Why are fossil fuels used so much today?

Answers

Answer 1
Fossil fuels store their energy in the chemical bonds that hold the hydrocarbon molecules together. That energy can stay trapped like that right up until the moment the hydrocarbons meet both heat and oxygen (O2).

Heat (from a match or spark) breaks the hydrocarbon and oxygen molecules apart, and then oxygen atoms react with the freed carbon and hydrogen atoms to give carbon dioxide (CO2) and water (H2O), and loads of energy as heat along the way.


combustion - burning fuel for energy
That extra heat is the key to fossil fuel's success. More heat energy is released when the new bonds form in CO2 and H2O than it took to break the original bonds in oxygen and the fuel. So once combustion starts, it's a runaway chain reaction giving off excess heat.

We've used the heat directly for cooking and warming, and indirectly to boil water for steam-powered turbines for electricity. The gases given off from burning fuels have driven pistons in internal combustion engines for more than a century.

Not only can we start a fire with a single spark, we can stop it by cutting the supply of fuel, air or heat, so it's a source of energy we can turn on and off as needed.

A controllable source of energy that has only two major downsides — finite supply and being the source of the CO2 that's driving climate change. No wonder fossil fuels have been such a hard habit for industrialised countries to kick.

Describe the relationship between the level of service and the price of a hotel room?

Answers

Answer:

The role of pricing on customer satisfaction has been largely ignored, however hospitality services are, for the most part produced by humans, and consequently, no two guest stays will be precisely alike.

However researches have been carried out suggesting that the variability in performance across different consumption experiences leads to increased uncertainty, and thus to decreased reliance on prior expectations, in such situation consumers tend to use price as a cue of performance expectations. Which makes it difficult to know customer satisfaction.

Meaning the relationship between the level of service and the price of hotel room is uncertain because know two human is alike.

Explanation:

Final answer:

The level of service and the price of a hotel room are directly related. Higher levels of service often mean higher prices, as the cost of providing these services is incorporated into the room price.

Explanation:

In general, the level of service and the price of a hotel room are directly proportional. This means that as the level of service increases, so does the price of the hotel room. For instance, a five-star hotel that provides high-end services such as 24-hour concierge, room service, and personal butlers will charge more for their rooms compared to a three-star hotel offering basic services like cleaning and breakfast. This is because the cost to provide these additional services is factored into the price of the room.

Plants absorb water from the soil through their roots. _______ of this water is used for photosynthesis; _______ of this water evaporates into the air through transpiration.
A.
None; all
B.
All; none
C.
Most; some
D.
Some; most

Answers

Answer: some,most

Explanation:

Final answer:

A small portion of the water absorbed by plants is used for photosynthesis, while the majority is lost through transpiration. The correct answer is D. Some; most.

Explanation:

Plants absorb water from the soil through their roots, but not all of this water is used directly for photosynthesis. Some of the water absorbed is utilized for photosynthesis and other metabolic functions within the plant, while most of it evaporates into the air through a process called transpiration. This process is essential for pulling more water up from the roots through the plant to the leaves, as the water vapor lost needs to be replenished. Therefore, the correct answer to the student's question would be D. Some; most.

What makes a source credible apex

Answers

A source is said to be credible when it is reliable consistently.

Explanation:

A source becomes credible when the source is reliable constantly , which means it is providing correct information constantly . When the information provided becomes true a trust factor starts working for that source and the receiver starts believing the information provided in that source.

In case of academic writing a source is said to be credible when it is providing unbiased information and along with proper evidence. While writing a research paper we always depend upon a credible source.

Final answer:

A source is considered credible when it is primarily fact-based, objective, and supported by evidence. The presence of a large number of advertisements may negatively impact source credibility. Expertise confirmation and aim transparency of the information provider also contribute to establishing credibility.

Explanation:

What makes a source credible is determined by its reliability, accuracy, and trustworthiness. A credible source provides information that is fact-based, objective, and corroborated by evidence. When a source is primarily fact-based, it's more likely to be credible as it presents verifiable information rather than opinions or speculations. Judging well the credibility of sources ensures the use of reputable, trustworthy evidence in research or argumentation.

However, if a source is opinion-based, it can significantly impact the view on its credibility since it may introduce bias and subjective viewpoints. Therefore, it is necessary to consider whether the source primarily presents facts or opinions. In assessing a source's credibility, one should also consider the influence of advertising. A large number of advertisements or certain types of advertising can affect the credibility of the source by suggesting potential bias or a commercial agenda.

For guidance on credible websites, verification from instructors, librarians, or other authoritative sources is important. Recognizing signs of expertise and understanding the background and aims of the information provider enhances the ability to determine credibility. Uncovering and verifying the original sources is a critical step in solidifying the credibility of the information presented in shorter newspaper articles or credible websites.

Using Credible Sources is an essential aspect of scholarly work and is integral to presenting convincing arguments and research. Tiered approaches to establishing credibility, such as tracing back to original texts and verifying the expertise of the authors, are strategies that should be employed.  

why is the location of water resources so important in southern and eastern africa

Answer: B

Explanation: It is B because the earth is pointing towards the sun.

In the Northern Hemisphere, summertime is at point X of Earth. Therefore, choice (B) is right.

What do you know about the Northern Hemisphere?

