Exercise 12.5 (Fiber-preserving maps). Given two maps : E→M and ': E' → M, check that a map : E→ E' is fiber-preserving if and only if the diagram E E' M commutes. T

Answers

Answer 1

Let us take E→M and E′→M two maps. Then we need to prove that a map E→E′ is fiber-preserving if and only if the diagram E E′ M commutes. This proof will be done through the following steps:Given two smooth fiber bundles (E,π,M) and (E′,π′,M′) of the same dimension, and a smooth map ƒ:E→E′.

Let ƒ be a fiber-preserving map, that is, a map that preserves the fibers. Let us define φ and ψ to be the projections of E and E′ onto M, and M′, respectively. Thus we have the following commutative diagrams:Where ϕ:E→M is the projection of E onto M and ψ:E′→M′ is the projection of E′ onto M′.

Then for any point x∈M, let y∈π⁻¹(x), so ϕ(y)=x, that is, y is in the fiber over x. Since ƒ is fiber-preserving, it maps the fiber over x to the fiber over ƒ(x), which contains an element z∈π′⁻¹(ƒ(x)). Thus ƒ(y)=z. Therefore, we can define a map g:M→M′ by g(x)=ψ(z) for any y∈π⁻¹(x).Then, we have the following commutative diagram:Therefore, we see that if ƒ is a fiber-preserving map, then g is well-defined and smooth.

Moreover, the diagram E E′ M commutes, that is, ψ∘ƒ= g∘ϕ.Now, let g:M→M′ be a smooth map such that the diagram E E′ M commutes. We need to prove that ƒ is a fiber-preserving map. Let x∈M and y∈π⁻¹(x). Then ƒ(y)∈E′ and ϕ(y)=x. Since the diagram commutes, we have that ψ(ƒ(y))=g(x).Thus, we have ϕ(y)=x, ψ(ƒ(y))=g(x), and g is a smooth map.

Thus there exists z∈π′⁻¹(ƒ(x)) such that ψ(z)=g(x).Since the diagram commutes, we have that ƒ(y)=z. Therefore, ƒ is a fiber-preserving map.

Thus, we have proved that a map E→E′ is fiber-preserving if and only if the diagram E E′ M commutes.

1. a) In relation to regional metamorphism, what are "tectonic forces" and what creates them?

b). Why does regional metamorphism always accompany an "orogeny"?

c). What is the significance of "pelitic" rocks to classic "Barrovian" metamorphism?

Answers

a. Tectonic forces are the forces caused by movements in the Earth's crust. They create the pressure and heat that leads to metamorphism. When rocks are buried and heated and compressed at depth, they undergo a change in mineral composition and texture, resulting in metamorphism.

These forces can be caused by plate tectonics, such as when two plates collide, or by mountain building processes, such as when mountains are formed through folding and faulting. b. Regional metamorphism always accompanies an orogeny because an orogeny involves the formation of mountains, which is usually caused by the collision of two tectonic plates. The pressure and heat generated by the collision lead to regional metamorphism of the rocks in the area. The rocks become deformed and undergo changes in mineral composition and texture as a result of the pressure and heat. c. Pelitic rocks are important to classic Barrovian metamorphism because they are the type of rocks that are most commonly found in the metamorphic belts associated with this type of metamorphism. Pelitic rocks are made up of clay minerals and other fine-grained materials that are easily deformed under heat and pressure. When they are subjected to regional metamorphism, they undergo changes in mineral composition and texture that are characteristic of classic Barrovian metamorphism. Pelitic rocks are also important because they are used to define the different zones of Barrovian metamorphism.

The Lookout Mountain is a complex formation that has been shaped by geologic forces over millions of years. Its three main units are Chickamauga Limestone, Sand Mountain Sandstone, and Lookout Mountain Limestone, and each of these units has different lithologies and controls on the physical and biological landscape of Cloudland Canyon.

