How many years did it take for thomas edison to invent the light bulb?

Answers

Answer 1
Thomas Edison's teachers said he was "too stupid to learn anything." He was fired from his first two jobs for being "non-productive." As an inventor, Edison made 1,000 unsuccessful attempts at inventing the light bulb.
Answer 2
Final answer:

Thomas Edison patented the incandescent light bulb in 1879 after developing it with his team at Menlo Park. The invention was a culmination of extensive research and thousands of filament tests, leading to the widespread use of electric lighting.

Explanation:

Thomas Edison's name is synonymous with the invention of the light bulb, which is regarded as one of the most significant inventions in history. This process did not happen overnight; it was the result of years of persistent experimentation and innovation. Edison patented the incandescent light bulb in 1879, after years of work that included testing over six thousand different filament materials. He was not working in isolation, as he had a large team of scientists, engineers, and craftsmen in his research laboratory.

It is important to note that while Edison made substantial improvements to the light bulb, he did not create the concept from scratch. Instead, he refined the designs of earlier inventors to produce a more practical and long-lasting version of the light bulb. Through his laboratory at Menlo Park and with ample financial backing, Edison's collective innovations contributed immensely to the wide adoption of electric lighting.

The bill of rights is an important addition to the constitution because it?

Answers

Hi Ariana, thanks for asking a question here on Brainly.

The Bill of Rights is an important addition to the constitution because it guarantees a person's basic rights. 

Answer: Letter A ✅

Hope that helps! ★ If you have further questions about this question or need more help, feel free to comment below or post another question and send the link to me. -UnicornFudge aka Nadia 

Final answer:

The Bill of Rights was added to the Constitution primarily because certain key states refused to ratify it without these specific protections for individual liberties. These first ten amendments limit the power of the government and protect rights such as free speech, religion, and fair legal proceedings. The Fourteenth Amendment and judicial interpretation have expanded these rights to apply at the state level as well.

Explanation:

The Bill of Rights is an essential addition to the Constitution because it serves as a safeguard for the individual liberties and freedoms that define American democracy. It was added primarily because key states would not ratify the Constitution without the inclusion of these protections. This set of amendments limits the power of the government and provides a range of rights, including freedom of speech, religion, press, assembly, the right to bear arms, and protections during legal proceedings. The Bill of Rights was introduced by James Madison in 1789 and formally adopted in 1791 after the Constitution was ratified.

Over time, these first ten amendments have become a core part of American values, symbolizing what Americans cherish in their political and social systems. Additionally, the Fourteenth Amendment and various Supreme Court decisions have extended these protections at the state level through a process known as selective incorporation. The balance of individual rights against society's interests continues to be a significant topic of debate in American jurisprudence.

What is monotheism and why is did this belief set the ancient jews apart?

Answers

Monotheism is belief in just one god, while polytheism is belief in more than one god. Prior to the Deuteronomistic reforms of King Josiah of Judah, in the seventh century BCE, the Hebrew people were polytheistic with a religion almost indistinguishable from those of their neighbours. King Josiah made monotheism the official religion of Judah, although many scholars believe that polytheistic beliefs remained very widespread until the Babylonian Exile. At this stage, the only other monotheistic religion in the Near East was Zoroastrianism, the religion of the benefactors of the Jews. For the remainder of the first millennium BCE, Jewish monotheistic beliefs were almost unique in the world and were written back into the Bible to provide a largely monotheistic history of the Israelites.

During the ice ages, why were hunter-gather societies in much of europe unlikely to use large wood timbers for their dwellings?

Answers

Hunter gatherers were not likely to use large wood timbers for their dwellings simply because large trees would not grow in this environment during the Ice Ages. Trees can survive in temperatures as low as 6 degrees Celsius and so would not flourish during the ices ages. Grasslands would more likely flourish (in summer months) in this type of environmental conditions. 
Final answer:

Hunter-gatherer societies in Europe during the Ice Ages were unlikely to utilize large wood timbers for dwellings due to resource scarcity, their nomadic lifestyle, and the impracticality of transporting heavy materials as they followed food sources.

Explanation:

During the Ice Ages, hunter-gatherer societies in Europe were unlikely to use large wood timbers for their dwellings primarily due to the scarcity of resources and the nomadic nature of their subsistence lifestyle. Hostile climates and the covering of much of the land by ice made the resource of wood much less available. Moreover, because these societies were constantly on the move following food sources such as herds of animals and gathering edible plants, constructing permanent structures with heavy and large materials would have been impractical. Instead, they built more temporary and mobile forms of shelters that could be easily abandoned, like huts and tents made of mammoth bones or lightweight materials that could be moved as they migrated.

How did the scalawags change government in the south?

Answers

Scalawags Changed the government in the South by bringing the republican ideas to the politics of South.  

Further Explanation:-

White Southerners were referred as Scalawags by their enemies. They were the group of delegates who were related to the southern reconstruction era of legislatures. The majority of Scalawags belonged to non- Slaveholding small farmers who remained loyal to the Union during the Civil war. The party which they were more inclined to and supported was “Republican Party’. In each state the Republican Party was divided by Scalawags who were more conservative and Carpetbaggers who were considered as ‘Radical’ with the support of their black allies on the other side.  On the account of Humanity, Scalawags were seen on the lower side as compared to carpetbaggers. Carpetbaggers won in most of the cases and that led to Scalawags moving towards more democratic and conservative opposition. During the Reconstruction era which took place after civil war, Scalawags formed their coalitions with northern newcomers and black freedmen because they wanted to take control of the state and local governments. Scalawags were a group of minorities but they gained power through taking advantage of the laws which were there during reconstruction in 1867.

