Why have researchers had difficulty finding a precise number of people that lived in the Americas?

Answers

Answer 1

Answer: Because over the years many people have migrated to America.

Explanation: For the past century, archaeologists have generally agreed that humans arrived in the Americas 12,000 - 15,000 years ago but now this turns out to be quite erroneous. Instead, new excavations show that humans arrived in the Americas more than 30,000 years ago which is why the certain number cannot be confirmed.

Answers

The correct option is D, Air pressure.The given image shows a diagram explaining a concept of "Air pressure."

Therefore, the correct option is D, Air pressure.What is Air Pressure?Air pressure is defined as the amount of pressure exerted by the weight of air molecules on a given surface. It is also known as atmospheric pressure. The pressure at sea level is roughly 14.7 psi (pounds per square inch) or 101.3 kPa (kilopascals).As air rises, the weight of the air column above decreases, causing a drop in air pressure.

Similarly, as we move up in altitude, air pressure decreases since there is less air above the given point to exert weight. Temperature, altitude, and air density all impact air pressure in various ways.

Safety needs refer to the need for a secure and stable environment, including physical safety, financial security, and protection from harm.

Meeting these two basic needs is essential for individuals to move up the hierarchy and achieve higher-level needs such as love and belonging, esteem, and self-actualization. One of the two basic (lower) levels in Maslow's hierarchy of needs is "physiological needs." These needs include essential elements for survival such as air, water, food, shelter, and clothing.

After a recent rainy season, a number of the communities in a western state suffered flooding and mudslides. A study commissioned by the state legislature determined that the extensive removal of a certain plant from hillsides within the state contributed significantly to the flooding and mudslides. The plant had an extensive root system that helped hold hillside soil in place, and it was being rapidly removed because its roots had recently gained national favor as a powerful herbal remedy. As a result, the legislature passed a statute prohibiting the removal of more than 50% of such plants from any hillside within the state. A landowner within the state challenged the statute under the Takings Clause of the Fifth Amendment, alleging that he had regularly harvested substantially more than 50% of the plants from his property and needed to do the same this year to meet the demand for the root. Is he likely to prevail in his challenge?

Answers

Answer:

Explanation:

The fift amendment is a law put in place by the united states it includes a due process clause and it statesthat no person shall "be deprived of life, liberty, or property, without due process of law.

The landowner can prevail going by the rule of law he has the right to make his intention known about his plant because it is his source of livelihood and the law says no one should be deprived of it.

He will prevail with the challenge because law was already made and going by it gives him more confident that he is not going wrong because rules, laws are to be followed to guide our actions and in-actions.

The results of a survey show that the percent of adults in a certain town who want to change the name of the town is in the interval [0.78 ,0.86]
What is the point estimate for the percent who want to change the town’s name?
What is the poll’s margin of error?
Do you think the town is most likely to change its name? Why?

Answers

The point estimate for the percent who want to change the town's name would be the midpoint of the interval. Therefore, the point estimate is (0.78 + 0.86) / 2 = 0.82, or 82%.

To determine the poll's margin of error, we need to calculate the half-width of the interval. The half-width is half of the difference between the upper and lower bounds. Therefore, the half-width is (0.86 - 0.78) / 2 = 0.04, or 4%.

The margin of error can be obtained by multiplying the half-width by 2. Thus, the margin of error for this poll is 2% (0.04 * 100).

As for whether the town is most likely to change its name, the poll results alone do not provide enough information to make a definitive conclusion.

Answers

The answer should be A

5 Which of the following is considered an advantage of federalism? А Federal government has the authority to impose federal grants and unfunded mandates. B State and local governments have latitude to address policy based on their specific needs. CO It encourages race-to-the-bottom dynamics. DO It limits the presence of dissenting opinion to policy.

Answers

The correct answer is:

B. State and local governments have latitude to address policy based on their specific needs.

An advantage of federalism is that it allows state and local governments to have autonomy and flexibility in addressing policy issues according to their specific needs. In a federal system, power and decision-making authority are shared between the central (federal) government and regional (state or local) governments. This allows for policy-making and implementation at different levels of government, enabling tailored solutions and adaptations to local circumstances.

Option A is not an advantage of federalism. While the federal government can impose federal grants and unfunded mandates, it is not necessarily viewed as an advantage. It can create financial burdens and constraints on state and local governments.

Option C is not an advantage of federalism. "Race-to-the-bottom" dynamics refer to a situation where states or regions compete to lower standards or regulations in order to attract businesses or investments. This can have negative consequences in terms of reduced environmental protections or workers' rights.

Option D is not an advantage of federalism. In a federal system, dissenting opinions and diverse perspectives are more likely to be accommodated and represented, as decision-making is distributed across different levels of government. It allows for a broader range of voices and viewpoints to influence policy outcomes.

Therefore, the true statement is B. State and local governments have latitude to address policy based on their specific needs.

how does distance affect attenuation? how does distance affect impedance?

Answers

Attenuation increases with distance due to factors like absorption, scattering, and reflection. Impedance increases with distance in transmission lines due to the increased resistance.

Distance can have significant impacts on both attenuation and impedance in various contexts. Attenuation refers to the reduction in signal strength or energy as it travels through a medium, such as air or a cable. The amount of attenuation experienced by a signal depends on several factors, including the frequency of the signal, the characteristics of the medium, and the distance the signal travels. As a signal travels farther from its source, it encounters more obstacles and is subject to more absorption by the atmosphere, which can lead to a significant decrease in signal strength. Impedance, on the other hand, refers to the resistance to the flow of electric current in a circuit or transmission line. The impedance of a transmission line increases with distance due to the increased resistance caused by the line's properties, such as capacitance and inductance. This can lead to signal degradation, losses, and an increase in power consumption. As a result, impedance matching techniques are often used to ensure efficient transfer of signals in long-distance transmission.
