Step-by-step explanation:

English

Part 1: For the following paragraphs (I-VI), identify the topic sentence (TS) and supporting sentences (SS). Read each passage (I-VI) and, based on the subject of the chosen sentence, label what you think is a topic sentence or a supporting sentence of the paragraph. Remember: There will be three questions for every passage. That means one topic sentence and two supporting sentences for each paragraph. Sometimes the supporting sentence (SS) will be given to you before the topic sentence (TS). Be sure to pay close attention to the paragraph s main

Step-by-step explanation:

Obtaining a high school diploma is essential because it opens doors to a plethora of opportunities. A high school diploma is a basic educational requirement for most jobs, and it is also necessary to pursue higher education. Additionally, a high school diploma signifies that a person has developed critical thinking, communication, and problem-solving skills, making them more attractive to employers. In today's society, the job market is highly competitive, and having a high school diploma can provide a competitive edge. Moreover, a high school diploma is an accomplishment that provides individuals with a sense of pride and accomplishment, boosting their self-confidence and self-esteem.

Colleges and vocational schools differ in various ways. Colleges typically offer a broad range of academic programs, including liberal arts, sciences, and professional fields. On the other hand, vocational schools specialize in hands-on training in specific fields, such as technology, healthcare, and trades. Another difference is the length of time required to complete a program. College programs typically take longer to complete, ranging from two to four years, while vocational programs can take a few months to two years. Furthermore, the cost of attending a college is usually more expensive than vocational schools. However, a college degree may provide a higher earning potential in the long run.

Incorporating the two paragraphs above, obtaining a high school diploma is a prerequisite for pursuing higher education, such as college or vocational school. The difference between the two lies in the type of education and skills acquired. Colleges offer academic programs that lead to a degree and provide a broad range of knowledge in various fields. Vocational schools, on the other hand, offer specific training in a particular field, such as healthcare, technology, and trades. A high school diploma is necessary to enroll in either, and the choice of which to attend depends on an individual's interests, career goals, and financial resources. In conclusion, obtaining a high school diploma is a significant accomplishment that provides individuals with a competitive edge in pursuing their career and educational goals.

$U=1.29\times 10^{-7}\ J$

Explanation:

Given that

a= 8 cm (square)

A= a ² = 64 cm²

d= 4.2 mm

d₁= 2.1 mm ,K₁= 4.7

d₂=2.1 mm , K₂=2.6

We know that capacitance given as

$C_1=\dfrac{K_1\varepsilon _oA}{d_1}$

$C_1=\dfrac{4.7\times 8.85\times 10^{-12}\times 64\times 10^{-4}}{2.1\times 10^{-3}}$

$C_1=1.26\times 10^{-10}\ F$

$C_2=\dfrac{K_2\varepsilon _oA}{d_2}$

$C_2=\dfrac{2.6\times 8.85\times 10^{-12}\times 64\times 10^{-4}}{2.1\times 10^{-3}}$

$C_2=0.701\times 10^{-10}\ F$

Net capacitance

$C=\dfrac{C_1C_2}{C_1+C_2}$

$C=\dfrac{1.26\times 10^{-10}\times 0.701\times 10^{-10}}{1.26\times 10^{-10}+0.701\times 10^{-10}}\ F$

$C=4.5\times 10^{-11}\ F$

We know that stored energy given as

$U=\dfrac{CV^2}{2}$

V= 76 V

$U=\dfrac{4.5\times 10^{-11}\times 76^2}{2}\ J$

$U=1.29\times 10^{-7}\ J$

Step-by-step answer

P Answered by Specialist

1

1. Correct ¿Quieren estudiar conmingo?

Since I want to ask my friends if they'd like to study with me, I need to conjugate a verb in the simple present matching the third person plural. So quieren is the only conjugation that meets this requirement. Thus, quieren is the conjugation of the verb querer for the third person plural in the simple present. Finally, this might be the dialogue:

- ¿Quieren estudiar conmingo?

- Sí, queremos estudiar contigo

2. Correct A. Tengo que trabajar este fin de semana

This is the correct answer, so I have to work this weekend means Tengo que trabajar este fin de semana. Thus, tengo is the conjugation of the verb tener for the first person singular in the simple present. After this conjugation must come que + an infinitive verb. This infinitive verb is trabajar that means to work. Finally, este fin de semana translates into this weekend.

3. Correct c. Sabes jugar muy bien

If you want to compliment a friend on his or her good game you'd say sabes jugar muy bien that means you know how to play very well. So sabes is the conjugation of the verb saber for the second person singular in the simple present. The verb jugar is an infinitive verb, that is the most basic form of Spanish verbs.

4. Correct d. ¿Quieres ir a la playa conmigo?

Since I'd ask a friend if he or she wants to go to the beach with me, I'd use the conjugation of the verb querer for the second person singular in the simple present, which is quieres. Then, we use the infinitive verb ir and then we talk about the beach. So playa means beach.

5. Correct a. Voy a bailar en la fiesta esta noche

Voy is the conjugation of the verb ir that matches the first person singular in the simple present. On the other hand, bailar is an infinitive verb that means to dance. Also, fiesta means party and esta noche translates into tonight. Finally, voy a bailar en la fiesta esta noche means I'm going to dance at the party tonight

6. Correct c. Ellos juegan al fútbol americano este fin de semana.

In Spanish, futbol translates into fútbol americano and soccer translates into fútbol (less common called balonpié). Therefore, juegan is the conjugation of the verb jugar that matches the third person plural in the simple present. Al is the contraction of a el. Finally, este fin de semana means this weekend.

7. Correct b. ¿puedo ir a estudiar a la biblioteca?

Since I want to ask my teacher that if I can go to study at the library, I would use the verb poder conjugated for the first person singular in the simple present, which is puedo. Next, I'd use the infinitive verb ir and then I'd talk about the library. So biblioteca means library.

8. Correct a. Voy a estudiar mucho mañana

Voy is the conjugation of the verb ir that matches the first person singular in the simple present. On the other hand, estudiar is an infinitive verb that means to study. Also, mucho is an adverb of quantity or degree. Adverbs of manner give information on the way something is done answering questions like How? or In what way? Finally, tomorrow means mañana.

9. Correct c. Béisbol is more important than fútbol in Cuba, Puerto Rico, and la República Dominicana

Béisbol translates into baseball and fútbol means soccer. This sport is more important in those countries because they face each other in the Caribbean Series. This is the highest tournament for professional baseball teams in South America, featuring the champions of Cuba, Dominican Republic, Mexico, Puerto Rico, and Venezuela.

10. Correct a. In U.S. high schools there is more emphasis on sports than in Chile, while schools in Chile place more emphasis on academics and teams represent leagues rather than schools

U.S. high schools focuses more on Sports, This is called High school sport or prep sports and includes sporting competitions at the secondary school level. So there are a lot of athletics programs at this level. On the other hand, Chile place more emphasis on academics and teams represent leagues rather than schools. The focus is on Scientific-humanities and Technical-professional.

11. Correct c. Rebecca Rose Lobo-Rushin’s team

Rebecca Lobo is an American television basketball analyst. She's is better known because she's a former women's basketball player in the Women's National Basketball Association. She was named to the USA U18 team, then called the Junior World Championship Qualifying Team, in 1992. On the other hand, Sammy Sosa is a retired baseball player, Alfonso Soriano is a baseball player and Lorena Ochoa is a professional golfer.
