Describe the contributions of Greek, Jewish, Muslim, and renaissance scholars to the scientific revolution



Try and give the simplest answer you can

Answers

The Greek contribution to the scientific revolution can be found in the work of ancient Greek mathematicians like Diofanto, Euclid, and Archimedes, who made the greatest advances in Western mathematics and engineering until the Renaissance. Another important Greek thinker was Aristotle since many scholars during the Middle Ages and the Renaissance relied on his work in order to take into account rationalist and empiricist investigations. The ancient Greek philosophy was revived thanks to Greek scholars during the late Middle Ages.

Jewish scholars also made great contributions to the development of modern science mainly in the field of medicine, but it was not confined only to it. Maimonides, for example, was a Jewish polymath from the 12th century whose several investigations in medicine, astronomy, and rationalistic philosophy were an important advance in the way of scientific thought.

Muslims scholars, as well, were great scientists. Relevant mathematicians and astronomers like Al-Jwarizmi, Al-Biruni and Omar Khayyam developed algebra in a brilliant way and prepared the terrain for the scientific revolution. Many of these scholars were Renaissance thinkers centuries before Renaissance, like Al-Hazen who made important discoveries in optics and developed the scientific method.

During the Renaissance, European scholars were leading the scientific revolution, like Copernicus, who stipulated the heliocentric model, Galileo Galilei, who demonstrated it empirically using the telescope, and Tycho Brahe and Johannes Kepler, whose works helped to understand the motion of the planets around the sun.

What factors helped shipping become so important to the economy of the middle colonies?

Answers

The Middle Colonies had lots of fertile soil, which allowed the area to become a major exporter of wheat and other grains. The lumber and shipbuilding industries enjoyed success in the Middle Colonies because of the abundant forests, and Pennsylvania saw moderate success in the textile and iron industry.

Final answer:

Shipping's importance in the middle colonies' economies can be traced back to their geographical location, abundant natural resources, and a diverse economy. Their location provided access to European markets and the natural resources facilitated industries like farming and shipbuilding. Meanwhile, the diverse economy characterized by agriculture and shipping-related industries necessitated a robust shipping economy.

Explanation:

The middle colonies, which included New York, New Jersey, Pennsylvania, and Delaware, greatly benefited from a variety of factors that shaped their economies. One of the key factors that made shipping important was their geographical location. Nestled on the Atlantic coast, these colonies had indirect access to European markets. Additionally, they had numerous ports and harbors that facilitated shipping.

Another crucial aspect was the abundant natural resources that these colonies possessed. The rich fertile lands were ideal for farming while the forests provided timber, which was a major commodity in shipbuilding.

Lastly, the growth of a diverse economy also played a significant role. Apart from agriculture, industries such as fishing, whaling, and shipbuilding flourished, all of which necessitated a strong and reliable shipping economy.

If you are standing on a headland, where is the water?

Answers

A headland is a coastal landform. It is a point of land, usually high, that extends into a body of water. If a headland is sufficiently large it is called a cape. They are often found in the same coastline as bays. However, a bay is flanked by land on three sides, while  a headland is flanked by water on three sides.

If you were to stand on a headland, you would find that you are facing the water, and the water is also to your left and right side.

Final answer:

If you're standing on a headland, you're surrounded by water on three sides. A headland is a coastal area that protrudes into the sea. The water you see could be a sea or a lake.

Explanation:

If you are standing on a headland, the water surrounds you on three sides as headlands are coastal areas that extend into the sea. Typically, headlands are high coastal landforms that provide panoramic views of the surrounding ocean or sea. They are formed as a result of differential erosion, when softer rocks erode quicker than harder rocks, leaving the harder rock protruding out.

