Analysis of a rock sample shows that it contains 6.25% of its original uranium-235. How old is the rock? How do you know?

Answers

Answer 1

The rock is 2100 million years old by computing its half life.

Explanation:

The half life of Uranium 235 is 700 million years. it is an extremely radioactive component and produces a large amount of nuclear energy in reactions.

Half life of a product means that it will decompose into half of what it was in the time that is written so we can see that the sample would be halved in 700 million years of time.

The rock now retains only 6.25% of its original mass which means that it is 1/16th of what it used to be.

So, if the half life of the product makes the product out to be 1/2 in 700 million years

It means that to get to 6.25 it would require 3 more half lives which results that

3 times 700 million years

2100 million years.

Answer 2

The age of the rock, based on the uranium-235 content indicating 6.25% of its original amount remaining, is approximately 2816 million years.

Given that the rock sample contains 6.25% of its original U-235, we can infer that 93.75% of the original U-235 has decayed into lead-207.

Let's denote:

- ( N_0 \) as the original amount of U-235 in the rock.

- ( N ) as the current amount of U-235 in the rock.

According to the information provided:

[tex]\[ \frac{N}{N_0} = 0.0625 \][/tex]

This implies:

[tex]\[ \frac{N_0 - N}{N_0} = 0.9375 \][/tex]

This ratio (0.9375) represents the fraction of U-235 that has decayed into Pb-207.

Now, to find the age of the rock (\( t \)), we use the relationship involving the half-life:

[tex]\[ \left( \frac{N}{N_0} \right) = \left( \frac{1}{2} \right)^{\frac{t}{T_{1/2}}} \][/tex]

where [tex]\( T_{1/2} \)[/tex] is the half-life of U-235 (704 million years).

Substituting [tex]\( \frac{N}{N_0} = 0.0625 \):[/tex]

[tex]\[ 0.0625 = \left( \frac{1}{2} \right)^{\frac{t}{704 \text{ million years}}} \]\\[/tex]

To solve for t

[tex]\[ \log_2(0.0625) = \frac{t}{704 \text{ million years}} \][/tex]

[tex]\[ \log_2(0.0625) = \log_2\left( \left( \frac{1}{2} \right)^4 \right) = 4 \cdot \log_2\left( \frac{1}{2} \right) = 4 \cdot (-1) = -4 \][/tex]

[tex]\[ \frac{t}{704 \text{ million years}} = -4 \][/tex]

[tex]\[ t = -4 \cdot 704 \text{ million years} \][/tex]

[tex]\[ t = -2816 \text{ million years} \][/tex]

Therefore, the age of the rock, based on the uranium-235 content indicating 6.25% of its original amount remaining, is approximately 2816 million years.

This calculation assumes that the rate of decay has been constant over time, which is a foundational principle of radiometric dating. Thus, we can determine the age of the rock with confidence based on the principles of radioactive decay and the half-life of uranium-235.

——Wright is Emmett tills uncle

Answers

Answer: Mose Wright

Explanation:  In 1955, Emmett was stocky and muscular; he weighed about 150 pounds (68 kg) and stood 5 feet 4 inches (1.63 m) tall. Mamie Till Bradley's uncle, 64-year-old Mose Wright, visited her and Emmett in Chicago during the summer and told Emmett stories about living in the Mississippi Delta.

Was glad to help have a great day!

Final answer:

The historical context of Emmett Till's murder in 1955 provides a harrowing look into the racial violence present during that era, as well as the direct involvement and suffering of Emmett's family, including his uncle. Emmett's death became a catalyst for the civil rights movement, and its impact is still seen today in the ongoing fight against racial prejudice.

Explanation:

The tragic story of Emmett Till, a young African American boy, has become a historical marker in the context of racial violence in the United States. In 1955, Emmett, then 14 years old, was visiting his relatives in Mississippi when an incident at a local grocery store led to his brutal murder. Emmett was accused of whistling at a White woman, which resulted in him being kidnapped by the woman's husband, Roy Bryant, and his half-brother J.W. Milam. Despite a lack of evidence, Emmett was viciously beaten and lynched. His uncle's house was where Emmett was taken from, marking a direct familial connection to the horror that unfolded.

Emmett's mother, Mamie Bradley, made the powerful decision to have an open casket funeral in Chicago to expose the atrocities her son suffered. This decision was a catalyst in the civil rights movement of the time, as Emmett Till's death highlighted the racial injustices of the era. Emmett's murder, and the failure to convict his killers, galvanized public opinion and became a touchstone for civil rights activists, including Medgar Evers who fought tirelessly for justice in the case.

