Discuss the position of the Federalists and anti-federalists related to ratification of the Constitution. Use facts. WILL MARK BRANLIEST

Answers

Answer: The Federalists wanted a strong government and strong executive branch, while the anti-Federalists wanted a weaker central government. The Federalists did not. Hope This Helps You! Happy Early Christmas! :D Explanation: In 1787, a convention was called in Philadelphia with the declared purpose of revising the Articles of Confederation. However, many delegates intended to use this convention to draft a new constitution. All states except for Rhode Island sent delegates, though not all delegates attended the Convention. At the Convention, the primary issue was representation of the states. Under the Articles, each state had one vote in Congress. The more populous states wanted representation to be based on population (proportional representation). James Madison of Virginia crafted the Virginia Plan, which guaranteed proportional representation and granted wide powers to the Congress. The smaller states, on the other hand, supported equal representation through William Paterson’s New Jersey Plan. The New Jersey Plan also increased the Congress’ power, but it did not go nearly as far as the Virginia Plan. The conflict threatened to end the Convention, but Roger Sherman of Connecticut proposed the “Great Compromise” (or Connecticut Compromise) under which one house of Congress would be based on proportional representation, and the other house would be based on equal representation. Eventually, the Compromise was accepted, and the Convention was saved.

Articles of Confederation: The Articles of Confederation, formally the Articles of Confederation and Perpetual Union, was an agreement among the thirteen founding states that established the United States of America as a confederation of sovereign states and served as its first constitution.

delegate: A person authorized to act as representative for another; in politics, a party representative allocated to nominate a party candidate.

Three-Fifths Compromise: an agreement between Southern and Northern states reached during the Philadelphia Convention of 1787, in which three-fifths of the population of freed slaves would be counted for representation purposes regarding both the distribution of taxes and the apportionment of the members of the United States House of Representatives.A Constitutional Convention was called in the summer of 1787 to change the Articles of Confederation. During this time, many compromises were formed to appease regional factions.

The Great Compromise brought together the New Jersey Plan and the Virginia Plan to create the Constitution ‘s legislative system. The Three-Fifths Compromise appeased Southern representatives by allowing them to count slaves for representation and taxation purposes.

The Federalists wanted a strong government and strong executive branch, while the anti-Federalists wanted a weaker central government.

The Federalists did not want a bill of rights —they thought the new constitution was sufficient. The anti-federalists demanded a bill of rights. Hope This Helps You! Happy Early Christmas! :D

SUBMIT

Answers

Answer:

C.  He made electricity available to business owners, so businesses

could run at all hours.

Explanation:

The practices of using engines as substitutes for animal and human muscle power and of using machines to produce goods took on a different character after about 1850. Sometimes called the second Industrial Revolution (or the second phase of the Industrial Revolution), this new phase differed from the original in several ways, and marked an important shift in the progress of the revolution.

With the rapid spread of the Industrial Revolution from Great Britain to the United States and Europe came a wave of inventions, some of which were new, many of which simply improved upon existing machines. Advances in science, particularly in chemistry, led to widespread changes, especially in agriculture and medicine. Petroleum became an important source of energy, leading to a new class of mobile machines (notably automobiles and trucks). Electricity was developed into a new means of delivering energy, leading to the introduction of small motors as well as superior lighting for both factories and houses. A new process of stringing together several inventions to create complex systems revolutionized manufacturing, transportation, and communications, and helped to create new business enterprises that were much larger than anything that had come before.

Taken together, these changes accelerated the impact of the Industrial Revolution on society throughout Europe and North America. Whereas everyday life for most people had changed relatively little from 1700 to 1800, it changed profoundly from 1800 to 1900 and beyond.

Why did Antoine Lavoisier reject the phlogiston theory? What is the modern-day theory that it

contradicted?

Answers

Answer:

Lavoisier did not expect his ideas to be adopted at once, because those who believed in phlogiston would "adopt new ideas only with difficulty."

Antoine Lavoisier disproved the existence of phlogiston and helped to form the basis of modern chemistry using Joseph Priestley's discovery of oxygen.

Explanation:

Lavoisier put his faith in the younger generation who would be more open to new concepts. Two years later, in 1791, the results were obvious.

Antoine Lavoisier determined that oxygen was a key substance in combustion, and he gave the element its name. He developed the modern system of naming chemical substances and has been called the “father of modern chemistry” for his emphasis on careful experimentation.

Describe the backgrounds and philosophies of Patriots and Loyalists. Why did colonists with such diverse individual interests unite in support of their respective causes

Answers

Answer:

The correct answer to this open question is the following.

In colonial American times, previous years of the beginning of the Revolutionary War of Independence, Americans were basically divided into two groups: Patriots and Loyalists. Colonists with such diverse individual interests united in support of their respective causes because problems were so many and the division started to polarize even more.

Patriots supported the idea of Independence from England, meanwhile, Loyalists thought that the colonies wouldn't be the same without the support of the English crown.

Patriots wanted to achieve liberty and independence by winning the war. Loyalists tried to maintain things as they were because they always supported the King of England.