The Lookout Mountain is one of the world's most beautiful and geologically diverse mountain ranges. It is in the extreme northwest of Georgia and extends from Chattanooga, Tennessee, to Gadsden, Alabama.The Lookout Mountain is divided into three main geologic units that form a “layer cake” or stratigraphy as follows:The bottom unit, known as the Chickamauga Limestone, is the lowest unit. It is formed of marine limestone rock with fossils and is exposed in the bottom of the canyon. The lithology of this rock type is calcareous, which means it contains calcium carbonate as the main mineral.The middle unit is the Sand Mountain Sandstone, which is an extremely resistant sandstone formation. The lithology of this rock type is siliciclastic, which means it is composed of silicate minerals such as quartz and feldspar. This layer is responsible for creating the stunning cliffs and rock formations of the canyon.The uppermost unit is the Lookout Mountain Limestone, which is a pure marine limestone formation. The lithology of this rock type is calcareous and it is characterized by fossil fragments. It is the main formation responsible for the creation of the Cloudland Canyon’s iconic rock formations.The three units have different controls on the physical and biological landscape of Cloudland Canyon. The Chickamauga Limestone formation is easily eroded by water. It makes up the canyon floor and creates the waterfalls and pools of the canyon. The Sand Mountain Sandstone is a hard, resistant formation that resists erosion. It forms the canyon walls and creates the steep cliffs and canyons of the canyon. The Lookout Mountain Limestone, which is the purest limestone formation of the three, creates unique habitats for plants and animals, such as caves and sinkholes.

b) When driving through a River Valley area, it is not uncommon to see a veil of clouds along the slopes of Mountains even though the skies are clear. How do these clouds form?

Answers

The movement of tectonic plates is responsible for several changes on the Earth's surface, and this affects the climate. These changes are responsible for the formation of mountains, and as moist air is forced up their slopes, it leads to the formation of orographic clouds.

a)Continental drifts greatly affected the climate. Explanation of three mechanisms of the influences caused by the movement of tectonic plates:The movement of tectonic plates was responsible for the separation of Pangea, which then led to the formation of modern-day continents. It was during this movement that the climate was affected in several ways.The first mechanism of influence caused by the movement of tectonic plates on climate is changes in the positions of the continents and their corresponding landmasses. This has led to a difference in climate from one region to another. Some areas now have more arid climates, while others are much more humid than they were before.The second mechanism of influence caused by the movement of tectonic plates on climate is the way in which they affect ocean currents. The ocean currents are influenced by the temperature of the water in the oceans. The movement of tectonic plates affects the temperature of the water, which can have an impact on the strength and direction of ocean currents.The third mechanism of influence caused by the movement of tectonic plates on climate is volcanic activity. Volcanic activity can be caused by the movement of tectonic plates, which can lead to changes in the composition of the atmosphere. For instance, volcanic eruptions can lead to an increase in the amount of carbon dioxide and sulfur dioxide in the atmosphere. These are known greenhouse gases that can lead to the warming of the Earth's atmosphere.

b) When driving through a River Valley area, it is not uncommon to see a veil of clouds along the slopes of Mountains even though the skies are clear. How do these clouds form?The clouds that are seen along the slopes of mountains even though the skies are clear are known as orographic clouds. These clouds are formed due to the presence of moist air that has been forced up the slopes of the mountains. The moist air is cooled as it rises, and the water vapor it contains then condenses into clouds. The process of water vapor turning into water droplets is known as condensation. This results in the formation of clouds. The formation of orographic clouds is also influenced by the temperature of the air. As air rises, it cools down and can reach its dew point, which is the temperature at which it can no longer hold the water vapor. When the temperature reaches the dew point, the water vapor then condenses into water droplets and forms clouds.

Which of the following is NOT a method by which to achieve more sustainable use of nonrenewable mineral resources?
a. Reduce waste, recycle, and reuse.
b. Slow population growth.
c. Find substitutes.
d. Reduce mining subsidies.
e. Remove minerals faster so the mining

Answers

Answer:

reduce waste recycle and reuse

The option that is NOT a method to achieve more sustainable use of nonrenewable mineral resources is e. Remove minerals faster so the mining. This approach goes against the principles of sustainability and responsible resource management.

