What are the five main types of precipitation?

Precipitation is a form of water that falls from a cloud. Five main types of precipitation are rain, snow, hail, sleet, and freezing rain. Each of the five main forms of precipitation are briefly explained below.

Rain

Rain is in the form of liquid water. It is by far the most common form of precipitation.

Snow

Snow forms via sublimation. In other words, snow forms when water vapor turns directly into a solid state (ice) without first becoming a liquid.

Hail

Hail forms in cumulonimbus clouds. Ice crystals that begin to fall towards Earth’s surface are lifted by a gust of wind within the cloud. Thus, they are brought up higher into the cloud. As this occurs, the hail grows in size as it accumulates more moisture within the cloud. The blowing of a hail ball back up into the cloud can occur several times. Eventually, a hail ball becomes so large and heavy that it falls to Earth.

Sleet

Sleet is a mixture of snow and rain. Sleet is formed when raindrops travel through a cold region of the atmosphere on their way down to Earth. This causes the raindrops to slightly freeze.

Freezing Rain

Freezing rain does not freeze on the way down to Earth. Rather, freezing rain freezes as soon as it hits an object on Earth.

What is the difference between Ionic and Molecular compounds

Ionic compounds are between cation and anions. They are usually between a metal and a nonmetal or a polyatomic ion. Ionic compounds are bonded with the cation “giving away” its valence electrons and the anion “receiving” them for a full octet.

Molecular compounds are usually between two or more nonmetals. The nonmetals simply share their valence electrons for a full octet.

When the difference in electronegativity of two atoms is greater than 1.7, the bond is ionic. When it is less than 1.7 but greater than 0.4, the bond is polar covalent. When the difference is less than 0.4, the bond is nonpolar covalent.

One difference between molecular compounds and ionic compounds is that molecular compounds are formed by the sharing of electrons, and ionic compounds are formed by the transfer of electrons. Molecular compounds result from covalent bonding and ionic compounds result from ionic bonding. Another difference is that a molecular bond is formed between two non-metals, and an ionic bond is formed between a metal and a non-metal.

Allegory of the Cave Summary

What is the main theme of Plato’s “Allegory of the Cave” in the Republic?

The main theme of Plato’s Allegory of the Cave in the Republic is that human perception cannot derive true knowledge, and instead, real knowledge can only come via philosophical reasoning.

In Plato’s example, prisoners live their entire lives in a cave, only able to see shadows. To them, these shadows are reality. When a prisoner randomly guesses the next shadow to appear, that prisoner will be worshipped as having mastered nature. When one prisoner escapes and understands that life comes from the sun, he realizes his former view of reality based on human perception was wrong. When he returns to tell the other prisoners, they do not believe him, because they are still relying on their perception.

This idea also begins to uncover other issues with human perception. Humans are biased individuals who will explicitly or implicitly apply individual biases to what they perceive. Additionally, two humans can perceive the same object and derive a different meaning from it. For example, a rainstorm can be viewed as a blessing by a farmer or a curse by a sailor.

Ultimately, Plato’s point is that in order to truly gain an understanding of knowledge, humans must submit to the idea of specific and fair philosophical reasoning, which transcends the pitfalls of human perception.

The Allegory of the Cave represents an expression of Plato’s philosophy of truth and reality (which can be termed as Platonic Idealism). When reading Plato’s various dialogues, one will often observe a focus upon themes such as justice, virtue, beauty, and the good. For Plato, these various concepts are not human inventions, but are actually built into reality itself, as part of a more transcendent reality (one that is actually more real, in a Platonic sense, than the material world as it is experienced by human beings).

The Allegory of the Cave serves to illustrate this relationship in more concrete terms, with the prisoners serving as a representation of human existence. Just as the prisoners are ultimately trapped in their cave, watching shadows on the wall, so too are human beings trapped by their material existence (with all of our knowledge and assumptions of the world being much like those shadows). Yet truth still exists. Even as the prisoners remain trapped in the cave, there is still the world outside the cave. This represents the reality of transcendent ideals which Plato speaks about.

Thus, this entire allegory sketches the Platonic vision of reality, in which human beings are only able to indirectly grasp the higher, transcendent reality which emanates through the universe.

The answer above offers a fine description and explanation of Plato’s allegory of the cave. To expand on it a bit, the theme of the cave allegory gets to the heart of the divide between science and philosophy in Western culture. Plato says we on earth live in a cave, watching shadows on a wall. What we think is real—the natural world—is a pale and imperfect reflection of an ideal reality. He wants us to understand this so that we realize that philosophy is superior to science.

