You use a straw to blow an air bubble into a milkshake. the bubble seems to stay in the shake. if the milkshake is like magma, and the air bubble is like water vapor trapped in the magma, what type of eruption would result?

Answers

If we consider the scenario where the milkshake is like magma and the air bubble is like water vapor trapped in the magma, then the type of eruption that would result is a explosive eruption.

In a volcanic eruption, when magma rises to the surface, pressure is released, and the gas bubbles in the magma expand. If the gas bubbles cannot escape and become trapped, they create a highly pressurized environment. This pressure builds up until it overcomes the strength of the rock, causing an explosive eruption.

Similarly, in the case of the milkshake, the straw blowing air into the shake creates a pocket of trapped air. The shake acts like a viscous fluid and is unable to release the trapped air. This creates a highly pressurized environment, similar to the trapped gas bubbles in the magma.

Therefore, if the milkshake is like magma and the air bubble is like water vapor trapped in the magma, then an explosive eruption would result.

Quadrilateral CDEF is a rhombus. What is the value of u?

Answers

After solving the value of u is 74°.

A quadrilateral is a four-sided polygon. It can be equilateral, meaning all sides are equal in length, or it can be a non-equilateral shape with four unequal sides.

After analyzing the diagram:

∠EFB = ∠CFB

∠CFB = 36

As we know that the sum of all angles in triangle is 180°. So

∠BCF = 180 - ∠FBC - ∠CFB

∠BCF = 180 - 90 - 36

∠BCF = 180 - 54

∠BCF = ∠BCD         (Angle is 90°)

what is greenhouse effect ?​

Answers

The greenhouse effect is a natural process that occurs on Earth that helps to regulate its temperature. It is the process by which certain gases, known as greenhouse gases, in the Earth's atmosphere trap the heat from the sun and prevent it from escaping back into space. The main greenhouse gases are carbon dioxide, methane, nitrous oxide, and water vapor.

When sunlight enters the Earth's atmosphere, some of it is reflected back into space by clouds and the Earth's surface, while the rest is absorbed by the Earth's surface and re-radiated as heat. The greenhouse gases in the atmosphere absorb and re-radiate this heat, causing the Earth's surface to warm up. This process is known as the greenhouse effect.

Without the greenhouse effect, the Earth's average temperature would be much colder than it is today, making it impossible for life to exist as we know it. However, human activities, such as the burning of fossil fuels and deforestation, have led to an increase in the concentration of greenhouse gases in the atmosphere, which has caused the Earth's temperature to rise at an alarming rate. This phenomenon is known as global warming and is causing significant changes to the Earth's climate and weather patterns.

flooding of low-lying coastal areas

Answers

An increase in sea level is a possible result of higher air temperatures caused by climate change.

Rise in sea level is one potential outcome of rising air temperatures brought on by climate change. Sea levels rise as a result of glaciers and ice caps melting more quickly as the air temperature rises. In addition to expanding, warmer water raises the sea level. Low lying coastal areas may experience flooding as a result which could be disastrous for the infrastructure and communities there.

Because rising sea levels can alter water salinity levels and have an impact on different species migration patterns, they can also have an impact on ecosystems. Higher temperatures are not likely to result in the freezing of the polar ice caps because this would require a significant and sustained cooling of the climate.

Connect Bangladesh/India/Colombia to Wallerstein's World's Systems Theory (Are they


Core, Semi-periphery or periphery and why) (Unit 7)

Answers

According to Wallerstein's World Systems Theory, countries are categorized into three groups: core, semi-periphery, and periphery. Core countries are highly industrialized and have strong economies, while periphery countries are less industrialized and have weaker economies. Semi-periphery countries fall somewhere in between.

Bangladesh, India, and Colombia can be connected to Wallerstein's World Systems Theory as follows:

1. Bangladesh: Bangladesh is considered a periphery country in Wallerstein's theory. Despite making some progress in recent years, the country still faces significant economic challenges, with a large portion of the population living in poverty. Its economy is heavily dependent on agriculture, and it relies on exports of garments and textiles to generate revenue. Overall, Bangladesh has not yet achieved the level of industrialization and economic development necessary to be classified as a semi-periphery or core country.

2. India: India is classified as a semi-periphery country in Wallerstein's theory. The country has made significant strides in recent years and has emerged as one of the world's largest economies. India has a diverse economy, with significant strengths in both services and manufacturing. However, it still faces some significant challenges, including widespread poverty and income inequality. India's position as a semi-periphery country reflects the fact that it has made progress towards becoming a core country, but still faces obstacles that prevent it from achieving that status.

3. Colombia: Colombia can be classified as a semi-periphery country under Wallerstein's theory. The country has a diversified economy that includes significant industries in oil, mining, and agriculture. However, it still faces significant challenges, including political instability and violence, which have hindered its economic development. Overall, Colombia has made progress towards becoming a core country, but still faces obstacles that prevent it from achieving that status.