Years after Emmett's murder, its memory continues to resonate, as evidenced by acts of disrespect towards commemorative signs, underscoring the ongoing struggle against racial prejudice and the importance of remembering Emmett Till's story.

Explanation:

I hope this helps you. Have a good day.

Final answer:

A symbol represents something else by association. Symbols can bear distinct meanings in different cultures, as seen with the pentagram and swastika. Lord Pakal was a significant Maya ruler, and his sarcophagus is of great anthropological interest. Dance and music are important anthropological tools due to their rich cultural expressions.

Explanation:

A symbol is a mark, sign, object, or image used to represent something else by association, resemblance, or convention. Symbolism varies across different cultures and can change over time.

An example of the differing symbolism is the swastika, which has been used in Hinduism and Buddhism as a sacred symbol of peace and good fortune, while in contemporary Western contexts, it is most commonly associated with the atrocities of the Nazi regime during World War II.

The displacement characteristic of symbols suggests that they can stand for something that is not immediately present in the physical environment, allowing communication about abstract concepts, absent entities, or historical events. Symbols can thus convey complex ideas and emotions.

Observing a swastika in Navaho weaving indicates that symbols can have different meanings in disparate cultural contexts independent of each other. This highlights the concept of cultural relativism, where a symbol's meaning is relative to the cultural context it is found in.

The pentagram, a five-pointed star, has a range of symbolic meanings. In Western esoteric traditions, it has been associated with the five elements and protection against evil. In some Eastern traditions, the pentagram represents the five directions and the five senses.

Lord Pakal was a Maya ruler in the city of Palenque during the seventh century. His sarcophagus is renowned for its intricate carvings that reveal information about Mayan cosmology, theology, and rulership, making it a vital source for understanding ancient Mayan civilization.

Dance and music are considered elemental components for anthropological analysis as they involve complex social and cultural expressions, allowing researchers to understand social structures, identities, and cultural narratives through performance.

C) Hold a meeting to get ideas from citizens about how to pay for the school.
D) Send letters to state representatives to ask them to help pay for the school.

Answers

Answer:

a

Explanation:

The most effective method for a city to fund a new school is by holding a meeting to gather ideas from citizens (Option C), promoting community involvement and innovative funding solutions.

To solve the problem of how to pay for a new school, there are various approaches a city could take. One possible solution is C) Hold a meeting to get ideas from citizens about how to pay for the school. This option encourages community involvement and allows for a range of ideas and perspectives that could lead to innovative funding solutions. It aligns with practices of local government engagement and promoting civic participation in important decisions affecting the community.

Other approaches could involve reaching out to higher levels of government for support, as suggested in options B) and D), but these are less direct and involve navigating more complex bureaucratic structures. Option A) is less common as judicial decisions are typically not about funding solutions but rather legal interpretations or dispute resolution.

Involving citizens can also lead to a better understanding of the financial complexities involved in local education funding. As noted in background information, state governments often contribute a significant portion of funding for education, which citizens might not be aware of, and their involvement could lead to a more educated electorate and greater support for proposed funding solutions. Moreover, local economies are usually intertwined with state funding, and a balanced budget is necessary for maintaining financial stability.

The items that were part of the Reconstruction Era in the United States include the 13th Amendment, Black Codes, military occupation of southern states, and the founding of the Ku Klux Klan. The 13th Amendment, ratified in 1865, abolished slavery throughout the United States. Black Codes were restrictive laws passed in the southern states with the intent to limit the freedom of African Americans and ensure their availability as a cheap labour force after the Civil War. Additionally, the southern states were under military occupation during Reconstruction to enforce the new laws and protect the rights of newly freed slaves. The Ku Klux Klan was founded as a white supremacist group that violently opposed the rights of African Americans during the Reconstruction Era.

Suffrage for women and the book Uncle Tom's Cabin, although important in American history, were not part of the Reconstruction period. Suffrage for women was realized with the passage of the 19th Amendment in 1920, which was beyond the end of Reconstruction. Uncle Tom's Cabin was published in 1852, before the Civil War and Reconstruction.

Constantinople was allowing paintings of Jesus, Virgin Mary, and the saints to be put in the churches or exposed publicly. Rome was not fond of this at all, and it was prohibiting such acts as it saw them as inappropriate.

Officially this became the theme that separated the two sides and resulted in the formation of the Catholic Church and the Orthodox Church. It has to be taken in account though that another major reason for the split was having more power, as the two cities were competing against each other as to which one is the center of power.