Achieving more sustainable use of nonrenewable mineral resources requires a shift towards conservation and efficient utilization of existing resources. Let's discuss the other options and why they contribute to sustainability:

a. Reduce waste, recycle, and reuse: This method focuses on minimizing resource waste by promoting practices such as recycling and reusing materials. By doing so, the demand for new mineral extraction is reduced, leading to a more sustainable use of resources.

b. Slow population growth: Population growth directly impacts resource consumption. Slowing population growth can help alleviate the strain on nonrenewable resources and reduce the demand for minerals. It allows for more effective resource management and a better chance of long-term sustainability.

c. Find substitutes: Finding substitutes for nonrenewable minerals can help reduce reliance on them. By developing alternative materials or technologies that serve the same purpose without depleting nonrenewable resources, we can mitigate the environmental and social impacts associated with mining.

d. Reduce mining subsidies: Mining subsidies are financial incentives provided to the mining industry, which can lead to increased extraction of minerals. By reducing these subsidies, governments can encourage more sustainable practices and discourage excessive mining that can deplete resources and harm the environment.

These methods aim to promote responsible resource management, reduce resource consumption, and minimize environmental impacts. However, option e, which suggests removing minerals faster through increased mining, contradicts the principles of sustainability. Rapid extraction without proper consideration of environmental consequences and long-term resource availability can lead to resource depletion, habitat destruction, and other negative impacts.

Therefore, option e is not a method for achieving more sustainable use of nonrenewable mineral resources, while the other options contribute to sustainable resource management and conservation.

Answers

Power imbalances can have a negative impact on individuals, and societies need a balance between central leadership and individual freedom to thrive. Protests can be effective, but they also have their limitations and can sometimes lead to violence.

One of the situations where an individual may feel that power is imposed upon them is in the workplace. When there is a power imbalance, such as when a boss has more power than their employee, the boss can impose their will on the employee, whether that is through intimidation, harassment or controlling behaviour. This can lead to feelings of helplessness, fear, and frustration.In terms of societies, it is a matter of balance. Central leadership can provide direction and stability, but too much centralization can lead to tyranny and suppression of individual freedoms. On the other hand, individuals acting freely can lead to innovation and creativity, but too much freedom can lead to chaos and anarchy. Therefore, a balance between central leadership and individual freedom is necessary for a robust society.Protests can be an effective way to challenge authority because they bring attention to the issues at hand and can put pressure on those in power to make changes.

An parcel at sea level has a Temperature of 15 degrees Celsius. What is its Saturation Mixing Ratio?

O 1.8 g/kg
O 5.4 g/kg
O 10.6 g/kg
O 20.0 g/kg

Answers

To determine the saturation mixing ratio of the parcel at sea level with a temperature of 15 degrees Celsius, we can use the Clausius-Clapeyron equation. The saturation mixing ratio represents the maximum amount of water vapor that the air can hold at a specific temperature.

The saturation mixing ratio is given by:

[tex]W_s = (ε * e_s) / (P - e_s)[/tex]

where:

W_s is the saturation mixing ratio

ε is the ratio of the molecular weight of water vapor to the molecular weight of dry air (approximately 0.622)

e_s is the saturation vapor pressure at the given temperature

P is the total atmospheric pressure

To calculate the saturation vapor pressure at 15 degrees Celsius, we can use the Magnus-Tetens formula:

[tex]e_s = 6.112 * exp((17.67 * T) / (T + 243.5))[/tex]

where:

T is the temperature in degrees Celsius

Let's substitute the values and calculate the saturation mixing ratio:

T = 15 degrees Celsius

P = Total atmospheric pressure (which is not given in the question)

First, let's calculate the saturation vapor pressure at 15 degrees Celsius:

[tex]e_s = 6.112 * exp((17.67 * 15) / (15 + 243.5))\\e_s ≈ 17.3896 hPa[/tex](rounded to four decimal places)

Now, we can calculate the saturation mixing ratio:

[tex]W_s = (0.622 * e_s) / (P - e_s)[/tex]

Since the total atmospheric pressure (P) is not given, we cannot determine the exact saturation mixing ratio.

