What are air lenses in nuclear bombs? Every website mentioning them just mentions them & doesn't tell what they are. They were used in the Swan device. And please define what they are--don't tell about the Nagasaki & Hiroshima bombs.

Answers

Answer 1

Answer:

Air lenses in nuclear bombs refer to the use of gases such as helium, neon, and xenon to create a high-pressure area around the nuclear core. This high-pressure area reflects the energy released by the explosion back towards the core, which results in a more complete and powerful nuclear reaction. The air lens technique was developed as a way to increase the yield of nuclear explosions without the need for additional materials or larger bombs. The Swan device was a British nuclear weapon design that utilized an air lens for increased efficiency.

What is "For to everyone who has, more will be given, and he will have abundance; but from him who does not have, even what he has will be taken away. " often paraphrased as?

Answers

The quote "For to everyone who has, more will be given, and he will have abundance; but from him who does not have, even what he has will be taken away" is often paraphrased as "The rich get richer, and the poor get poorer."

This paraphrase captures the essence of the quote, which reflects the concept of wealth accumulation and inequality. It suggests that those who already possess wealth or resources will continue to gain more, leading to abundance, while those who are lacking will experience further deprivation. This phrase is often used to describe a socio-economic phenomenon where disparities in wealth and opportunity perpetuate over time, with the affluent benefiting from advantages and the disadvantaged facing increased challenges. It highlights the unequal distribution of resources and the potential for a cycle of poverty and wealth concentration.

Internet Access in China

Issue

Around the world, people use the internet to access information, entertainment, and more. We tend to think of the internet as a system that lacks control, and which everyone is able to access. However, this is not the case in China. China follows a strict mechanism of censorship that restricts the internet for Chinese people. This censorship and surveillance affects roughly 700 million users. Many of these have fought in different ways for free access.

Key people and organizations

It is not easy to establish who is fighting against the system, as these people are often hiding from authorities. However, this group often includes hackers, coders, software programmers, political activists, developers and virtual private network (VPN) suppliers.

Methods and strategies

One of the strategies these groups use is that of developing code or other tools to circumvent the government's censorship. Famous examples are Shadowsocks and GoAgent. VPN allows users to tunnel into the Internet via a different country. Therefore, these are popular among users as well.

TRUE/FALSE. between 2005 and 2007, asphalt firms in kentucky practiced tacit collusion.

Answers

It is True that between 2005 and 2007, asphalt firms in kentucky practiced tacit collusion.

Tacit collusion refers to a situation where competing firms engage in a coordinated behavior that leads to higher prices and reduced competition, without any explicit agreement or communication.

Instead, the firms may use implicit signals or understandings to coordinate their actions, such as following the lead of a dominant firm or matching each other's prices.

Tacit collusion occurs when firms in a market engage in coordinated behavior without any explicit agreement or communication. They might do this by following the actions of a dominant firm or by making strategic decisions based on their understanding of the market.

In the case of asphalt firms in Kentucky between 2005 and 2007, there was evidence of tacit collusion. According to a study by the Kentucky Legislative Research Commission, during this period, asphalt prices increased significantly, and there was a high level of concentration in the market.

The study found that the price increases were not entirely due to the rising costs of raw materials, such as oil. Instead, it was suggested that the high market concentration allowed firms to coordinate their pricing decisions and effectively raise prices without any explicit agreement or communication.

This behavior is consistent with the concept of tacit collusion, where firms in a concentrated market engage in coordinated pricing strategies without explicit communication or agreements.

In the case of the Kentucky asphalt market, the evidence suggests that this type of collusion was practiced between 2005 and 2007.

In conclusion, it is accurate to say that between 2005 and 2007, asphalt firms in Kentucky practiced tacit collusion, leading to increased prices and market concentration during that time period.

How did agricultural subsidies change after the Agricultural Adjustment Act (AAA) was found to be unconstitutional in 1936?

A) Under the AAA, subsidies were used to pay farmers to destroy product or leave fields barren unlike today where they are used to produce extra food for market.
B) Under the AAA, subsidies were not used unlike today where they are used to heavily fund farmers to grow specifically needed crops.
C) Under the AAA, subsidies were used to pay small farmers where today they are used to fund large corporate entities.
D) Under the AAA, subsidies were used to collectivize farms into large entities where today they are used to fund small independent farmers.

Answers

Under the AAA, subsidies were used to pay farmers to destroy products or leave fields barren unlike today where they are used to produce extra food for the market, is the correct statement. So the answer is option A.

In 1933, Congress established the Agricultural Adjustment Act (AAA) to assist farmers by giving subsidies to cut production and boost crop prices. However, the AAA was declared unconstitutional by the Supreme Court in 1936. As a result, the government enacted the Agricultural Adjustment Act of 1938, which rewarded farmers with incentives for growing crops rather than destroying them. The new act also includes provisions for soil protection and other farm productivity and income-boosting initiatives.

Option A is hence the proper statement. The AAA did offer farmers with subsidies, but these payments were used to bribe farmers to destroy crops or leave fields fallow, reducing supply and raising prices. This was considered as a solution to the problem of overproduction, which had resulted in declining crop prices and economic troubles for many farmers during the Great Depression.

