How did the amenities and stimulus of learning help Margrete Cardmore to attain knowledge?

This question is worded somewhat strangely, so I will assume this question asks how education impacted Margaret’s degree of success and understanding of the world around her.
Because Margaret was socially isolated due to the racial prejudices of those around her, she focused on her studies as a child. With her quasi-adopted mother, Margaret Cadmore, being a schoolteacher, the younger Margaret had unfettered access to books and educational materials with which she could study.
These two factors—ease of access and isolation—supported Margaret’s success in school, which led her to become a teacher as well. Therefore, one could argue that her upbringing was the direct result of her attainment of knowledge.
On the other hand, Margaret herself says that she was successful because she sought out to learn, not because she had the resources available.

Why is the governor of Texas considered a weak governor?

Traditionally the office of Governor of Texas is considered a "weak" one because it is held in check by the Lieutenant Governor and Legislature, who together control which bills get passed and make it to the Governor for signature and which bills get tabled and disappear forever. This setup gives the Lieutenant Governor, who acts as President of the Senate, a lot of power regarding the Administration's agenda. The Lieutenant Governor also wields a great deal of power over state finances as a senior member of the Budget Board and appoints legislators to important committees.
However, the Governor has veto power over any bills and also appoints people to state boards and agencies. If the Governor is a savvy politician, they will use their office as a "bully pulpit" and use the media to advance their agenda. They can veto bills too late in the session for the Legislature to take up again. The Governor also has the ability to call a Special Session, during which the Legislature can only consider what the Governor has determined.
If the Governor and Lieutenant Governor are in sync politically, they can get a lot done. If not, the Lieutenant Governor sets the pace and the Governor sometimes acts more as a spoiler.

A gas is at a temperature of 326.0 K and pressure of 810.0 mm Hg. At constant volume, it is cooled down to 273.0 K. Showing and explaining each step, calculate the final pressure.

According to the Gay-Lussac's law, the pressure of a given amount of gas, held at a constant volume, is directly proportional to its temperature (in Kelvin scale).
In other words,

P alpha T

where, P and T are the pressure and temperature of the gas, respectively.
This relation can also be thought of as P/T = constant (at a constant volume).
This relation can be further extended to

P1/T1 = P2/T2

where P1 and P2 are the gas pressures at temperatures T1 K and T2 K, respectively.
In the given question, P1= 810 mm Hg, T1 = 326 K and T2 = 273 K.
Using the above relationship,

P2 = (P1/T1). T2
= (810/326). 273 = 678 mm Hg.

Thus, when the gas is cooled to 273 K at constant volume, its pressure will be 678 mm Hg.
Hope this helps!

What is the relationship between Brutus and Cassius?

Brutus and Cassius are extremely close friends who have known each other for a very long time. It is exactly because they love each other so intensely that they feel able to speak plainly to one another, even when they disagree. Their fiercest arguments are swiftly resolved. There is a telling moment in Act 4, Scene 3, when Brutus confesses that when he spoke harshly, he was "ill-tempered" and did not mean it; Cassius asks for his hand, and Brutus promises his "heart too." Early in the play, Cassius is convinced that his friend Brutus is the most valuable person he can possibly recruit to his cause. He knows that Brutus does not see himself in such a way but offers to be a "mirror" to show Brutus the qualities in himself which he does not suspect are there.
The relationship between the friends is at times turbulent, with each accusing the other of being less skilled militarily and each seeking to persuade the other to his point of view. Ultimately, however, their friendship is built not only on mutual respect but upon the deepest affection.

How does Paton introduce the character of Stephen Kumalo in the second chapter?

The famous novel Cry, the Beloved Country by Alan Paton tells the story of a black pastor in South Africa, Reverend Stephen Kumalo, who journeys from a remote village to the city of Johannesburg to search for his son Absalom.

In the second chapter, readers learn a lot about Kumalo's character as Paton introduces him. First of all, we learn about his compassion. When a small child delivers a letter to him, his primary concern is not about the letter but the child. He asks if the child is hungry, and upon learning that she is, he sends her off to the kitchen to find food.

We also learn that he is married, that he and his wife have a son, and that the son has gone off to Johannesburg and has not returned. We learn that he has a brother named John, a carpenter who lives in Johannesburg, and a sister named Gertrude who took her young child with her to Johannesburg to look for her husband.

In the way that Kumalo and his wife react to the letter that the child has brought, we learn that they do not receive letters very often, that they are worried about their son and anxious to hear from him, and that this letter may be very important. We can discern these things because instead of opening the letter right away, they discuss it and its possible contents first, as if they are apprehensive about what it might say.

After Kumalo and his wife read the letter, we learn of his deep concern for his sister who is sick, but even more for his son in Johannesburg who has not written to them. In this short chapter, Paton is able to introduce Kumalo as a man who is concerned, compassionate, and devoted to his family.

What were some of the major resources of wealth and industry in the original Thirteen Colonies?

Each region of the American colonies had its own form of economic specialization. This was due to the large geographical distances and differences in climate encompassed by the English settlements. For example, the New England colonies, based as they were on the Eastern seaboard, were heavily involved in shipbuilding as well as the manufacture of rum, which could be exported across the Atlantic to the mother country.
The economy of the Southern colonies was, and would remain for centuries, overwhelmingly agrarian. A large variety of crops were grown in the South, most notably cotton, tobacco, indigo, rice, and sugar. The development of these agricultural products—especially cotton—was dependent on slave labor, which formed the basis of Southern economic life right up until the end of the Civil War.
The Middle Colonies, such as Pennsylvania, New York, and Delaware also exported agricultural products, but unlike the Southern colonies, they were able to manufacture iron ore products such as tools, kettles, and plows.

In The Outsiders, how and why does Ponyboy's opinion of the Socs change by the end of the story? Include quotes from the story.

When the story begins, Ponyboy doesn't really even consider the Socs as actual people. The Socs are an enemy group made up of a bunch of spoiled rich kids, and they are to be disliked and fought.

Not like the Socs, who jump greasers and wreck houses and throw beer blasts for kicks, and get editorials in the paper for being a public disgrace one day and an asset to society the next.

Ponyboy's opinion of the Socs begins to change quite early in the story, and much of that has to do with Cherry. She is a Soc, yet she doesn't have a problem talking to Ponyboy. The two characters have some great conversations throughout the book, but already in their first conversation Cherry gets Ponyboy to consider the idea that the Socs are regular people with problems just like the Greasers.

Cherry no longer looked sick, only sad. "I'll bet you think the Socs have it made. The rich kids, the West-side Socs. I'll tell you something, Ponyboy, and it may come as a surprise. We have troubles you've never even heard of. You want to know something?" She looked me straight in the eye. "Things are rough all over."
"I believe you," I said.

As events continue to unfold in the story, Ponyboy's attitude toward the Socs continues to evolve. By the final third of the book, Ponyboy is able to look past the "Soc" label and see Randy for just the guy that he is.

"My name's Ponyboy," I said. "Nice talkin' to you, Randy."
I walked over to Two-Bit, and Randy honked for his friends to come and get into the car. "
What'd he want?" Two-Bit asked. "What'd Mr. Super-Soc have to say?"
"He ain't a Soc," I said, "he's just a guy. He just wanted to talk."
