    What is black? You may have already got an answer, but keep reading because your answer could also be incorrect. You might have the correct solution, but it might not be exactly right so you ought to take your time and keep reading this thoroughly.

    You might think black is just defined as a color, but it isn't, just not the right properties to be defined as just a color. The definition of black goes deeper. Black isn't exactly defined as a color because it's the whole absence of light and shine, and also, color. Within the visible art world, black and white, sometimes are usually defined as distinct colors. This is different from the scenario of spectral colors in physics.

    Black is really a color which ends up from missing or complete absorption of all visible/invisible light. It's a neutral color, without hue, like white and gray. It's often used symbolically or figuratively to represent darkness of the very darkest color because of the absence of or complete absorption of light; the other of white.

    Well black represents darkness, evil, despair, and also the night/the abyss. It is the color accustomed to convey specifically/certain and jurisdiction, and when used because the opposite as white, it is a symbol of the eternal struggle between day and night, well-being and evil/hatred, and right and crime/wrong.

    So in conclusion, black represents darkness, evil, and despair, it is a symbol of the eternal struggle between day and night, well-being and evil, between right and wrong. It is the color accustomed to convey specifically/certain and jurisdiction, and it is also the opposite of white. It is not just a color, it's more known as a distant color because it is without light and hue.

Stories often convey deep meaning. Moses and his stories will complicate the pigs' control over the other animals.

The Animal Farm is known to be a novella that was written by George Orwell. It was known to be written in England in 1945.

The story was about a group of farm animals who fought back against their human farmer. They wanted to a society where the animals can be equal.

The pigs were actually are interested in been in charge of all the animals and the stories of Moses is hindering their agenda.

See full question below

Read the passage from chapter 2 of Animal Farm.

The pigs had an even harder struggle to counteract the lies put about by Moses, the tame raven. Moses, who was Mr. Jones's especial pet, was a spy and a tale-bearer, but he was also a clever talker. He claimed to know of the existence of a mysterious country called Sugarcandy Mountain, to which all animals went when they died. It was situated somewhere up in the sky, a little distance beyond the clouds, Moses said. In Sugarcandy Mountain it was Sunday seven days a week, clover was in season all the year round, and lump sugar and linseed cake grew on the hedges. The animals hated Moses because he told tales and did no work, but some of them believed in Sugarcandy Mountain, and the pigs had to argue very hard to persuade them that there was no such place.

Which prediction does this passage best support?

Moses and his stories will complicate the pigs’ control over the other animals.

The pigs will adopt Moses’s ideas and promote them on Animal Farm.

Moses will die and end up on Sugar candy Mountain, thus proving its existence.

The animals will demand that Moses leave the farm and will force him out.

Answer:

The amount of energy is directly proportional to the photon's electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy.

The energy of photon in visible range will be of [tex]4 \times 10^{-19} J[/tex].

Violet, indigo, blue, green, yellow, orange, and red are hues in the electromagnetic spectrum. Blue light has a very short wavelength and hence creates more energy.

Blue light in the visible zone has a very short wavelength. So that it produces a higher amount of energy that's why the blue part of visible light transfers the most energy.

The photons in the infrared range have the lowest energy and photons in the ultraviolet range have the highest energy.

A photon in the visible range should have an energy which is between the infrared range and the ultraviolet range.

Wherever the maximum energy of a photon in the infrared range is 3 x 10-19 J and the minimum energy of a photon in the ultraviolet range is 5 x 10-19 J,

Thus, photon in the visible range could have an energy of  [tex]4 \times 10^{-19} J[/tex].

The company that will have the lowest balance in a contra account is company-2 , which sold bonds at 94%

Bonds are being usually sold at par, at a discount, or at a premium. There exists no notion of a contra asset if the bonds are sold at par. If the bonds are sold at a discount, the net cash received will be lesser than the amount of par value of the bonds issued. Under this scenario, the bonds payable account can only display the par value of the bonds issued, however, the difference among both the par value of the bonds as well as the net cash actually realized from this kind of bond issue will be parked in a contra account which will be amortized over the bond's tenure.