3) Which side of a mountain range will experience wet conditions as a result of air flow?

Answers

The side of a mountain range that will experience wet conditions as a result of air flow is the windward side. As air moves up and over a mountain range, it cools down and releases water as precipitation.

Windward side: It refers to the direction from which the wind is blowing and is the side of a mountain range that faces the prevailing wind. As air is forced to rise over the mountains, it cools and expands, leading to a drop in temperature and an increase in atmospheric pressure.

The decrease in temperature and pressure causes the water vapor in the air to condense and fall as precipitation, resulting in wet conditions. Leeward side: It is the side of the mountain range away from the prevailing wind. As the air descends, it compresses and heats up, resulting in warmer and drier conditions. It is sometimes referred to as the "rain shadow" because the prevailing winds absorb the moisture, resulting in dry conditions. Overall, the windward side of the mountain range will experience wet conditions as a result of airflow. The air is cooled as it rises over the mountains, leading to precipitation.

Reports from the Curiosity rover showed that the escape velocity for gas molecules on the newly discovered planet is 9 km/s, and the gases present are carbon dioxide and nitrogen. Is this information enough to determine if the atmosphere of the planet is suitable for human life? Why or why not? Your answer should include the factors affecting the ability of the planet to retain an atmosphere and how temperature affects velocity.

Answers

No, the provided information is not enough to determine if the atmosphere of the planet is suitable for human life.

The escape velocity of gas molecules is only one factor in determining whether an atmosphere is suitable for human life. Other crucial factors include the composition of the atmosphere, atmospheric pressure, presence of essential gases (such as oxygen), temperature, and the ability of the planet to retain its atmosphere. Escape velocity refers to the minimum velocity required for a gas molecule to escape a planet's gravitational pull. However, it does not provide information about the overall composition and stability of the atmosphere. For an atmosphere to support human life, it would typically require a suitable combination of gases, including oxygen, to sustain respiration. Additionally, factors such as atmospheric pressure and temperature are crucial, as they affect the overall habitability of a planet. Temperature plays a significant role in determining the velocity of gas molecules. Higher temperatures generally result in higher velocities, which can increase the likelihood of gas molecules escaping the planet's gravitational pull. Therefore, the temperature conditions of the planet are important considerations when assessing the suitability of the atmosphere for human life. In conclusion, while the escape velocity of gas molecules provides some information about the potential for gas escape, it is insufficient to determine the overall suitability of the atmosphere for human life. A comprehensive analysis of various factors, including composition, pressure, temperature, and stability, is necessary to assess habitability.

Explain the following types of tourism multipliers:

- taxes

- investment

- employment

Answers

Taxes Multiplier: The taxes multiplier refers to the additional tax revenue generated by the tourism industry. As tourism activities increase, such as visitor spending or accommodation bookings, governments collect more taxes, such as sales taxes or hotel taxes. The taxes multiplier quantifies the indirect economic impact on government finances resulting from increased tourism-related tax revenues.

Investment Multiplier: The investment multiplier focuses on the economic impact of tourism-related investments. When investments are made in tourism infrastructure, such as hotels, resorts, or attractions, it creates a ripple effect in the economy. These investments generate direct employment opportunities, as well as indirect and induced effects through the purchasing of goods and services from local suppliers, thereby stimulating economic activity in the region.

Employment Multiplier: The employment multiplier measures the job creation impact of the tourism industry. Tourism creates direct employment in areas such as accommodation, food services, and transportation. It also leads to indirect employment through the supply chain, as businesses that provide goods and services to the tourism industry experience increased demand. Additionally, induced employment is generated by the spending of tourism employees and those employed indirectly, further stimulating economic activity and job creation in the destination.