Just above the equator, trade winds blow from east to west. Due to the Coriolis effect, surface water is drawn along by the winds, forming currents that move westward.

The currents then turn to the right and move in a northerly direction. At roughly 30 degrees north latitude, a different set of winds, the westerlies, force the currents back to the east, creating a closed clockwise circle.

its surface is 60.7% water, as opposed to the Southern Hemisphere's 80.9% water, and it is home to 67.3% of the planet's land.

The Northern Hemisphere of the planet, which also includes nearly the whole continent of Asia, about two thirds of Africa, and a small portion of South America, is where the continents of Europe and North America are totally located.

Sometimes water scarcity is caused by human action. Describe an example of where this has occurred.

Answers

Answer:

Explanation:

Water scarcity already affects every continent. Around 1.2 billion people, or almost one-fifth of the world's population, live in areas of physical scarcity, and 500 million people are approaching this situation. Another 1.6 billion people, or almost one quarter of the world's population, face economic water shortage (where countries lack the necessary infrastructure to take water from rivers and aquifers).

Water scarcity is among the main problems to be faced by many societies and the World in the XXIst century. Water use has been growing at more than twice the rate of population increase in the last century, and, although there is no global water scarcity as such, an increasing number of regions are chronically short of water.

Water scarcity is both a natural and a human-made phenomenon. There is enough freshwater on the planet for seven billion people but it is distributed unevenly and too much of it is wasted, polluted and unsustainably managed.

Final answer:

Human action often contributes to water scarcity through over-extraction of groundwater, often in agriculture. Rapid population growth, urbanization and industrialization also increase the demand for fresh water supply. An example is Cape Town, where rapid urbanization and climate changes led to a severe water crisis.

Explanation:

Indeed, human action can significantly contribute to water scarcity. One common example can be seen in areas where there is excessive groundwater extraction. Particularly in agriculture, farmers may use sophisticated technology to pump water from aquifers more rapidly than it can be naturally replenished. This is known as over-extraction or 'mining' of water. Over time, this leads to a reduction in the water table, which in turn causes water scarcity. Moreover, population growth, urbanization and industrialization also increase the demand for freshwater and strain supplies. For instance, in cities like Cape Town, South Africa, rapid urbanization along with climate change had led to a severe water crisis. Thus, human activities are directly associated with water scarcity in many parts of the world.

how is white flight an example of the Pygmalion effect

Answers

Answer:

White flight is an example of Pygmalion effect because it stems from expectations of a white population for the new immigrants to behave a certain way which are then confirmed because of the said expectations.

Explanation:

Robert Rosenthal defined the Pygmalion effect as a self fulfilling prophecy, in that if a person or a group of people expect some behavior from others, they end up fitting into that behavior.

because the white population has a certain bias against the ethnically diverse people that moved into their living spaces in 50s and 60s, the tended to see those stereotypes more in their new neighbors. hence the phenomenon of white flight came about. the white population felt uncomfortable in their neighborhood because of their expectations and decided to move out.

Answer:

When looking north, you see stars appear to move in circles.

Explanation:

The motion of stars in northern hemisphere shows the circular motion that follows the path around the Polaris. As it takes 24 hours to complete one full circle, so during a night less than 12 hour, we see only certain part of path i.e. stars moving in an arc.And if you're facing north, they are moving from west to east.So depending upon the time of observation the stars may take the path of an arc or the full circle.

Answers

Answer:

The Koli believe they are deliberately being denied community services as a means to force them to move from their valuable waterfront property.

Explanation:

"The correct option is: The Koli believe they are being denied community services due to discrimination against their caste.

The Koli are a fishing community in India, and they have historically faced discrimination based on their caste. The belief that they are being deliberately denied community services is rooted in the perception that this discrimination is ongoing and manifests in various forms, including the withholding of services that are typically provided by local governments or other community organizations. This discrimination could be a strategy to marginalize the community and potentially force them to abandon their valuable waterfront property, which could be targeted for development or other economic interests. It is important to note that such beliefs may stem from historical and ongoing experiences of caste-based exclusion and inequality, which can affect access to essential services and resources. Addressing these concerns requires a commitment to social justice and equitable distribution of community services, ensuring that all groups, regardless of caste, have equal access to the support and resources they need."

d) None of the above

Answers

Answer:

dry, sandy, hot, maybe a desert

Final answer:

The correct option is a) Fine sands are generally deposited by wind. The absence of marine fossils and the presence of land animal fossils suggests that the area was dry, sandy land, such as a desert. This is the most likely condition under which layer C, a fine-grained sandstone with cross-bedding and land animal fossils but no marine fossils, formed.

Explanation:

Fine-grained sandstone, especially with features such as cross-bedding and land animal fossils, is indicative of terrestrial environments rather than marine. Cross-bedding occurs when wind or water flow shifts the orientation of sediments, which is common in desert dunes where winds are strong and unidirectional, creating angled layers. The presence of land animal fossils within the sediment further corroborates a terrestrial depositional environment, likely one where conditions for preservation were good, possibly due to rapid burial by the shifting sands typical in a desert scenario. The absence of marine fossils rules out a marine setting for this layer, despite the variety of depositional environments present in other sedimentary facies at the same geological time. Therefore, the conditions were those of a dry, sandy land area where wind played a significant role in sediment deposition.
