Explanation:
One of the brightest comets of the 20th century was Comet Hyakutake, which passed close to the sun in early 1996. The orbital period of this comet is estimated to be about 30000 years.
Find the semi-major axis of this comet's orbit
The semi-major axis of Comet Hyakutake's orbit is approximately 88,000 AU.
We can use Kepler's third law to relate the orbital period of a comet to the semi-major axis of its orbit:
T^2 = (4π²/GM) a³
where T is the orbital period, G is the gravitational constant, M is the mass of the sun, and a is the semi-major axis of the comet's orbit.
We can rearrange this equation to solve for a:
a = [T² (GM) / 4²]\(^(1/3)\)
Plugging in the values given:
T = 30,000 years
G = 6.6743 × 10⁻¹¹ m³ kg⁻¹ s⁻² (gravitational constant)
M = 1.989 × 10³⁰ kg (mass of the sun)
a = [30,000² (6.6743 × 10⁻¹¹× 1.989 × 10³⁰) / 4π²\(]^(1/3)\)
a ≈ 88,000 astronomical units (AU)
Therefore, the semi-major axis of Comet Hyakutake's orbit is approximately 88,000 AU.

What push factors do you think force many people from Syria to flee?
Violence: Since the start of the civil conflict, about 13,000 children have died or suffered injuries.
Infrastructure that has collapsed includes hospitals, clinics, schools, utilities, and water and sewage systems.
Who are Syrians?Generally, People often leave conflict in the hopes of quickly returning. So they relocate close by—possibly to relatives or friends in a neighboring town or just over the border—so they can continue to monitor their properties and sources of income.
But many Syrians have given up on that optimism in the wake of the more than five-year battle. There is little hope for peace since their houses have been destroyed and their families ripped apart.
Thousands of individuals are now prepared to go far further in search of the protection they so urgently need since they have nothing left and their exile locations are becoming more overcrowded.
The situation within Syria has only become worse, with war escalating in every area and the country's services and economy essentially in ruins. This not only encourages new individuals to emigrate but also has a significant influence on those who have already fled to nearby nations.

What aspects of the Hopewell and Mississippian cultures defy traditional stereotypes of American Indians living north of Mexico? Explain what they are and why they are significant. 3. Why did Native Americans join the missions? What made the missions so destructive? What specific Spanish actions made the missions oppressive?
1. The various myths that Americans created about the mound builders were that the mound builders were not American Indians, but instead a lost tribe from another continent.
Some said that the mounds were built by European explorers from long before Columbus’s time. These myths were harmful for American Indians as they worked to erase the historical contributions of American Indians to North American culture.2. The Hopewell and Mississippian cultures defy traditional stereotypes of American Indians living north of Mexico in several ways. The Hopewell culture, for example, was a highly developed trading culture that constructed elaborate burial mounds.
The Mississippian culture was marked by large, walled cities with complex social and political structures. These cultures were significant as they showed that American Indians had complex societies with advanced technologies and that North America was not just a “wilderness” waiting to be tamed by Europeans.3. Native Americans joined the missions for various reasons, including the promise of food, clothing, and shelter.
However, the missions were ultimately destructive because they were designed to assimilate Native Americans into European culture and religion. The specific Spanish actions that made the missions oppressive include forced labor, beatings, and whippings, as well as the removal of Native American children from their families and communities to be raised in European-style boarding schools.

what is Mid-ocean ridges
Answer:
A mid-ocean ridge is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters and rises about two kilometers above the deepest portion of an ocean basin. This feature is where seafloor spreading takes place along a divergent plate boundary.
Explanation:
Answer:Mid-ocean ridges are a line of volcanic mountains under the oceans between the continents. As the oceanic plates are being pulled apart by the processes of plate tectonics, magma is formed from decompression melting in the mantle, and rises upward to fill in the gap that is created. Because this material solidifies and is still hot, it is buoyant and rises higher than the surrounding seafloor, creating the ridges. As it is pulled away from the spreading point by plate tectonics, it gradually cools, making it less buoyant; it gradually drops in elevation.

Most global warming is caused by carbon dioxide emissions from a few rich developed countries
Answer:
The statement is not true.
Explanation:
Global warming is a process that is occurring naturally, with or without human activity. This is not to say that humans don't have an impact, on contrary, the human activities have managed to add enough greenhouse gases in the atmosphere so that the process is speeded up, and that becomes very alarming because the changes are much faster.
Very often, the finger is pointed to the most developed countries in the world when it comes to greenhouse gas emissions like they are the only ones that contribute to it. This is far from true though. All of the well-developed countries, except for the US, have been investing heavily in environmentally friendly energy sources and have had a decrease in greenhouse emissions. On the other hand, countries like China, India, Indonesia, Pakistan, Nigeria, are all among the top polluters when it comes to greenhouse gases emissions. Now to be fair, the countries that are now well developed did a lot of harm in the past while they were developing, so it is hard to criticize the developing countries for wanting to become richer except if they are helped in sorting out the issue.
Which country was the first to industrialize? O A. England O
B. Russia
C. The United States O
D. China
Answer A England
Answer:
\( \boxed{ \boxed{ \underline{ \text{England}}}} \)
Explanation:
The industrial revolution was the period from the late 18th and early 19th century when England made revolutionary , dynamic and progressive changes in its industrialization. The significant changes in agriculture , manufacturing , mining , transportation and technology increased the production of goods efficiently and rapidly because the traditional manual works were transformed into power run machinery works. This turning point of the socio-economic development of human life is termed as industrial revolution in the world. It took place in England for the first time and gradually spread through Europe and even all over the world.
✑ \( \underline{ \text{Causes \: of \: industrial \: revolution \: from \: england}} : \)
Commercial classes were given more political and economic power and political stability was maintained in Britain after the glorious revolution. So, there was a favourable environment for those who wanted to invest in the commercial sectors.It had adequate natural resources like iron , coal , agriculture raw materials in the country and there could be supply of raw materials from the countries of Asia and Africa also.Due to its geographical situation surrounded by the sea and ocean , it would support overseas trade route.Less number of farmers had the hold in land ownership and large number of people were unemployed. Thus , there were sufficient labour forces which could be used in cheaper wages in the factories.Most of the people had hardworking , creative , positive and innovative approach to research and create the new types of works or inventions.✑ \( \underline{ \text{Condition \: of \: england \: before \: the \: industrial \: revolution}} : \)
England was an agricultural country before industrial revolution. Most of the population had to depend on agricultural occupations. Industrial activities were secondary occupations. Small and cottage industries of wool , cotton , coal , iron etc were operated in local levels. The goods were handmade with traditional spinning wheel and handloom. Women and children used to make thread while men used to weave clothes. When the Act of England 1700 AD banned the import of cotton clothes from other countries , the traditional method could not fulfill the increasing demand of clothes inside the county. The thread spun by 8 persons would be sufficient only for a person to weave clothes. Consequently, when the demands increased , the creative and innovative English introduces a series of inventions to address them.