However, after the AAA was declared unconstitutional, the government shifted its focus to providing subsidies for production rather than destruction, as stated in Option A.

The article focuses primarily on the United States' perspective in the 20th century during the Cold War in Asia. It provides details about the U.S. involvement in the region and its efforts to contain the spread of communism, particularly in countries like China and Korea.

The article highlights the U.S. perception of communism as a threat to democracy and capitalism, leading to its active engagement in military interventions and diplomatic maneuvers.

The article further elaborates on the U.S.'s strategic alliances, such as the formation of SEATO (Southeast Asia Treaty Organization) and support for anti-communist governments in the region. It mentions the U.S.'s concern about the spread of communism and the potential domino effect if one country were to fall under communist influence.

On the other hand, the article does not fully develop China's perspective during the Cold War in Asia. While China's involvement and perspective are briefly mentioned in relation to the Korean War and its support for North Korea, the article primarily focuses on the United States' actions and policies.

Choose a labor union and briefly describe who they were and what they did.

Answers

The labor union chosen for description is the American Federation of Labor (AFL). Founded in 1886, the AFL was a federation of skilled craft unions that advocated for workers' rights, higher wages, and improved working conditions through collective bargaining and strikes.

The American Federation of Labor (AFL) was a significant labor union in the United States during the late 19th and early 20th centuries. It was founded in 1886 by Samuel Gompers and served as a federation of various skilled craft unions. The AFL primarily represented the interests of skilled workers, such as carpenters, plumbers, and electricians.

The AFL focused on achieving better working conditions, higher wages, and improved benefits for its members. It believed in the power of collective bargaining, where the union negotiated with employers on behalf of its members to secure favorable terms of employment. The AFL emphasized the idea of "bread and butter" unionism, focusing on immediate and practical gains for workers rather than broader political or social reforms.

The AFL played a significant role in the labor movement, advocating for the eight-hour workday, workplace safety regulations, and the end of child labor. It also organized strikes and boycotts to put pressure on employers to meet the demands of workers. The AFL's approach of organizing skilled workers and negotiating with employers influenced the development of modern labor practices and set the foundation for later labor unions in the United States.

Emerald bout 50 pineapples at 50coins each and sold the for $31. 0. Calculate the profit on the 50 pineapples

Answers

Emerald's profit on the 50 pineapples can be calculated by subtracting the total cost of purchasing the pineapples from the total revenue generated from their sale.

To calculate the profit on the 50 pineapples, we need to determine the total cost and the total revenue. Emerald bought 50 pineapples at a cost of 50 coins each, resulting in a total cost of 50 coins x 50 pineapples = 2500 coins.

Emerald then sold the pineapples for $31.00. Since the currency is not specified, let's assume it is in dollars. Therefore, the total revenue from the sale of the pineapples is $31.00.

To calculate the profit, we subtract the total cost from the total revenue: $31.00 - $2500 = -$2469.00.

The negative value indicates a loss rather than a profit. In this case, Emerald incurred a loss of $2469.00 on the 50 pineapples.

It's important to note that the profitability of the transaction depends on various factors such as the initial cost of the pineapples, additional expenses (e.g., transportation, packaging), and the selling price. Without more information, we can only calculate the profit/loss based on the given figures.

The profit on the 50 pineapples is $6.00.Emerald bout 50 pineapples at 50coins each and sold the for $31. 0.

To calculate the profit on the 50 pineapples, we need to determine the total cost of purchasing the pineapples and subtract it from the total revenue generated from selling them.

given:

number of pineapples bought: 50

cost of each pineapple: 50 coins

total revenue from selling: $31.00

step 1: calculate the total cost of purchasing the pineapples:

total cost = number of pineapples bought * cost of each pineapple

total cost = 50 * 50 coins

step 2: convert the cost to dollars:

total cost in dollars = (total cost in coins) / (exchange rate from coins to dollars)

note: the exchange rate is not provided in the given information, so we'll assume an exchange rate of 1 coin = $0.01 (1 cent).

total cost in dollars = (50 * 50 coins) * ($0.01/coin)

step 3: calculate the profit:

profit = total revenue - total cost in dollars

profit = $31.00 - total cost in dollars

let's calculate the total cost in dollars first:

total cost in dollars = (50 * 50 coins) * ($0.01/coin)

total cost in dollars = 2500 coins * $0.01/coin

total cost in dollars = $25.00

Answers

Starting with 100.0 grams of carbon and an excess of silicon dioxide and calcium phosphate, the number of moles of phosphorus produced can be calculated using the balanced chemical equation and the molar masses of the substances involved.

To determine the number of moles of phosphorus produced, we need to use the balanced chemical equation and the molar masses of the substances involved. The balanced equation provided shows the reaction between calcium phosphate (Ca3(PO4)2), silicon dioxide (SiO2), carbon (C), and phosphorus (P), along with the products calcium silicate (CaSiO3) and carbon monoxide (CO). However, it seems that the equation you provided is not balanced correctly. To accurately calculate the number of moles of phosphorus produced, a balanced equation is necessary.

Once the balanced equation is obtained, we can convert the given mass of carbon (100.0 grams) to moles using its molar mass. Then, using the stoichiometry of the balanced equation, we can determine the molar ratio between carbon and phosphorus to calculate the number of moles of phosphorus produced.