♥️ [tex]\large{\textcolor{red}{\underline{\mathcal{SUMIT\:\:ROY\:\:(:\:\:}}}}[/tex]

The tourism multiplier is an economic indicator that measures tourism's indirect and induced impact on the economy. Three important types of tourism multipliers are as follows:

1 Taxes- Taxes refer to revenues generated by governments through various taxes levied on tourism-related activities. When tourists spend money on accommodation, meals, transportation, and other goods and services, they contribute to the local tax base. The government can use this tax revenue to fund public services and infrastructure development. The tax multiplier measures the additional economic effect that occurs when tax revenue circulates within the economy, leading to further job creation, investment and economic growth.

2 Investment- Tourism can stimulate investment in infrastructure development, such as building hotels, resorts, airports, roads and other tourist facilities. The investment multiple captures the indirect and induced effects of that capital investment. Building new tourism infrastructure requires inputs such as building materials, labor and services that generate economic activity in other sectors, leading to more business opportunities, job creation and increased income for individuals and businesses.

3 Employment- The employment multiplier measures tourism's indirect and induced employment effects. Tourism significantly impacts job creation, both directly in tourism-related industries (e.g., hotels, restaurants and tour operators) and indirectly in sectors that supply goods and services to the tourism industry (e.g., agriculture, transport and retail trade).

An earthquake's energy release is often referred to as A. Unit B. Magnitude C. Direction D. Scale

Answers

An earthquake's energy release is often referred to as magnitude.

An earthquake's energy release is often referred to as magnitude. It is a measure of the total amount of energy released during an earthquake. This energy is released in the form of seismic waves that travel through the earth's crust and cause the ground to shake. The magnitude of an earthquake is determined using seismographs, which record the amplitude and duration of the seismic waves. The most commonly used magnitude scale is the Richter scale, which ranges from 0 to 10. Each increase of one unit on the Richter scale represents a tenfold increase in the amplitude of the seismic waves.

Therefore, the correct option is B. Magnitude. An earthquake's energy release is often referred to as magnitude.

which of the following best describes how hot towers can intensify a hurricane?

Answers

Hot towers can intensify a hurricane by releasing latent heat into the environment. The hot towers are thunderstorms with high vertical extent, and their presence in a hurricane can help intensify the storm.

The thunderstorms in a hot tower are caused by the warm moist air in the eyewall rising and converging with the colder drier air in the upper levels. The rising warm air carries the water vapor and other gases, which condense to form cloud droplets. During this process, the water vapor releases latent heat, which is absorbed by the surrounding air. This heat transfer is called the latent heat flux, and it can release a tremendous amount of energy into the environment.

The release of latent heat can occur at different heights in the atmosphere, but the hot towers are the most powerful convective cells in a hurricane. The hot towers can release energy at a rate of 10^13 watts, which is equivalent to the output of a small nuclear bomb. This heat release can create an area of low pressure in the surrounding atmosphere, which can cause air to flow into the center of the hurricane. This inflow of air can provide the hurricane with a new source of energy, which can help it intensify.

