What is the kinetic energy (in j) of an n2 molecule moving at this speed?

Answers

Answer 1
1 molecule N2 x (28.0 g / 6.02 x 10^23 molecules) = 4.65 x 10^-23 g = 4.65 x 10^-26 kg/molecule 1. KE = 1/2 m v^2 = 0.5 x 4.65 x 10^-26 kg x (469.4 m/s)^2 = 5.12 x 10^-21 J/molecule 2. ... kinetic energy=(1/2)m*speed^2
Answer 2
Final answer:

The kinetic energy of an N2 molecule moving at a certain speed can be calculated using the formula: KE = (1/2) * mass * speed^2. Substituting the given values, we find the kinetic energy to be 8 * 10^-25 J.

Explanation:

The kinetic energy of an N2 molecule moving at a certain speed can be calculated using the formula:
Kinetic Energy = (1/2) * (mass of the molecule) * (speed of the molecule)^2.

Assuming the mass of an N2 molecule is approximately 2 * 10^-26 kg, and the given speed is 20.0 m/s, we can substitute these values into the formula to find the kinetic energy:


Kinetic Energy = (1/2) * (2 * 10^-26 kg) * (20.0 m/s)^2 = 8 * 10^-25 J.

How can you best describe the relationship between advertising and television?

Answers

Advertisements pay to have their adds on television. Television companies like getting money (Don't we all?). I'd say a business relationship.
Advertising is the life blood of television, and the reason it exists.

Television is in business to earn a profit for its owners. In order to earn profit, it sells product to its customers. Advertisers are the customers, and the product it sells is the eyes of the viewers. The news, sports, and entertainment programs are the bait used to attract the product to be sold to the customers.

Answer:

c-is at the root of our democratic culture.

Explanation:

The word democracy is comprised of two Greek words that are 'demos' means people and 'Kratos' means rule. A state in Greece called Athens is considered to be its birthplace. The very idea that participation of citizens of a kingdom should have active rule in its government by electing members, is deeply rooted in Greek culture. However, the meaning of Democracy in Greek culture was only extended to the active citizens which exclude women, slaves, and children.

How is faith knowledge different from consensus knowledge?

Answers

Faith-knowledge is different from consensus knowledge because faith-knowledge is based on your belief of something from either experience or facts, but consensus knowledge is based on the belief of something that many people hold to be true or reliable. 

Consensus knowledge is different from faith knowledge in that consensus knowledge is based on what many people believe to be true or dependable, whereas faith knowledge is based on what you believe based on facts or experience.

What is knowledge?

Knowledge may be referred to as familiarity with things or circumstances, as well as factual awareness or practical abilities. Factual knowledge, also known as propositional knowledge, is frequently characterized as a real belief that can be distinguished from opinion or conjecture by the presence of supporting evidence.

Although there is broad agreement amongst philosophers that propositional knowledge is a type of true belief, many philosophical debates center on justification, including whether it is even necessary, how to understand it, and whether something else is required in addition to it. A series of thought experiments by Edmund Gettier contributed to the escalation of these debates and the emergence of numerous competing definitions.

What is robert macneil's main point in "the trouble with television"?

Answers

c
that is the anwser

hope this helps :)

Robert MacNeil's main point in "The Trouble with Television" is that television diminishes our ability to think critically and engage meaningfully with information.

He believes that the medium's fast-paced and superficial nature discourages deep reflection and thoughtful analysis. MacNeil asserts that television's emphasis on entertainment over education contributes to a less informed and more passive populace.

MacNeil also points out that television's addictive quality can lead to excessive consumption, further detracting from time that could be spent on more intellectually stimulating activities.

He emphasizes the need for viewers to consciously limit their consumption. By doing so, he suggests that individuals can reclaim their ability to think critically and engage more deeply with the world around them.

Comparing the Irish diaspora to the Syrian diaspora, decide and explain your opinion as to whether the Syrian refugees should be supported or not. Answers should be in complete sentences. Your answer should be at least 150 words in length and supported by at least one outside source.

Answers

The Irish diaspora refers to people of Irish origin who loved abroad. Since 1700, around 9 or 10 million Irish people have emigrated. The phenomenon was particularly active after 1840. In 1890, 40% of Irish people were living abroad, and in the present, more than 80 million people all over the world (including 36 million Americans, or 10.5% of the population according to the U.S. Census Bureau, 2013) claim to have Irish ancestry.

The arrival of Irish people to the US had many significant changes in society. Because they often spoke Irish (Gaelic), the English language became richer due to their linguistic contributions. Other areas such as music and dance were greatly influenced by the Irish communities. Irish people became involved in all areas of life, including politics, and are now assimilated into mainstream American culture.

The precedent of Irish-Americans supports the idea of accepting Syrian refugees as well. Syrian refugees can contribute to the economy and the culture of the country. They can also become assimilated and participate in all areas of life. Finally, when Syria returns to a stable state, refugees are likely to decrease, as was the case with Ireland.

The Alien and Sedition Acts of 1798 were deemed to be in clear violation of the Bill of Rights, according to Jeffersonian Republicans. 

The Alien and the Sedition Acts were passed by the federalists and eventually signed into law by President Adams. The Alien Act gave power to the president to arrest, detain, and deport any non-citizen of the country who were found to be a threat to the nation's security. The "alien" had no right to hearing or to present evidence in his defense. The Sedition Act prohibited the people from even just criticizing the president, the congress or the U.S. government, limiting the people's freedom of speech and the press.

culture of poverty ....................................................................................................

Answer:

The answer to this question: Which perspective claims that poverty is outside of human control, would be, B: Social Structuralism, better known simply as the Structural causes of poverty theory.

Explanation:

The reason is that all other options, especially Individualism, and Culture of Poverty, state that it is for reasons whithin the person´s choices, be it due to organical, or physical issues, or due to culture itself, that people choose to remain in poverty and generationally, this remains the same (culture of poverty). However, it is the Structural theory of poverty that explains that it is rather due to the socio-economic frameworks under which the world now functions, particularly capitalism, that people remain in poverty, and these frameworks need to change in order to change the situation of poverty.