As such, the lowest balance in the contra account for the four companies can be computed as:

                             company4      company3      company2      company1

Bond par value   $6,000,000   $6,000,000   $6,000,000   $6,000,000

Issued at               105%               101%               94%                  99%

Net cash -          6300000        6060000        5640000        5940000

the value of change in entropy for freezing process of 1 mole of liquid methanol is -18.07 J/mol.k

Explanation:

Entropy is defined as the measure of possible arrangement of the atoms or molecules. Entropy change for the the freezing process mole of 1 liquid methanol at -97.6 degree celcius and 1 atm will be -18.07 J/mol.

The entropy change can be calculated by the given formula:

Thus, the value of change in entropy for freezing process of 1 mole of liquid methanol is -18.07 J/mol.k

(Hope this helps can I pls have brainlist (crown)☺️)

For the freezing of 1 mole of liquid methanol, the change in entropy value is -18.07 J/mol.

The measure of atoms' or molecules' potential arrangements is known as entropy. Entropy change for one mole of liquid methanol frozen at -97.6 degrees Celsius and one atmosphere is -18.07 J/mol.

The range of entropy is 0 to 1. Depending on the number of classes in your dataset, entropy can be greater than 1, but it still indicates a very high level of chaos. For the sake of convenience, the examples in this blog will have entropy values between 0 and 1.

The "information" a variable contains is measured by its entropy. Now, based on the surprise that this value of the bholds and the number of distinct values that are present in the variable, this amount is approximated.

Thus, it is -18.07 J/mol.

A time graph reveals specific information on the velocity (change in position with respect to a change in time).

So, on a position - time graph, the feature representing motion in the negative direction over time is a downward sloping line segment.

A slope in a position time graph depicts the velocity also called the slope in this type of graph as it the change in position over time.

So, a downward sloping line segment feature in a time graph indicates that the motion of the object is in the negative direction. While a positive sloping line segment indicates otherwise.

Stokes' theorem says that the surface integral of the curl of the vector field F across the surface S is equal to the line integral of F along the boundary of S.

In this case, the boundary is a circle in the x,y-plane with radius 2. (To see this, set z = 0 and rearrange the equation for the paraboloid as x² + y² = 4.)

Then

[tex]\displaystyle \iint_S (\nabla\times\vec F)\cdot d\vec s = \int_{\partial S} \vec F \cdot d\vec r[/tex]

where

[tex]\vec r = 2\cos(t) \,\vec\imath + 2\sin(t) \,\vec\jmath[/tex]

parameterizes the circular boundary of S with 0 ≤ t ≤ 2π. Then

[tex]d\vec r = \dfrac{d\vec r}{dt}\,\dt = (-2\sin(t)\,\vec\imath + 2\cos(t)\,\vec\jmath)\,dt[/tex]

and the integral becomes

[tex]\displaystyle \iint_S (\nabla\times\vec F)\cdot d\vec s = \int_{\partial S} \vec F \cdot d\vec r[/tex]

[tex]\displaystyle \iint_S (\nabla\times\vec F)\cdot d\vec s = \int_0^{2\pi} \vec F(\vec r(t)) \cdot \frac{d\vec r}{dt}\,dt[/tex]

[tex]\displaystyle \iint_S (\nabla\times\vec F)\cdot d\vec s \\= \int_0^{2\pi} ((2\cos(t))^2 \sin(0)\,\vec\imath + (2\sin(t))^2\,\vec\jmath + (2\cos(t))(2\sin(t))\,\vec k) \cdot(-2\sin(t)\,\vec\imath + 2\cos(t)\,\vec\jmath)\,dt[/tex]

[tex]\displaystyle \iint_S (\nabla\times\vec F)\cdot d\vec s = \int_0^{2\pi} 8\sin^2(t)\cos(t) \, dt[/tex]

[tex]\displaystyle \iint_S (\nabla\times\vec F)\cdot d\vec s = \int_0^{2\pi} 8\sin^2(t) \, d(\sin(t))[/tex]