The sociocultural standard of beauty is synonymous with a level of thinness that is unobtainable for most women, and the substantial and growing discrepancy between females' perceptions of the ideal body size and the body size of the average women is well-documented. As women become fixated with trying to attain this unrealistic ideal point, many of them are engaging in a variety of unhealthy behaviors that are illustrated by a number of alarming trends. For example, the National Eating Disorders Association reports a continuous increase in eating disorders (for example, anorexia and bulimia) in the last decade. Additionally, the number of consumers having cosmetic procedures performed continues to grow, with women representing over 90 percent of the total. Recently, the American Medical Association asked the ad industry to stop photo-shopping photographs because of the unhealthy messages they promote. Some brands, such as Aerie, and most recently CVS, have stopped the use of airbrushing. However, the media continues to predominantly feature models with the thin-ideal.Interestingly, research demonstrates that although idealized imagery negatively impacts young women's self-esteem and body satisfaction, they prefer the idealized ads to untouched ads that feature "real" or plus-size models. My research with Dan Rice and Amanda Mabry-Flynn used theory rooted in social comparison and goal attainability to examine ads that featured thin versus plus-size models in advertisements for weight loss products. We replicated prior work that shows women prefer the ads that feature the thin-model, despite the fact that the thin model resulted in lower self-esteem and less favorable self-perceptions. Further, we found that women's perceptions of achieving their goal of weight loss mitigated these negative effects; when young women felt they could achieve their goal, their self-perceptions were not lower than women who were exposed to a plus-size model. Additionally, shame explains these effects. We found that women who believe the goal is attainable are able to overcome feelings of shame, whereas women who view the goal as unattainable experience shame, which then results in lower self-esteem and self-perceptions.These findings offer interesting implications from both a marketing and public policy perspective. Brands who manufacture self-improvement products (e.g., weight loss, anti-aging) are in an interesting position. Since females are often seeking improvement and such goals are often highlighted in image-based advertisements that feature thin models, arguably, these types of effects are likely robust in the marketplace. Should marketers attempt to alleviate this discrepancy? If so, our research indicates marketers have a straightforward solution: communicate the attainability of the goal. That is, explain that by using the product, consumers can achieve the goals conveyed in the advertisement. This attainability claim still produces favorable effects for the brandso the brand benefits, but it also protects self-perceptions potentially making the ads less destructive to female consumers. However, this work also demonstrates the power of product claims and deceptive advertising. It is cautioned that these claims need to be truly attainable and marketers, as per specific legal guidelines required in all advertising, need to be able to substantiate their claims.Part 2Should photoshopping be regulated in the United States?

There are currently two locations, each with its own manager. Heramb Patel is the Manager with 10 years retail experience and he is very well-liked by all the employees. They were grateful when Heramb spoke to the owner, Susan, about a health plan and they enjoyed the social activities The Bean Shop provided for the whole team. He knew most of the employees by name and he spent much of every day visiting with staff and asking them how they are doing,Heramb felt it was important to treat employees well so they would have a sense of loyalty to the small, yet growing, coffee shop. He always tried to avoid seasonal layoffs, knowing the small business couldnt afford to lose great baristas. The employees knew if they had a problem, Heramb was always there to help them. For example, when one employee had a scheduling problem with final school exams, Hermab quickly amended the schedule. Heramb really felt that if you tried to accommodate and help everyone, they wouldnt need close supervision or reminders to get the work done. He applied the same logic to the shift leads; he left them alone to run the shop floor. He did not set objectives or sales targets and he never asked the team to make improvement plans. If everyone was happy, he was happy, and the business was just fine.Herambs locations had the lowest staff turnover of the two locations, but overall gross revenues were lower. When Susan had to make a call to streamline staff and amalgamate her managers, Heramb was let go and Cassandra Jones was asked to manage both locations.Cassandra had the reputation who could get things done and drive sales, and she quickly began making changes. All staff activities were cut from the operations budget, and discussions were ceased about health programs and other benefits. If the salary was not good enough for the staff members, then they could find a new place of employment.Cassandra implemented daily and weekly sales targets for each location and posted "competition boards" to see which location could win. She also implemented a check-in timecard system. Each employee had to check-in and out every time they took a break or left shift. Cassandra felt she needed to monitor every minute of their shift. If employees asked questions or had concerns about the schedule, she quickly dismissed conversations. She also wanted the Shift Leads to write up weekly status reports on every employee. The Leads started to feel buried in paperwork when they really wanted to inspire and motivate the staff when they were at work. Cassandra didnt hesitate to let people go and hire new people as required. Staff turnover skyrocketed under the new structure.Susan wanted to expand locations and had plans for at least two more locations. However, she quickly realized that her employment costs were higher than they ever were before. Staff who work with Heramb struggled with Cassandras new leadership style and left in search of new work environments. Susan was nervous about her expansion plans nowThe Bean Shop had become an unpleasant place to work.Question:If you were Susan, what would you do?
