The process of combustion occurring without an open flame is called ________.
question 7 options:
The process of combustion occurring without an open flame is called Spontaneous combustion.
What is combustion?In the chemical process of combustion, an object quickly combines with oxygen to produce heat. The original substance is referred to as the fuel, and the oxygen's source as the oxidizer. Although it is typically a liquid for airplane propulsion, the fuel can be a solid, liquid, or gas.
A combustion reaction is a type of chemical reaction in which any combustible material reacts with an oxidizer to create an oxidized product. Fires and the release of heat energy are frequently present in combustion reactions.

Final answer:
The process of combustion without an open flame is referred to as 'the combustion reaction in a car engine,' and is an example of an adiabatic process occurring in the compression stroke of a gasoline engine.
Explanation:
The process of combustion occurring without an open flame is called the combustion reaction in a car engine. This type of combustion involves the rapid chemical combination of a substance with oxygen and is considered an adiabatic process because there is no possibility of heat conduction. This process is what happens in the compression stroke of a gasoline engine, and like other combustion reactions, it involves the production of heat. A common example of such a reaction is burning methane on a kitchen stove, which can be represented by the chemical equation CH₄ +₂O₂ → CO₂ + 2 H₂O + Heat.

____ are finely skilled handwork in media such as ceramics, glass, wood, metal, and fibers
Crafts encompass skilled workmanship in areas like ceramics, glass, wood, metal, and fibers, often involving high creativity and functional artistry. Craftsmen trained through apprenticeships to master their trade, creating works now recognized as Fine Craft or Craft Art. These traditions now merge with technology while maintaining their cultural relevance and artistic value.
Crafts refer to finely skilled handwork in mediums such as ceramics, glass, wood, metal, and fibers. These mechanical arts are often classified as the vocational trades that incorporate a high level of skill and creativity, such as metalworking, enameling, and stained glass creation. Craftsmen and artisans in various cultures, including Korean artists, were known for their abilities to work in multiple media, frequently borrowing techniques and decorative motifs across different materials to create intricate designs.
Throughout history, craftsmen were trained through lengthy apprenticeships, starting from an early age and culminating in the creation of a "masterpiece" to demonstrate their expertise. These skilled individuals might fashion jewelry, forge iron, or blow glass into unique forms, using their own designs. Fine Craft or Craft Art is a category today that recognizes the sophisticated blend of technique, functional purpose, and artistic expression found in these trades.
The value placed on crafts has evolved over time, with traditional studio crafts like textile arts being respected alongside classical Fine Arts. Many artists now merge traditional craftsmanship with modern technology, such as the digital programming of looms in fiber arts. The high level of workmanship and finish associated with crafts reflects a combination of utility, aesthetics, and creative innovation that is central to cultural expression and heritage.

37: a firm must decide which of 3 alternatives to adopt to expand its capacity. the firm wishes a minimum annual profit of 20% of the initial cost of each separable increment of investment. any money not invested in capacity expansion can be invested elsewhere for an annual yield of 20% of initial cost. your reasoning must include the ∆irr for each challenger-defender comparison.
As the firm requires a 20% profit on each increment of investment, we should examine the B- A increment of $200,000. (With only a 16% profit rate, C is unacceptable.)
Alt. Initial Cost Annual Profit Change in Cost Change in Profit Change in Profit Rate
A $100,000 $30,000
B $300,000 $66,000 $200,000 $36,000 18%
C $500,000 $80,000
With the alternative A it produces a 30% profit rate. The $200,000 increment of investment of B rather than A, that is, B- A, yield an 18% profit rate and is not acceptable. Thus it means Alternative B with an overall 22% profit rate can be considered as made up of Alternative A plus the B- A increment. Because the B-A increment is not acceptable, Alternative B should not be adopted.
Therefore the best investment of $300,000, for instance, would be Alternative A (annual profit = $30,000) plus $200,000 elsewhere (which is yielding 20% or $40,000 annually). At this combination firm yields a $70,000 profit, which is better than Alternative B profit of $66,000.

