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.

The heat required to change 1 gram of a solid at its normal melting point.

Answers

By definition, the heat required to change 1 gram of a solid at its normal melting point is called heat of fusion.

Latent heat is defined as the energy required by a quantity of substance to change state.

When this change consists of changing from a solid to a liquid phase, it is called heat of fusion and when the change occurs from a liquid to a gaseous state, it is called heat of vaporization.

Fusion is the process by which a solid becomes a liquid phase. In this case, the temperature remains constant throughout the time that the solid turns into a liquid.

This occurs because in the solid phase the molecules are held together forming a rigid crystalline structure, in such a way that the substance has a defined shape and volume. As heat is supplied, the energies of the solid's particles gradually increase. After a certain time, this energy becomes so great that some of the particles exceed the force that kept them in their fixed positions.

In this way, the greatest separation between the particles is associated with the liquid phase.

Thus, the energy absorbed by the substance is used to separate the molecules more than in the solid phase, so that the temperature does not increase during the change of state.

In summary, it is called "heat of fusion", the energy required to change 1 gram of substance from a solid state to a liquid state, without changing its temperature.

In others words, the heat required to change 1 gram of a solid at its normal melting point is called heat of fusion.

Ants are really strong. Ants are farmers. Ants are very resilient as a species.

Ants are known to be really strong such that they can carry things that are 50 times their body weight which allows them to carry a lot of food to their colonies.

Ants are also farmers in that they have been known to protect some other insects so that they can keep getting agricultural produce like honeydew.

Ants are also quite resilient in that they have been around for as long as dinosaurs which means they are some of the oldest species in the world.

Ryan invests a sum of money in a savings account with a fixed annual interest rate of 4. 31.

Answers

The amount of his initial investment is $8361

The complete question says:

Ryan invests a sum of money in a savings account with a fixed annual interest rate of 4.31% compounded 12 times per year. After 10 years, the balance reaches $12,855.94. What was the amount of the initial investment?

The initial investment is the amount required to start a particular project,  and the amount of the initial investment can be calculated by using the compound interest formula:

[tex]\mathbf{A = P(1 + \dfrac{r}{n})^{nt}}[/tex]

where;

A = amountP = Principalr = interest rate n = number of months

[tex]\mathbf{12855.94 = P(1 + \dfrac{0.0431}{12})^{12 \times 10}}[/tex]

[tex]\mathbf{12855.94 = P(1 +0.003591666667)^{120}}[/tex]

[tex]\mathbf{12855.94 = P(1.53760)}[/tex]

[tex]\mathbf{P= \dfrac{12855.94}{(1.53760)} }[/tex]

P = $8361.043

P ≅ $8361

A hunter carries a firearm while climbing into and out of a tree stand. What is the proper way to get the firearm into and down from the stand?.

Answers

Considering the situation described above, the proper way to get the firearm into and down from the stand is to use the "haul line like strong rope, strap or commercially made line to carry the firearms."

This is because carrying firearms to climb a tree is dangerous. It is believed that the additional weight of the gun can lead to loss of balance, thereby making the hunter fall.

In some cases, following the hunter's fall, there may be an accidental discharge which may eventually injure or kill the hunter.

Also, when using a haul line to carry the firearms, the hunter still needs to follow certain precautions to avoid accidental discharge, such as unloading of weapons and turning the muzzle upside down.

Hence, in this case, it is concluded that the correct answer is "haul line like strong rope, strap or commercially made line to carry the firearms."
