What was thomas edison's first invention?

Answers

Answer 1
his first invention was a phonograph 
Answer 2

Final answer:

Thomas Edison's first invention was an automatic vote counter, which he failed to sell due to lack of government interest. He is more famously known for inventing the practical incandescent light bulb and for pioneering organized research laboratory practices.

Explanation:

Thomas Edison, whose full name is Thomas Alva Edison, is a world-renowned inventor with a remarkable record of 1,093 patents to his name. Although he is often credited with the invention of the practical incandescent light bulb in 1879, his first invention was, in fact, an automatic vote counter. This early invention, designed to tally votes more efficiently, unfortunately did not attract interest from the government because quicker vote tallying was not a priority at the time. Thus, despite its potential civic benefits, Edison's vote counter never saw commercial success.

Edison's work extended well beyond the lightbulb; he was a true innovator who also developed other key inventions like the phonograph and motion picture projector. Edison's fame and contributions to technology stemmed from both his inventive genius and his establishment of a large, organized research laboratory, which was pivotal in accelerating the development of new technologies.

The first major public demonstration of Edison's lighting system was in New York City, in 1881. This development was a crucial step in the widespread adoption of electric lighting, previously dominated by gas lighting and carbon arc electric lamps, which were not suitable for indoor use. His ingenuity not only revolutionized lighting but also laid the groundwork for the modern electrical system, including essential components like fuses, meters, and switches.

How and why did Theodore Roosevelt change US policy toward Latin America?

Answers

Theodore Roosevelt changed US policy toward Latin America with the Roosevelt Corollary to the Monroe Doctrine, endorsing intervention to protect US interests and prevent European influence in the region.

Theodore Roosevelt significantly changed US policy toward Latin America by implementing the Roosevelt Corollary to the Monroe Doctrine. This policy was predicated on the belief that the United States had the authority to intervene in Latin American affairs to protect its economic and political interests. The 'big stick' philosophy endorsed the use of military intervention as a means to enforce this policy, especially to prevent European powers from collecting debts in a way that could undermine US predominance in the Western Hemisphere. Roosevelt's actions were motivated by the necessity to prevent European intervention, protect American investments, and maintain stability close to US shores. His approach to Latin American policy was later contrasted by Franklin D. Roosevelt's Good Neighbor Policy, which aimed to reduce intervention and improve relations with Latin American countries.

Analyze the causes of the Spanish-American War by describing the influences of Yellow Journalism, the incident involving the U.S.S. Maine, and the belief in Imperialism

Answers

The Spanish-American War was a conflict between the Kingdom of Spain and the United States of America that took place from April to August 1898. It was caused by American demands that Spain resolve peacefully the insurrection in Cuba, which Spain was unable to do. The explosion of the American battleship "Maine" raised tensions but was not the main cause of the war, nor was "yellow journalism" in New York City that harped on Spanish atrocities. The war ended after quick, decisive naval and 
military victories for the United States in the Philippines and Cuba. Only 113 days after the outbreak of war, the Treaty of Paris, which ended the conflict, gave the United States ownership of the former Spanish colonies of Puerto Rico, the Philippines and Guam. The U.S. took control of Cuba, ended the insurrection, expelled the Spanish and granted independence there in 1902.

How did early renaissance artists learn to create more realistic art than their predecessors

Answers

Final answer:

Early Renaissance artists learned to create more realistic art through the use of perspective, realistic proportions, foreshortening, sfumato, and chiaroscuro. They also studied anatomy to accurately depict the human body.

Explanation:

During the Early Renaissance, artists began to reject the Byzantine style of religious painting and strove to create realism in their depiction of the human form and space. This aim toward realism began with Cimabue and Giotto, and reached its peak in the art of the "Perfect" artists, such as Andrea Mantegna and Paolo Uccello, who created works that employed one point perspective and played with perspective for their educated, art knowledgeable viewer.

In addition to perspective, Renaissance artists also developed other techniques to create more realistic art. They used realistic proportions, foreshortening (exaggerating the part of an object closer to the viewer), sfumato (gradual blending of tones to create a sense of depth), and chiaroscuro (contrasting light and dark to create a sense of volume and dimension).

Furthermore, Renaissance artists were influenced by the rediscovery of classical texts and ideas during the period. They studied anatomy through dissections and incorporated their knowledge of human anatomy into their artwork, resulting in more accurate depictions of the human body.

Why did support from people in the Chinese countryside help the Communists more than support from people in the cities helped the Nationalists?

Answers

In the cities, people had mixed feelings about which side to support, so they did not present a united front.

The options of the question are, A) many more people lived in the countryside, so they made Communist the stronger side. B) People in the cities were confident that the Nationalist would win, so they remained passive. C) In the cities, people had mixed feelings about which side to support, so they did not present a united front. D) In the countryside, people were accustomed to nearly constant warfare and so were well prepared.

The correct answer is C) In the cities, people had mixed feelings about which side to support, so they did not present a united front.

