during a science lab, Carina measured the mass of an object to be 23.4 grams. the actual mass turned out to be 22.5 grams. What was the percent error in Carina's measurement?

Answers

Answer 1

Answer:

formula for percent error (P): the absolute value of the actual observed value (A) minus the expected value (E) all divided by the expected value (E) multiplied by 100

[tex]P = |\frac{A-E}{E}|[/tex] x 100

plugging in those values would give us 3.85% when rounded to two decimal places

Given what you know about the geography and chronology of the Chavin and Nazca, what might explain the fact that the Chavin and Nazca both used underground aqueducts to transport water?

The Nazca and the Chavin both used water for certain religious rituals.
The Nazca and the Chavin both adopted technology from the Maya.
The technology of the Chavin likely influenced the later Nazca.
The technology of the Nazca likely influenced the later Chavin.

Answers

What might explain the fact that the Chavin and Nazca use underground aqueducts to transport water is that Chavin's technology likely influenced the later Nazca.

The ancient Chavin civilization was a pre-Inca civilization that arose in Peru in the year 1500 BC to 300 BC. Its economy was based on gathering, hunting, fishing and agriculture.

The Chavin people's underground aqueducts were developed as a hydraulic technique to improve agricultural practice.

The Nazca were an ancient civilization that developed in Peru around 100 BC. As a highlight, we can mention the mathematical and architectural knowledge of this people, who built great religious temples.

The Nazca economy was also based on agriculture, and they developed the system of underground aqueducts to transport water as a direct influence of the Chavin culture, which was the civilization prior to the Nazca civilization.

Therefore, the correct alternative is:

The technology of the Chavin likely influenced the later Nazca.

Explain the final debate between Lincoln and Douglas. Where did it take place, what points did each try to make, and how many people attended?

Answers

Douglas and Republican challenger Abraham Lincoln during the 1858 Illinois senatorial campaign, largely concerning the issue of slavery extension into the territories. The slavery extension question had seemingly been settled by the Missouri Compromise nearly 40 years earlier.
The final debate between Lincoln and Douglas was on October 15, 1558 in Alton, Illinois. Lincoln argued against the spread of slavery. While Douglas maintained each territory should have the right to decide whether it would become free or allow slavery. There were close to 20,000 people who attended. Lincoln argued that there should be no reason why black men could not have the same rights as a white man per the Declaration of Independence. Douglas always felt the white man was superior and that no black man were to ever be considered a citizen but to always be subordinate to the white man.

Why was it easy for Jane to move around while she was exploring

Answers

Answer:

Jane Eyre takes place in five settings: Gateshead Hall, Lowood School, Thornfield Hall, Moor House, and Ferndean. Each setting encompasses a different stage in Jane’s life. Gateshead, where the Reeds live and Jane spends her young childhood days, contains the terrifying red-room, the place in which she undergoes her first truly terrifying experience: a supposed encounter with her Uncle Reed’s ghost. Jane’s marked change from this encounter prompts Mrs. Reed to send her to Lowood School, a place filled with similarly oppressive circumstances. Brontë modeled the harsh conditions of Lowood School after an English school she attended with her sisters. Just like in the novel, students suffered from typhus and consumption. Scholars note that Mr. Brocklehurst’s doctrine of privation matches Evangelical doctrines popular in Victorian England, and many read this section as a critique of those branches of Protestantism. After Lowood, Jane moves on to Rochester’s Thornfield Hall, which has a frightening, ominous presence at night, and Brontë uses quite a few other Gothic elements, such as descriptions of the supernatural, to define the setting. Many Gothic novels explore anxieties around sexuality, and accordingly Thornfield is where Jane explores romantic passion with Rochester. Moor House and Ferndean have less developed physical significance, but important names. The word “moor” signifies a mooring, a place where something is docked. Moor House is where Jane receives her inheritance, granting her stability for once in her life. The “fern” in Ferndean symbolizes the new growth Jane and Rochester will experience there, and Jane confirms that she has spent the past ten blissful years there by Rochester’s side, as his wife and his equal.
