Earth is 149.6 billion meters from the sun and takes 365 days to make one complete revolution around the sun. mars is 227.9 billion meters from the sun and has an orbital period of 687 days. what is the ratio of earth's centripetal acceleration to mars's centripetal acceleration?
2.33
Centripetal acceleration is calculated with ac=v2r where v is the orbital speed and r is the radius of the orbit. First, find the orbital speed using the distance traveled in one period: v=2πrT where 2πr is the circumference of the orbit and T is the period. The centripetal acceleration can then be expressed as ac=4π2rT2. The ratio of Earth’s acceleration to Mars’s acceleration is ac,Eac,M=rE/T2ErM/T2M=149.6×109 m/(365 d)2227.9×109 m/(687 d)2=2.33.

C.

D.
to rural areas.
Rapid travel on interstate highways helped shift Texas's population to the suburbs.
Answer: Option B
Explanation:
The rapid travel on interstate highway helped Texas's population to move to suburbs. This also caused sub-urbanization of Texas. The people from urban places shifted to suburb areas because of easy means to move to the suburban areas.
The urban population shifted because of lack of places for houses or for employment purposes. Most people also do not find enough green places in the urban areas which is why they shift to suburbs.

The Aral Sea is now half the size it was in 1956.
The Aral Sea is now one-fourth its size as it was in 1956. Thus, the given statement is false.
What is Aral Sea?Between Kazakhstan in the north and Uzbekistan in the south, the Aral Sea was an endorheic lake that started to decrease in the 1960s and had largely dried up by the 2010s. About 1,100 islands had dotted its seas, giving the name, which roughly translates as "Sea of Islands," its meaning.
The Aral Sea, which was the fourth-largest lake in the world in 1960, has already decreased to half its original size as a result of unsustainable cotton farming, which started less than 40 years ago.
The year 2009 saw the disappearance of the southeast lake and the retreat of the southwest lake to a narrow strip near the western margin of the former southern sea. Over the years, sporadic water flows have caused the southeast lake to occasionally be replenished to a minor extent.
Therefore, the Aral Sea is now one fourth of its size and not half.

how does the north Atlantic current affect farming in the marine west coast climate of Europe?
The North Atlantic Current is a warm current. It brings in warm and moist air masses along the west coast of Europe. It also provides relative stability in the temperatures without extremes in the summer and the winter.
The conditions that this ocean current provides contribute to a fertile soil, enough precipitation, and nice climate, so the farming has nice predispositions to develop in this areas.
The plants that are very needy of water, deep and fertile soil, and do not require a lot of Sun light thrive in this areas, so no wonder that this areas are heavily used for agriculture.

After the landslide Communist victories in elections throughout Eastern Europe after WWII, why didn't the US try to stop the spread of Communist influence then?
Final answer:
After WWII, the US could not prevent the spread of communism in Eastern Europe due to a complex interplay of factors, including socioeconomic instability and popular support for communism in various nations. US containment policy involved the Marshall Plan and military alliances but was limited to nations like China with strong communist movements. The ultimate fall of communism was due to grassroots efforts rather than solely top-down interventions.
Explanation:
Following World War II, the United States was determined to promote stability, democracy, and open trade to counter the spread of communism. Despite fears of postwar economic weakness fueling the popularity of communism, the US initiated large-scale economic assistance through the Marshall Plan, investing $13.3 billion to rebuild Western Europe. The Soviet Union and Eastern European nations rejected these offers, steering towards communism with Soviet military support. The US strategy focused on containment through economic aid and military alliances, such as forming NATO in contrast to the Warsaw Pact. Nonetheless, domestic factors within countries like China, where communists gained popular support among the poor and landless due to promises of land and wealth redistribution, limited the effectiveness of US efforts.
The fall of communism is attributed to grassroots efforts by global citizens, challenging the perception of US presidents and Soviet Premiers as the solely critical agents of change. Efforts such as the Truman Doctrine and Eisenhower's interpretation of the 'Domino Theory' influenced US policies throughout the Cold War, including the provision of aid and military support to suppress communism in various regions.
Socioeconomic instability following World War II made Communist ideologies attractive in Europe and beyond, leading to the US stepping up economic aid to thwart this spread. However, the rise of independent movements in former colonies during the 1950s and 1960s often viewed the US with suspicion due to its support for its former European colonizers.
Later efforts to contain communism under the Kennedy administration included not only military aid but also substantial economic recovery investments in Western Europe, with a focus on democratic structure, exemplified by the recovery of West Germany into a prosperous democracy.

The longest river in the world in is the Amazon, located in South America, with a length of 6800 kilometers, compared to 6695 of the Nile River.
It is understandable that for a long time it was believed that it was the Nile. However, a few years ago the Brazilian Institute of Geography and Statistics published an investigation claiming that the Amazon is the longest river in the world.
On the other hand, the Sahara Desert itself is the largest (warm) desert in the world, but the Antartic Desert occupies the first place with an area of [tex]13,829,430km^{2}[/tex] compared to [tex]9,065,253 km^{2}[/tex] of the Sahara.

What is one way the tilt of the Earth's axis causes the seasons? A. The tilt of the axis brings the Earth closer to the sun in summer. B. The tilt causes the amount of time the sun shines each day to be greater on the part of the Earth where it is winter and less where it is summer. C. The tilt causes the Earth's rotation to slow down in the summer and speed up in the winter. D. The tilt causes the sun to shine more directly on the part of the Earth where it is summer and less directly where it is winter.
One effect of the Earth's axis' tilt on the seasons is The tilt of the Earth causes the sun to shine more directly in the summertime and less directly in the wintertime. As a result, choice (D) is accurate.
What is meant by Earth's axis ?The Earth's axis is currently tilted 23.4 degrees, or almost halfway between its extremes, and this angle is steadily getting smaller over the course of a 41,000-year cycle. It last reached its maximum tilt roughly 10,700 years ago, and it will do so again in about 9,800 years.
As obliquity decreases, it gradually contributes to the mildening of our seasons, resulting in increasingly warm winters and cooler summers that, over time, allow snow and ice to accumulate into enormous ice sheets at high latitudes.
As the amount of ice cover grows, more of the Sun's radiation is reflected back into space, which encourages even further cooling.