The support in the Chinese countryside helped the Communist more than support from people in the cities helped the Nationalist because in the cities, people had mixed feelings about which side to support, so they did not present a united front.

The Nationalist Party was more popular in the cities of China because the wealthy people that supported the Nationalist lived there. But other people had mixed feelings. Some Chineses supported the Communist Party although they lived in the cities. So, people in the cities did not present a united front to favor the Nationalist. The people from the countryside of China were the ones who helped the Communist.  


Select the TWO political parties that were formed in the United States while Washington was president.

Anti-Federalist
Federalist
Tories
Democratic-Republican
Whigs

Answers

The Federalists, and the Democratic-Republicans.

Answer:

The two political parties that were formed in the United States while Washington was president were the Federalist Party and the Democratic-Republican Party.

Explanation:

The American bipartisanship was born in the first years of independent life of the nation under the influence of the events associated with the French Revolution, during the presidency of George Washington. The international crisis provoked by the events in Europe caught the United States between the two main fighting nations: France and Great Britain. The young and still vulnerable American republic was threatened by a conflict that was not its responsibility and could not control.

In this context, the struggle between two political groups led to the development of the first American political parties: the Federalist Party and the Republican Party. The federalists were led by Alexander Hamilton and identified with the interests of the country's most urban and commercial region, the Northeast. These proposed the development of the United States as a manufacturing and commercial country, for which they defended the creation of a national bank, the payment of the national debt and the collection of tariffs on imported products. At the international level, the federalists viewed the events of the French Revolution with suspicion and did not hide their sympathies for Great Britain. The Democratic-Republicans were led by Thomas Jefferson and represented the interests of the slave and agrarian south. These favored the development of a smallholder agricultural economy and opposed tariffs and the creation of a national bank because they believed they would affect the interests of ordinary citizens. Internationally, Jefferson and his followers sympathized with revolutionary France and displayed a clearly anti-British attitude.

What problems arose during the settlement of the frontier among farmers?

Answers

The very first settlement delt with a plague that took out the first settlement.

Answer:

The answer to this question is quite extensive, and it begins with understanding that as settlers began to farm the newly colonized lands beyond the East Coast, towards the West, there were several issues that torubled them.

First, there was lots of land to take from, but at a great expense, since farmers who settled far from the already civilized East Coast, were basically at the mercy of nature, Native Americans, and the resources they could procure for themselves.

Second, during the 1800´s, as the railroad systems began to expand, and new horizons to open up, small farmers also came to crash against the realities of industrialization and the growth of big businesses that were able to surpass them in production. This led to trouble as these smaller farmers were forced to seek ways to balance out the equation. As such, not only were they forced to adapt to whatever the railroad companies wanted to charge them to transport their products, but in order to compete, they had to start taking out loans from banks, which later they were not able to repay because sales for small farmers did not go as well, with the bigger businesses hugging the available markets.

Finally, the biggest problem that arose for these farmers was the issue that past the frontier, and near it, they were completely at the mercy of Native tribes, especially hostile ones, who would ravage farmers´ lands in order to push them out of their territories.

Another problem that must be noted is that with the expansion of the frontier, the fever for gold and silver also took people over, so that farmers had to face land issues not just with Native tribes, but also with settlers whose interests were different from agriculture.

These are only a few of the problems that were faced by settlers, especially farmers, as they settled the Western frontier.

what aspects of Confucianism and Daoism do you think contributed to their long lasting influence?

Answers

Confucianism and Daoism are considered philosophical world views and ways of life. Each has its own set of characteristics that make of them a long-lasting influence to adopt for a lifetime.

Daoism is focused on understanding nature and embracing it as it is - regarding the nature of humans and that of the environment that surrounds them. This broad approach of understanding life allowed Daoism to become a religion with and organized doctrine and cult practices.

In the case of Confucianism, its focus on improving human behavior with the means of achieving harmony served not only as an ideology to adopt as a personal way of life, but as a ruling (discipline) model for an entire society.

Confucianism and Daoism contributed to their long-lasting influence because for the Chinese the two spiritual teachings a counterweight of life. One teaches harmony with humans while the other teaches the search for identity through natural things.

 

EXPLANATION  

Taoism and Confucianism have lived together in China for more than 2,000 years. Confucianism deals with social problems, while Taoism deals with the search for meaning. They share the same beliefs about humans, society and the universe, even though this idea existed long before philosophy. Both began as philosophies, each later taking on a religious nuance.  

Legend has it that Lao-tzu and Confucius discussed the Imperial Archives. Lao-tzu was not impressed by the stunning robe worn by Confucius and did not agree to look back into the past. "Get rid of your polite air and the futile appearance of your fine robe.  

The wise man does not show his wealth to people he does not know. And he cannot learn justice from the ancients. Despite the disagreement between Lao-tzu and Confucius, both Confucianism and Taoism have become a guide for Chinese society. They have ruled China through the valleys and peaks of its long history.