10.8% of the population is 65 or older. Find the probability that the following number of persons selected at random from 50 people are 65 or older. The probability that all are 65 or older is..... The probability at most 2 are 65 or older is....
The probability that all 50 randomly selected people are 65 or older is extremely low. The probability at most 2 out of the 50 selected people are 65 or older is significantly higher.
The probability that all 50 randomly selected people are 65 or older is extremely low. To calculate the probability that all 50 randomly selected people are 65 or older, we need to consider the proportion of the population that is 65 or older. Given that 10.8% of the population is 65 or older, it means that out of every 100 people, approximately 10.8 are 65 or older.
Since we are selecting 50 people at random, the probability that the first person chosen is 65 or older is 10.8/100. The probability that the second person chosen is also 65 or older would then be 10.8/100 multiplied by the remaining proportion of the population that is 65 or older, which is (10.8-1)/99. This pattern continues for each subsequent person chosen.
Multiplying all these probabilities together gives us the probability that all 50 selected people are 65 or older. However, this value is extremely low because each individual probability is small. It is highly unlikely for all 50 randomly selected people to fall into the 65 or older age group.
The probability at most 2 out of the 50 selected people are 65 or older is significantly higher. To calculate this probability, we can consider the complementary event of the probability that all 50 selected people are 65 or older. In other words, we calculate the probability that 0, 1, or 2 out of the 50 selected people are 65 or older.
To calculate this, we can use the binomial probability formula. For each number of people (0, 1, and 2) being 65 or older, we calculate the probability of that specific outcome and sum them up. This probability is significantly higher than the probability of all 50 people being 65 or older since it takes into account multiple scenarios where fewer than 50 people fall into the 65 or older age group.
In conclusion, the probability that all 50 randomly selected people are 65 or older is extremely low, while the probability at most 2 out of the 50 selected people are 65 or older is significantly higher.

give one example of how diversity has caused tensions in a middle eastern nation
The Middle East is known for its complex history and diverse population. The tensions between various ethnic and religious groups in the region have been a major source of conflict for decades. One example of how diversity has caused tensions in a Middle Eastern nation is the case of Iraq.
Iraq is home to several ethnic and religious groups, including Arabs, Kurds, and Turkmens, as well as Shia and Sunni Muslims. The country has a long history of sectarian violence, and the tensions between these different groups have often boiled over into open conflict.
The most recent example of this is the rise of ISIS in Iraq. The group, which is composed mostly of Sunni Muslims, has carried out brutal attacks on Shia civilians and government forces. This has further exacerbated the tensions between Sunni and Shia Muslims in the country.
Moreover, the Kurdish population in Iraq has been demanding greater autonomy and even independence for many years. This has led to clashes with the central government and has created further divisions within the country.
In conclusion, the diversity of ethnic and religious groups in Iraq has caused tensions that have resulted in significant conflict. Unless the government addresses these underlying tensions, it is likely that Iraq will continue to experience violence and instability for the foreseeable future.

why is the mid atlantic ridge responsible for creating iceland
The Mid-Atlantic Ridge is responsible for creating Iceland due to the tectonic activity occurring along the ridge. The Mid-Atlantic Ridge is a divergent plate boundary where the Eurasian Plate and the North American Plate are moving away from each other. As the plates diverge, magma from the Earth's mantle rises to the surface, creating new crust and pushing the existing crust apart.
In the case of Iceland, it sits directly atop the Mid-Atlantic Ridge. The volcanic activity associated with the ridge has led to the formation of a series of underwater volcanoes along the ridge. Over time, these volcanic eruptions have built up layers of lava and volcanic material, gradually forming an island.
The continuous movement of the tectonic plates along the Mid-Atlantic Ridge causes the landmass to be pulled apart, resulting in the widening of the rift. This process leads to the creation of new crust and the formation of volcanic activity on the surface. The combination of volcanic eruptions and the spreading of the crust has contributed to the growth of Iceland over millions of years.
Iceland is known for its geothermal activity and numerous volcanoes, which are a direct result of its location on the Mid-Atlantic Ridge. The volcanic eruptions have played a crucial role in shaping the island's landscape and have contributed to the unique geological features found in Iceland.
In summary, the Mid-Atlantic Ridge creates Iceland through the ongoing tectonic activity of plate divergence, which results in volcanic eruptions and the accumulation of lava and volcanic material over time. This process has led to the formation and growth of the island as we know it today.