What was the purpose of the deuteronomistic history?

Answers

The Deuteronomist, or simply D, is one of the sources identified through source criticism as underlying much of the Hebrew Bible (Christian Old Testament). Seen by most scholars more as a school or movement than a single author,[1] Deuteronomistic material is found in the book of Deuteronomy, in the books of Joshua, Judges, Samuel, and Kings (the Deuteronomistic history, or DtrH), and also in the book of Jeremiah. (The adjectives Deuteronomic and Deuteronomistic are sometimes used interchangeably: if they are distinguished, then the first refers to Deuteronomy and the second to the history.)[2]

It is generally agreed that the Deuteronomistic history originated independently of the books of Genesis, Exodus, Leviticus and Numbers (the first four books of the Torah, sometimes called the "Tetrateuch", whose sources are the Priestly source, the Jahwist and the Elohist), and the history of the books of Chronicles; most scholars trace all or most of it to the Babylonian exile (6th century BCE), and associate it with editorial reworking of both the Tetrateuch and Jeremiah.[3] hope it helps sorry if it did not


Final answer:

The Deuteronomistic History aimed to explain how God's protection and guidance were manifest in the lives of the Israelites, illustrating the importance of adherence to their Covenant with Yahweh and affirming Jewish laws and identity through the historical narrative.

Explanation:

The purpose of the Deuteronomistic History was to provide a theological explanation for the events in the life of the Israelites, illustrating how God protects His chosen people and guides their destiny. This collection of texts within the Hebrew Bible, including the history of Joseph, King David, and the wanderings of Israel, demonstrates the belief that the entire history of mankind is part of a divine plan of salvation, centered upon the truths entrusted to Israel. The Deuteronomistic History seeks to affirm the importance of following the Covenant with Yahweh, illustrating that the defeats and successes of the Hebrew people were directly related to their fidelity or lack thereof to their exclusive worship and covenant with Yahweh. It also aimed to reaffirm the laws and doctrines that shaped Jewish identity and belief, showing that these laws were superior and ensuring the survival and identity of the Jewish people through history. By comparing sacred history with profane, it endeavored to demonstrate the general assent of mankind to the events recorded, such as the renewal of the world after the flood, which was commemorated in various rites and myths across cultures.

How did the geography of China affect the development of early civilization there? Be sure to describe China’s geography and explain how it affected the development of civilization there.

This is a long one!
The early Chinese civilization was located between two main rivers, the Yangtze river and the Hung He river, because unlike most of china, the plain between the two rivers is fertile, allowing the people to grow rice and other crops.. In addition, China was surrounded to the west by mountains and deserts.
Enjoy the rest of your day!
As noted by the other Brainly user's response here, early Chinese civilization developed between the Yangtze River and the Huang He River (or Yellow River), because the plain between the rivers is fertile, allowing for the development of agriculture.  It's also worth noting that the these two rivers extend for hundreds of miles from west to east before reaching the sea.  This facilitated trade and transportation on the rivers.  It also allowed Chinese rulers to maintain control and communication across the wide expanse of main Chinese territory.

Also worth noting would be the mountains and deserts and ocean that set China off from other lands.  Large mountain ranges exist in the south and west regions of China -- such as the Himalayan Mountains, Kunlun Mountains, and Tianshan Mountains.  The Gobi Desert sits in the northern part of China, and the Pacific Ocean is to the east.  These various geographic features set China off from other lands, so that civilization there  developed in its own unique ways, apart from outside influence.

To determine whether discriminatory laws are constitutional, the Supreme Court subjects them to the _____.

A.comparative test
B.reverse discrimination test
C.rational basis test
D.constitutional analysis test

Answers

 it is D constitutional analysis test

"The correct answer is C. rational basis test.

When the Supreme Court reviews a discriminatory law to determine its constitutionality, it typically applies the rational basis test. This test is the most deferential standard of review used by the Court. According to this test, the law will be upheld if it is rationally related to a legitimate government interest. The government does not need to prove that the law is the best way to achieve its interest, only that it is a rational way.

The other options are not standard tests used by the Supreme Court in the same way:

A. Comparative test - This is not a standard term for a legal test used by the Supreme Court.

B. Reverse discrimination test - While the Supreme Court has addressed issues of reverse discrimination, it is not a distinct legal test but rather a consideration within the broader context of equal protection analysis.

D. Constitutional analysis test - This is a broad term that could encompass many different types of legal analysis, including the rational basis test, and is not a specific test in itself.

Therefore, the rational basis test is the correct answer for the standard of review applied to most laws that do not involve suspect classifications or fundamental rights, which would trigger a higher level of scrutiny, such as strict scrutiny or intermediate scrutiny."

According to article viii of the articles of confederation, who is responsible for supplying funds for the war effort against great britain?

Answers

Article VIII says that in forming an army to protect the United States, all state legislatures have the authority to appoint colonels and army officers; while from the Common Treasury, it will be from where they will obtain the money necessary to pay the expenses of a war, or to fight an enemy or danger, that threatens the country: this only if the Congress allows it. However, it is the responsibility of all states to contribute to the common treasury, according to the value of each state, based on the totality of their lands. Congress, making use of topography, will deduct the total amount to be paid per state. The taxes to support the common treasury will be collected by the state legislatures, and thus ensure the necessary money for an army.