For example, let's say you are standing on the uppermost point of a headland, you could see the water extending in front of you and to the left and right of you. Behind you would be the rest of the land. The water that you see could be a sea or a lake depending on the location of the headland.

why American dollar is most powerful currency in the world not others like indian rupees .
Thanks

Answers

Answer - The relative strength of the U.S. economy supports the. It's the reason the dollar is the most powerful currency. As of 2018, the U.S. had $1,671 billion in circulation. As much as half that value is estimated to be in circulation abroad.

The strength of the American dollar can be attributed to multiple factors which establish it as the most powerful currency in the world.

Firstly, the U.S. dollar is widely used and accepted in international transactions; it is the preferred currency for many central banks and is involved in over 90% of the $4 trillion worth of foreign exchange trades conducted daily. Secondly, this dominance originates from the post-World War II era where the United States took on a central role in shaping the international financial system. Lastly, the perceived trust and value of the U.S. dollar, along with its strong purchasing power, benefit consumers and tourists.

Exchange rate regimes and global trust in the U.S. economy play a significant role in the dollar's power. After the gold standard was abolished in 1971, currencies began to derive their value based on trust in the country's economy, and the dollar's perceived strength has remained high.

Whether a currency is strong or not can be advantageous or disadvantageous in different economic scenarios. For instance, importing firms may profit from a stronger dollar due to lower costs of imports, whereas export producers may suffer because their goods become more expensive in foreign markets. A strong U.S. dollar is particularly beneficial to U.S. tourists traveling abroad as they get more foreign currency per dollar, thus lowering the costs of their trips.

What methods did the Incas use to unify their large empire? PLEASE PLEASE ANSWER PLEASE I NEED HELP SO BAD

Answers

If you are talking about how the Incas organized their empire:  The Inca´s empire had a good administrative organization. The body of officials that, the, advised the Inca sovereign grouped and organized the population of the Empire. They regulated the works in communal welfare. All the regions used the official language: Runa Simi also later known as Quechua. They also verify their work and population using the census based on the decimal system.

On the other hand, if you mean who they expanded it: you should know there are several hypotheses on the phases of expansion of the Tahuantinsuyo. Some authors agree on the division of three phases. Each of the phases by different techniques according to the situation, organization and need at that time. The first expansion was the result of alliances that they used to expand their territories. The second and third was a result of conquers and internal  internal clashes.


Here is my answer please use your own words don't plagarize:

Some methods the Incas used to unify their large empire is that everyone had to speak the same language, making communicating easier. Another method was that conquered peoples could still worship their own gods as long as they honored the Sapa Inca. That made them less likely to rebel against not being able to worship their own god(s). The Incas also developed a lot of roads and bridges for traveling, so the government could more easily send messages to people who could be miles away! Of course they would pay someone to make the trip, they wouldn't go themselves!

what colony treated all religions equally.

A.New Jersey
B.New York
C.Pennsylvania
D.Maryland

Answers

All I can say is it deffinenty isn't maryland

"The correct answer is C. Pennsylvania colony treated all religions equally.

Pennsylvania, founded by William Penn, was known for its policy of religious freedom and tolerance. This colony was established with the intention of providing a safe haven for Quakers and others seeking religious freedom. The Frame of Government, Penn's original governing document, included provisions for liberty of conscience and was one of the first to guarantee freedom of worship for all residents, regardless of their religious beliefs.

To elaborate on the other options:

A. New Jersey: While New Jersey did have a degree of religious diversity and tolerance, it was not as explicitly established for the purpose of religious freedom as Pennsylvania was.

B. New York: New York was characterized by a diverse population and a degree of religious tolerance due to its Dutch origins and later British rule, but it did not have the same reputation for treating all religions equally as Pennsylvania did.

D. Maryland: Maryland was founded as a haven for Catholics, but it also experienced periods of religious intolerance, particularly against Catholics, despite the initial intent of its founder, Cecil Calvert, to create a space of religious freedom.

Therefore, Pennsylvania stands out as the colony that treated all religions most equally, making it the correct answer to the question."

how many 100 lb wolves can 1000000 lbs of vegetation support

Answers

TRICK QUESTION. wolves are carnivorous, meaning they eat only meat. their prey could live of vegetation so maybe that'd help them but if theres no prey and only vegetation they'd probably starve to death.

