Answer:

1.9 atm

Explanation:

Using Boyle's law :

Pressure is inversely proportional to volume Given that temperature and mass remains constant.

Mathematically ;

P1V1 = P2V2

P1 = 0.95 ; V1 = 1.5L; P2 = ? ; V2 = 1.5 - (1/2*1.5) = 0.75 L

P1V1 = P2V2

0.95 * 1.5 = P2 * 0.75

1.425 = 0.75P2

P2 = 1.425 / 0.75

P2 = 1.9

P2 = 1.9 atm

This question is incomplete because part of the text is missing, here is the complete excerpt for the question:

Read this excerpt from Through the Looking-Glass by Lewis Carroll.

"That would never do, I'm sure," said Alice: "the governess would never think of excusing me lessons for that. If she couldn't remember my name, she'd call me 'Miss!' as the servants do."

"Well, if she said 'Miss,' and didn't say anything more," the Gnat remarked, "of course you'd miss your lessons. That's a joke. I wish YOU had made it."

"Why do you wish I had made it?" Alice asked. "It's a very bad one."

But the Gnat only sighed deeply, while two large tears came rolling down its cheeks.

"You shouldn't make jokes," Alice said, "if it makes you so unhappy."

Then came another of those melancholy little sighs, and this time the poor Gnat really seemed to have sighed itself away, for, when Alice looked up, there was nothing whatever to be seen on the twig, and, as she was getting quite chilly with sitting still so long, she got up and walked on.

The answer to this question is C. The gnat makes jokes, but they seem to cause him unhappiness rather than joy.

Explanation:

Opposites are contradictory elements, characters, actions, or events. In the excerpt from Through the Looking Glass, the author Lewis Carroll used opposite actions in the Gnat character. Indeed, in this dialogue between the Gnat and Alice, the gnat decides to make a joke or funny remark in "Well, if she said 'Miss,' and didn't say anything more...of course you'd miss your lessons"; however, right after this remark, the Gnat is sad and melancholic "the Gnat only sighed deeply, while two large tears came rolling down its cheeks", which shows contradictory or opposite actions.

An essay on the <em>"Roles of Technology in Educating The African Youths"</em>

Technology is the application of modern gadgets or equipment to carry out an activity.

Technology in education is the use of different learning instruments in the classroom such as computer, laptop, projector, scanner etc.

In Africa, education is mostly done using the traditional instruments like chalk and board but the use of technology has increased the interest of students to learn more. They are fascinated with the equipment and it also makes learning easy.
