What’s the force of a pitching machine on a baseball?
Baseballs pitched by a machine have a horizontal velocity of 30 meters/second. The machine accelerates the baseball from 0 meters/second to 30 meters/second in 0.5 seconds. If a baseball has a mass of 0.15 kilograms, the force the machine exerts is blank newtons. Use F = ma, where .

Answers

Answer 1

Answer:

The Machine exerts a force of 9N.

Explanation:

Inital velocity (u) = 0 m/s

Final velocity (v) = 30 m/s

Time (t) = 0.5 s

Acceleration (a) = (v-u)/t

= (30-0)/0.5 m/s2

= 60 m/s2

Mass = 0.15 kg

Force = Mass*Acceleration

= 0.15*60 N

= 9 N

Which act placed a tax on goods before they could be bought or sold in the colonies?
O A) Declaratory Act
O B) Stamp Act
O C) Sugar Act
O D) Townshend Acts

Answers

Answer:

D, The Townshend Acts

Explanation:

The Townshend Acts were imposed by the British Parliament on imported goods to the colonies. These taxes lowered colonist profits and since it was done without colonial representation in parliament, these acts were a big part of the grievances of the colonists of the British abusing their power over the colonies.

I’m pretty sure it is D) the Townshend Acts. this is because the stamp act was placed on stamps, and the sugar act was placed on taxing sugar.

Which statement about American views of the French Revolution is FALSE? * A) At first most Americans welcomed the French Revolution as a peaceful blow against tyranny. B) After the Reign of Terror began, Jeffersonians believed that some bloodshed was a small price to pay for liberty. C) After Britain and revolutionary France went to war, Washington proclaimed America´s official neutrality despite the Franco-American alliance of 1778. D) Pro-French Jeffersonians and Federalists both accepted the need for Washington´s neutrality policy, which calmed partisan tensions for a time.

Answers

The correct answer is D) Pro-French Jeffersonians and Federalists both accepted the need for Washington´s neutrality policy, which calmed partisan tensions for a time.

The statement about American views of the French Revolution that is FALSE is "Pro-French Jeffersonians and Federalists both accepted the need for Washington´s neutrality policy, which calmed partisan tensions for a time."

It is correct to say that at the beginning of the French Revolution, Antifederalists led by Thomas Jefferson supported the revolution. They considered that the French people had the right to fight for justice, equity, public participation, and prosperity. However, on the other hand, Federalists led by Alexander Hamilton opposed the revolutionary movement.

The federal government was not in a position to have an official position, that is why President George Washington decided to maintain a foreign policy of neutrality. He did not want the US to be involved in another conflict after the consequences of the Revolutionary War of Independence.

How did sectionalism arise from the Denmark Vesey Plot, and the abolitionist
movement?

Answers

The correct answer to this open question is the following.

Sectionalism arose from the Denmark Vesey Plot and the abolitionist

movement because the Denmark Vesey plot made things worse with the racial and slavery issue in the South. The Denmark Vesey Plot contributed to the increase of sectionalism in that the General Assembly responded with measures making it harder to free slaves, angering abolitionists.

Denmark Vesey had been plotting a black people insurrection in July 1822, using his position at the local Methodist church. It is said that he had been organizing 1000 black people to take the city of Charlestown, in South Carolina, when one slave showed his loyalty to his owner and revealed the plot. White authorities acted promptly and they prevented the riot, arrested Vesey and other leaders, and the sentence was they were executed.

Choose the right phrase to complete the sentence. According to Bush, the purpose of the war on terror is to defeat only al-Qaeda. all global terrorist groups. only terrorist groups in the United States.

Answers

Answer:

The answer is "all global terrorist groups"

Explanation:

The war on terror, otherwise called the Global war on terrorism, is a global military mission dispatched by the US government after the September 11 assaults. The objectives of the mission are basically Sunni Islamic fundamentalist outfitted gatherings situated all through the Muslim world, with the most noticeable gatherings being Al-Qaeda, the Islamic Express, the Taliban, Tehrik-I-Taliban Pakistan, and the different establishment gatherings of the previous two associations.

The naming of the mission uses an allegory of battle to allude to an assortment of activities that don't comprise a particular battle as customarily characterized. U.S. president George W. Bramble originally utilized the expression "war on terror" on 16 September 2001, and afterward "battle on dread" a couple of days after the fact in a proper discourse to Congress.

In the last discourse, George Hedge expressed, "Our adversary is an extreme organization of fear based oppressors and each administration that upholds them." The term was initially used with a specific spotlight on nations related with al-Qaeda.