The texas instruments company has 9 percent coupon bonds on the market with seven years left to maturity. the bonds make annual payments. if the bond currently sells for $874.60, what is its ytm?
To Calculate YTM,
YTM = {C + (F-P)/n}/(F+P)/2
where C = coupon rate,
F = face value
P = price
n = no.of years
Therefore, YTM = {90+(1000-874.6)/7}/(1000+874.6)/2
=> 11.72%
Patients are given a drug treatment and then evaluated. symptoms either improve, degrade or remain the same with probabilities 0.4, 0.1, 0.5, respectively. assume that four independent patients are treated and let x and y denote the number of patients who improve or degrade. are x and y independent? calculate the covariance and the correlation between x and y.
Final answer:
The variables x and y, representing the number of patients who improve or degrade after drug treatment, respectively, are not independent. Calculating the covariance and correlation between x and y requires additional joint distribution data or specific outcomes, which are not provided.
Explanation:
Patients are given a drug treatment and then evaluated, with symptoms either improving, degrading, or remaining the same with probabilities of 0.4, 0.1, and 0.5, respectively. When evaluating the independence of two variables, x and y, which denote the number of patients who improve or degrade, respectively, we must consider the joint probability distribution of these two variables. Since the outcome for each patient is categorized into one of three mutually exclusive categories (improve, degrade, remain the same), an improvement for one patient influences the total number of possible degradations, and vice versa. Thus, x and y are not independent. To calculate the covariance between x and y, we recognize that because these events are not independent, the covariance is not zero. However, without specific probability distributions that detail the joint occurrence of x and y, we cannot directly calculate covariance without making assumptions or having further data. Generally, covariance is calculated as Cov(x,y) = E[(x-μx)(y-μy)] where E is the expectation, and μ represents the mean values of x and y, respectively. Correlation, often denoted as Pearson's r, measures the strength and direction of a linear relationship between two variables. Like covariance, without detailed joint distribution data or specific outcomes, we cannot provide a numerical calculation here. The correlation formula is ρ = Cov(x,y) / (σxσy), where σ represents the standard deviations of x and y. The correlation would provide insight into how changes in the number of patients who improve are linearly related to changes in the number of patients who degrade, pending the necessary data.

The Earned Income Tax Credit (EITC) helps low-income workers and their families by providing a tax credit that increases with earned income up to a certain point. To avoid the poverty trap, the EITC phases out slowly as earnings rise, encouraging continued employment.
Explanation:Earned Income Tax Credit (EITC) and the Poverty TrapThe Earned Income Tax Credit (EITC) is a crucial anti-poverty tool in the U.S. tax system designed to support low-income workers and to incentivize work. The credit increases with earned income up to a certain point, thus providing greater assistance to those with lower income and encouraging work. To address the issue of the poverty trap, where each additional dollar earned could lead to a nearly equivalent reduction in government support, the EITC is structured to phase out gradually. For a single parent with two children, there is no reduction in the EITC as earnings increase from $13,430 to $17,530. After crossing the $17,530 threshold, the credit decreases by 21.06 cents for every dollar earned, phasing out entirely at an income level of $46,227. This gradual phase-out reduces the potential disincentive to work that may occur with other types of government assistance which can be abruptly reduced.
In the specific scenario provided, Diane, a single taxpayer with two qualifying children, who has earned $17,700 in wages and $700 in dividend income in 2016, would still be within the range to receive the EITC.

Here is a quote from the article: "instead, these nonemployed workers tend to be those who have been left behind by the economic changes of the last generation. their jobs have been replaced by technology or have gone overseas, and they can no longer find work that pays as well." which type of unemployment does this quote describe
The quote is indicative of structural unemployment, where changes in the economy such as technology and outsourcing make certain jobs obsolete and workers' skills are no longer in demand. Affected workers face long-term unemployment and the need for skill redevelopment or industry change.
The quote describes a scenario where workers have become unemployed due to economic changes, such as technological advances and globalization, which have resulted in their jobs being automated or moved overseas. This situation is an example of structural unemployment, which is a form of unemployment resulting from industrial reorganization, typically due to technological change, where skills that workers have are no longer in demand. Structural unemployment is often long-term and requires workers to acquire new skills or change industries to find employment.
In the wake of economic downturns, such as the one that began in 2008, high unemployment rates often reflect structural issues within the economy. For instance, individuals who have lost their manufacturing positions may find themselves unqualified for new economy jobs due to a mismatch between the available jobs and their skills, which perpetuates a cycle of cyclical poverty.
The evolution toward a more technology-driven economy creates a gap where certain workers' skills become outdated, and their jobs are not easily transferrable to emerging industries without significant retraining. This shift can lead to a large pool of structurally unemployed individuals facing limited job prospects and potentially long periods of unemployment, particularly in the face of international competition and industry-specific skill sets.
