves, their sinusoidal envelopes, or waves created by the interference of multiple sinusoids.

The distance between the successive maxima and minima of the interference pattern is given by the equation
d/λ = L sin θ

where θ is the angle between the slits and the screen. Since the second laser must produce a maximum at the same location as the fourth minimum of the first laser, the angle θ is equal to 4 times the angle between the first laser and the screen. Thus, the wavelength of the second laser is given by the equation

λ2 = (d/L) sin(4θ)
Substituting in the given values, we have
λ2 = (0.400mm/L) sin(4θ)
where θ is the angle between the first laser and the screen. The value of θ can be found using the equation
d/λ1 = L sin θ|
where λ1 is the wavelength of the first laser. Substituting in the given values, we have
θ = sin-1(d/λ1L)
Substituting this into the equation for λ2, we get
λ2 = (0.400mm/L) sin(4sin-1(d/λ1L))
Therefore, the wavelength of the second laser is given by
λ2 = (0.400mm/L) sin(4sin-1(d/0.400mm/8))
= 0.400mm sin(4sin-1(1/8))
= 0.400mm x 0.425

The frequency heard by the observer is 923 Hz, which is lower than the frequency emitted by the source (1000 Hz).

What is frequency?
The term "disturbance" refers to a moving disturbance. These mechanical waves, which are numerous and must pass through a medium like air or water, must travel. In addition to a vacuum, other types of waves, such as electromagnetic waves, can pass through solid objects. The frequency and wavelength of a wave are two examples of the distinct characteristics that help describe its motion and energy. It is generally understood that frequency refers to the regularity of an event, or more specifically, the regularity of a wave. The wave count that pass through a point in a predetermined amount of time is how frequently waves occur. The amount of waves which pass a point inside one second is another way to define frequency.

The frequency heard by the observer is lower than 1000 Hz. This is due to the Doppler effect, which states that the frequency of a sound heard by an observer moving away from the source is lower than the frequency of the sound emitted by the source.
The change in frequency is given by the formula:
f' = f (v + v_s) / (v - v_o)
where f' is the frequency heard by the observer, f is the frequency emitted by the source, v is the speed of sound, v_s is the speed of the source, and v_o is the speed of the observer.
In this case, f' = 1000 Hz (340 + 0) / (340 - 30) = 923 Hz.
Therefore, the frequency heard by the observer is 923 Hz, which is lower than the frequency emitted by the source (1000 Hz).

As per the details given, the magnitude of the resulting force on the 8 kg mass at the origin due to the gravitational attraction of the other two masses is 1.09 x 10⁻¹¹ N.

To calculate the magnitude of the resulting force on the 8 kg mass at the origin, we need to consider the gravitational forces exerted by the other two masses.

Let's assume the mass at the origin is M₁ = 8 kg, the mass at (0, 6) is M₂ = 16 kg, and the mass at (8, 0) is M3 = 4 kg.

The gravitational force (F) between two masses M₁ and M₂ is given by Newton's law of universal gravitation:

F = G * (M₁ * M₂) / r²

where G is the universal gravitational constant (6.6726 × 10⁻¹¹ N·m²/kg²), M₁ and M₂ are the masses, and r is the distance between the centers of the masses.

1. Gravitational force between M₁ and M₂:

Distance between M₁ and M₂:

r1 = √(0² + 6²) = 6 m

Gravitational force between M₁ and M₂:

F1 = G * (M1 * M2) / r₁²

F1 = 6.6726 × 10⁻¹¹ * (8 kg * 16 kg) / (6 m)²

F1 ≈ 1.0660 × 10⁻¹⁰ N

2. Gravitational force between M₁ and M₃:

Distance between M₁ and M₃:

r₂ = √(8² + 0²) = 8 m

Gravitational force between M₁ and M3:

F₂ = G * (M₁ * M₃) / r₂²

F₂ = 6.6726 × 10⁻¹¹ * (8 kg * 4 kg) / (8 m)²

F₂ ≈ 2.0015 × 10⁻¹¹ N

Now, the resulting force on M₁ is the vector sum of the forces F₁ and F₂. Since the forces are acting along the x-axis and y-axis, we can use the Pythagorean theorem to find the magnitude of the resulting force:

Magnitude of the resulting force on M1:

F' = √(F₁² + F₂²)

F' = √((1.0660 × 10⁻¹⁰ N)² + (2.0015 × 10⁻¹¹ N)²)

F' ≈ √(1.1363 × 10^(-20) N² + 4.0060 × 10⁻²² N²)

F' ≈ √(1.1769 × 10⁻²⁰ N²)

F' ≈ 1.09 × 10⁻¹¹ N

Thus, the resulting force on the 8 kg mass at the origin is approximately 1.09 × 10⁻¹¹ N.