For example, we may think the table in front of us is a real table, worthy of study, and not merely an imperfect imitation of an ideal table. However, we can use the following thought experiment to show that any table we try to build in this world, no matter how perfect we try to make it, is just a shadow of the ideal table. Say we decide to build our table to 1/16″ accuracy. That is crude and imperfect: we could always build it to 1/32″ accuracy. But that too is crude and imperfect: why not build to 1/64″ accuracy? Or for that matter, why not build to 1/100,000″ accuracy? But no matter how accurate our measurements, we could always make the table more accurate: hence it will never, in this world, be the ideal table.

Therefore, according to the allegory of the cave, studying the natural world (science) is less worthy than studying philosophy because a scientist is always studying a shadow, an imperfect imitation of the ideal. The only way to truly contemplate reality is to go inward, to use the human mind to imagine the ideal, which is the province of philosophy.

What are the advantages and disadvantages of computers?

The advantages of computers are obvious and have been covered by the previous answers. I would like to discuss the disadvantages.

Computers have put millions of people out of work. For example, they have ravaged the book-selling business. Book stores are closing all across the country because it is so much more convenient to buy books online and so much easier to find the books you want. But in many cases it is possible to read books on the monitor or to print them. Computers have created jobs but not as many as they have displaced. They are only in their infancy, too. More and more shopping is being done online. Even the supermarkets are being affected. It looks as though the cities are going to be transformed in coming years, and many small towns are already being wiped out of existence.

Another disadvantage of personal computers is that they are addictive. Everywhere you go you see people staring into their laptops, and you may wonder, as I do, what they are thinking and what they find so hypnotic.

The advantages of computers are many. One advantage is their time saving nature. It is much quicker to type a letter than to write one with a pen. The connection to the internet is of great use. The ability to research something or ask questions in real time is amazing. The amount of data that can be stored, manipulated, and retrieved is phenominal. Using the computer save natural resources by limiting our need of paper and pencils.

A disadvantage of computers is when they break down. Most people do not know how to fix them and have to take them to be repaired. Our growing dependence on computers is concerning. Everything is run by computer now and when one goes down it impacts many. Another disadvantage of computers is that some children spend too much time on them. Due to this, their social development may be stunted.

Merchant of Venice Short Summary

A fortuneless nobleman, Bassanio, asks for a loan from the merchant Antonio so that he can pursue Portia, a wealthy heiress, in order to restore his fortune. Since the merchant has all his assets tied up with ships that at sea, he tells Bassanio he will use his credit to obtain a loan from the Jew Shylock. Because Shylock fiercely hates Antonio, he latches on to the opportunity to get revenge; he agrees to loan Antonio the money. But, if Antonio does not repay this loan, Shylock will get a pound of flesh as payment from him.

With the money he needs, Bassanio pursues Portia, and he selects the casket (small box) that allows him to marry her. But, in the meantime, Shylock’s daughter runs off with a Christian, converts, and steals her late mothers jewels. The avaricious and offended Shylock is enraged by this; he vows to exact the flesh from Antonio, who is unable to pay the loan because his ships are lost at sea. When Portia learns from Bassanio of Antonio’s plight, she disguises herself as a doctor of law and, with her servant Nerissa dressed as a law clerk, Portia appears at court on Antonio’s behalf where Shylock demands of the Duke,

I have possessed your grace of what I purpose
And by our holy Sabbath have I sworn
To have the due and forfeit of my bond” (4.1.34-36).

Portia’s speech before the court is clearly a statement of theme for this drama:

The quality of mercy is not strain’d;
It droppeth as the gentle rain from heaven
Upon the place beneath. It is twice blest:
It blesseth him that gives and him that takes.
‘Tis mightiest in the mightiest; it becomes
The throned monarch better than his crown. (4.1.186-192)

While it seems that Portia goes along with the sentencing, when Shylock takes steps to cut off his pound of flesh, Portia/the doctor of law points out that there was no provision in the conditions for Antonio’s blood, so Shylock can only have flesh–no blood. Defeated, Shylock is further humiliated as he is made to convert to Christianity. Antonio’s ships finally arrive and the lovers, Bassanio and Portia, are married.

What is the order of colors in a rainbow?

What is the order of colors in a rainbow?

The order of the rainbow is ROYGBIV (red, orange, yellow, green, blue, indigo, and violet). It is caused by a breakup of white light wavelength (all colors) when it hits water. It is refracted as it passes through the water droplets in the sky (moisture after rain) and breaks into 7 different sizes of wavelengths. The largest of the color wavelength is Red and the smallest is Violet. They have the different sizes due to the amount of energy they come with as they travel from the sun to our eyes!