1,000,000 lbs of vegetation can support approximately 100 wolves, considering the energy transfer through trophic levels and the 10% rule of energy transfer.

Let's break this down with the following considerations:

Trophic Levels: In an ecosystem, energy is transferred through trophic levels. Typically, only about 10% of the energy from one trophic level is passed to the next. Vegetation represents the primary producers.Wolves' Diet: Wolves are carnivores primarily feeding on herbivores, hence secondary consumers. Herbivores are primary consumers that feed on vegetation.Energy Transfer: To support wolves, we must first support herbivores. If we assume 100,000 lbs of vegetation could sustain 10,000 lbs of herbivores (considering the 10% energy transfer rule), then 1,000,000 lbs of vegetation can support 100,000 lbs of herbivores.Supporting Wolves: Following the same 10% rule, 100,000 lbs of herbivores could theoretically support 10,000 lbs of wolves.Calculation: Since each wolf weighs 100 lbs, 10,000 lbs of wolves would equate to 100 wolves (10,000 ÷ 100).

Therefore, 1,000,000 lbs of vegetation can support approximately 100 wolves.

13. The upper radiator hose collapses when the engine gets cool. A defective _______ is the most likely cause. A. hose B. pressure cap C. thermostat D. hose spring

Answers

The upper radiator hose collapses when the engine gets cool. A defective "cap" is the most likely cause.


The most widely recognized reason for radiator hose collapse is a vacuum issue caused by a defective radiator cap. Caps are evaluated around 14– 16 psi. Under ordinary conditions, tops should discharge the negative weight caused when a motor chills off and the fluid coolant contracts. They do lose their rating following quite a while of utilization or in some cases they basically turn out to be excessively messy, making it impossible to work. In these cases, everything necessary to settle the issue is another cap. Simply ensure you supplant the old one with new cap of a similar pressure rating.

Answer:  The correct answer is : B. pressure cap

Explanation:  When the radiator hose collapses, it is due to a vacuum problem caused by a defective radiator cap. Changing the hose is not difficult but requires great care when handling the coolant. The hoses are very important for the cooling system, there are two hoses one upper and one lower very thick and resistant since they must withstand high pressures and too much heat.

Bailey decided to confront her fear of dogs by volunteering to look after Arnold, the neighbor's golden retriever. By the end of the day, she was becoming quite comfortable around Arnold. However, when the smoke detector accidentally went off, she found that some of her fear had returned.

Answers

What is the question?

Bailey's experience with overcoming her fear of dogs through spending time with Arnold and the subsequent return of fear due to a smoke detector involves concepts of associative learning, classical conditioning, stimulus generalization, extinction, and spontaneous recovery.

The student's question involves Bailey's experience of confronting her fear of dogs by spending time with Arnold, a golden retriever, and how her fear partially returned when a smoke detector went off. This scenario can be analyzed from a psychological perspective, particularly through the lens of associative learning and classical conditioning. Associative learning is a learning process in which a new response becomes associated with a particular stimulus. In Bailey's case, her initial fear of dogs may have been reduced through positive interactions with Arnold, demonstrating a form of associative learning where her fear response was being conditioned to decrease in the presence of dogs. However, the sudden noise of the smoke detector might have caused a form of stimulus generalization, where her anxiety and fear response were triggered not just by dogs, but by loud, sudden noises associated with her time around Arnold.

Explanation:

It is difficult to judge the actions and perspectives of people in the past. As Lula Flannigan describes, Union soldiers sometimes looted households in the Confederacy. Part of the reason for doing this was to break the Confederacy's will to fight. Another probable reason was that the soldiers wanted revenge for having to fight a war. In earlier history, it was very common for an invading army to steal or destroy the goods that were in households.                         ~Props to the other person who got the answer first!~