In summary, Bangladesh is a periphery country, India is a semi-periphery country, and Colombia is also a semi-periphery country, according to Wallerstein's World Systems Theory.

Answers

You hear about a magnitude 8.0 earthquake on the news, and someone says it doesn't sound too bad since it's just one more than the 7.0 earthquake from last year. However, this is not the right way to think about the moment magnitude scale.

The moment magnitude scale is a logarithmic scale, meaning that each whole number increase represents a tenfold increase in the amplitude of ground motion and approximately 31.6 times more energy release. So, a magnitude 8.0 earthquake is not just one point more than a magnitude 7.0 earthquake, but rather ten times stronger in terms of ground motion and about 31.6 times more powerful in terms of energy release.

In conclusion, it is important to understand that the moment magnitude scale is logarithmic, and an increase in magnitude represents a significant increase in the earthquake's intensity and energy release. Therefore, an 8.0 magnitude earthquake is significantly more powerful than a 7.0 magnitude earthquake.

Two populations of squirrels are separated by a mountain range and would not be capable of interbreeding. This is an example of geographical isolation. The correct option is C.

When populations of a species are physically divided by a geographical barrier like a mountain range, river or canyon this is known as geographic isolation. The separation prevents gene exchange and intermarriage between the populations.

Genetic divergence among the populations can result in the evolution of various species, each of which is tailored to a particular environment over time. In this situation the physical barrier preventing the squirrels on either side of the mountain range from mating and having young prevents the development of distinct populations with different genetic traits.

why is the mercalli scale subject to uncertainty in determining the size of an earthquake? roman numerals, upon which this scale is based, are hard to use in mathematical equations. the mercalli scale is based on the amount of damage from an earthquake, which depends on many factors such as the strength of buildings, type of foundation, distance from the epicenter, and duration of shaking. the mercalli scale is directly related to the amount of energy released by the earthquake, which cannot be accurately measured with seismographs. the mercalli scale does not take into account the amount of damage from an earthquake, and therefore is not representative of the strength of ground shaking.

Answers

The mercalli scale is subject to uncertainty in determining the size of an earthquake as it is based on the amount of damage from an earthquake, which depends on many factors. The right answer is b.

Based on damage from observed earthquakes, the Mercalli Scale is used. From a scientific perspective, the Mercalli scale is based on observable data, which can be arbitrary, whereas the magnitude scale is established on seismic recordings. The magnitude scale is therefore regarded as being more accurate and scientifically more objective.

The quantity of shaking at a certain site is measured using intensity scales as the Rossi-Forel scale and the Modified Mercalli Scale. In the region of the epicentre where an earthquake occurs, shaking can range in intensity. As a result, depending on where you are, an earthquake's severity will change.

The function is E = 1.89x + 2.89y.

The following constraints are:

2x + y ≥ 10

x + 2y ≥ 8

x ≥ 0

y ≥ 0

The equations are

2x + y = 10 ...............(1)

x + 2y = 8 ...............(2)

Simplify the equation 1 and 2 to find the value of x and y.

Eliminate the y from the equation 1.

2x + y = 10

Subtract 2x on both side we get

y = 10 - 2x

Substitute the value of y in equation 2

x + 2(10 - 2x) = 8

Simplify

x + 20 - 4x = 8

20 - 3x = 8

Subtract 8 on both side, we get

12 - 3x = 0

Add 3x on both side, we get

3x = 12

Divide by 3 on both side, we get

x = 4

Substitute the value of x in y value.

y = 10 - 2(4)

y = 10 - 8

y = 2

Substitute the value of x and y in the function to find the maximum value of E.

E = 1.89x + 2.89y

Every 15 degree eastwards the time is 1 hour later so that when it is 2 pm in london, it is 8 pm in dhaka. at this time, what do the clocks in manila say 10 pm.

Based on the given information, we know that London is at 0 degrees longitude and Dhaka is at 90 degrees east longitude. Therefore, the time difference between London and Dhaka is 6 hours (15 degrees eastwards = 1 hour later, so 90 degrees eastwards = 6 hours later).

If it is 8 pm in Dhaka, then it would be 2 pm in London - this is the time difference we already know.

To find out what the time in Manila is, we need to know its longitude. Manila is located at approximately 120 degrees east longitude.

Every 15 degrees eastwards from London means an hour later, so we can calculate the time difference between London and Manila as follows:

- London to Manila is 120 degrees eastwards from London
- 120 divided by 15 is 8
- Therefore, the time difference between London and Manila is 8 hours

If it is 2 pm in London and the time difference between London and Manila is 8 hours, then the time in Manila would be 10 pm.

Therefore, the clocks in Manila would say 10 pm at this time.