Violet, Indigo, Blue, Green, Yellow, Orange, Red.

You must remember though that red is the longest wavelength in the visible spectrum and appears at the top of rainbows and to the left-hand side on a horizontal wavelength spectrum while violet is the shortest wavelength in the visible spectrum and appears on the bottom of rainbows and to the right-hand side on a horizontal wavelength spectrum. So, reading left to right, the order of the colors is red, orange, yellow, green, blue, indigo and violet:

ROYGBIV

These are the seven colours on the visible spectrum. Beyond violet are the ultraviolet rays and before red are the infrared rays.

Why did the United States enter World War I?

World War I is the “Great War”, the war to end all wars. The United States wanted the world to know, we were NEUTRAL, but were we really?

Politically, economically and psychologically, we were not isolated by any means. The U.S. did not want to commit to a war, continents away. Let those in war’s path do the dirty work, we would make money off of their involvment. It was enevitable and we were doing our part in other ways.

We sold our allies war supplies, remember the Lusitania and so many ships traveling cross-Atlantic?

We made gained ecomonic profits, we did see our young men rally, volunteer and die with our allies, and yes we provided strategic support in many realms.

Did we have a choice? Neutrality in its pure form was not an option. The Industrial Revolution bound the world together. We could not publically commit in 1914, but in 1917 we had little choice due to the losses of our allies.

The United States people saw itself as the “savior” of the righteous, but our politicians had already set us up by involving the U.S. behind closed doors.

This was a war that resulted from Industrialization, Nationalism and Imperialism. The world was changed forever. Larger countries felt a moral duty to defend and profit.

Consider this, the world was in a great depression and the world was left in a greater depression following WWI.

One thing we would never stand for was the “Zimmerman” telegraph event. The Monroe Doctorine would be defended, no matter what the cost.

The United States, led by President Woodrow Wilson, did not want to be involved in World War I. When Wilson ran for re-election in 1916, his campaign slogan was “He kept us out of the war” referring to the European conflict that was then referred to as the “Great War.” However, by 1917, sentiment was changing with regard to the war.

Although the U.S. had yet to become officially involved in the war, most Americans supported the Allies and saw the Germans as aggressors. Americans felt a connection to Great Britain, in particular, because of cultural similarities. Germany angered Americans with their U-boats sinking American ships suspected of aiding the Allies. With the sinking of the Lusitania in 1915, a British cruise ship, 128 Americans were among those who lost their lives. The Germans temporarily halted such actions but in 1917 resumed unrestricted Naval warfare. At the same time, the British intercepted a message, called the Zimmerman Note, asking the government of Mexico to declare war on the U.S., if war broke out between the U. S. and Germany. The note also promised to help Mexico regain the territory of Texas, Arizona, and New Mexico if Mexico declared war on the United States. This note was the final push that Wilson needed to turn public sentiment towards war. The U.S. Congress declared war on Germany on April 6, 1917.

What does “X” mean after Malcolm’s name?

The X is meant to symbolize Malcolm’s true family name from Africa, which he does not know, since white slave traders violently severed his family.

In his autobiography, Malcolm X writes,

“X” replaced the white slavemaster name of “Little” which some blue-eyed devil named Little had imposed upon my paternal forebears. The receipt of my “X” meant that forever after in the nation of Islam, I would be known as Malcolm X. Mr. Muhammad taught that we would keep this “X” until God Himself returned and gave us a Holy Name from His own mouth.

He speaks about hearing Elijah Muhammad speak about how black men in America were mentally, morally, and spiritually dead because of their mistreatment and brainwashing by white people. One of the things Muhammad discussed that Malcolm X took note of was how black people weren’t able to keep their family names. Their names were replaced with the names of the slaveowners who purchased them.

Muhammad believed that the true knowledge of themselves would help lift up black men in America. Malcolm X learned about the Nation of Islam while he was in prison. He converted and, in the process, changed his name. Later in life, he converted from the Nation of Islam to standard Islam. At that point, he began using the name El-Hajj Malik El-Shabazz.

Malcolm’s original family surname was Little. When in prison, he became part of the Nation of Islam. This religious group believed that blacks had originally been Muslims when taken captive and brought to America as slaves. The group wanted to separate itself from white culture and promote black culture and independence.

Malcolm actually legally changed his last name from Little to X when he was released from prison in 1952. He felt that Little was a name that had been imposed on his family in the past by white slaveowners. The last name X brought him back, he thought, to his lost African roots and helped him develop a sense of black pride and separation from white culture. It worked out to be a distinctive name that helped him remain memorable after he rose to prominence.
