The half-lives for the radioactive decay of various elements are listed in the table below.
Parent Isotope Daughter Isotope Half life
Carbon-14 Nitrogen-14 5,730
Uranium-235 Lead-207 710 million
Potassium-40 Argon-40 1.25 billion
Required:
a. Suppose you discovered a meteorite that contains a small amount of potassium-40 and its decay product argon-40. You determine that 1/8 of the original potassium-40 remains; the other 7/8 has decayed into argon-40. How old is the meteorite?
b. A piece of cloth was painted with organic dye 40,110 years ago. What percentage of the original carbon-14 in the organic dye remains after all this time?
c. The oldest minerals found on Earth are zircons. One isotope used to measure their age is uranium-235. A single crystal contained 200 nanograms of uranium-235 when it first formed. How much uranium-235 does the crystal still contain if it formed 4.26 billion years ago?
d. Is radiocarbon dating a useful tool for determining the age of the solar system? Explain why or why not
Answer:
See solution and explanation below
Explanation:
a) From;
N/No = (1/2)^t/t1/2
1/8 = (1/2)^t/1.25 * 10^9
(1/2)^3 = (1/2)^t/1.25 * 10^9
3 = t/1.25 * 10^9
t = 3 * 1.25 * 10^9
t = 3.75 * 10^9 years
b)
N/No = (1/2)^40,110/5,730
N/No = (1/2)^7
N/No = 1/128
percentage remaining after 40,110 years = 1/128 * 100 = 0.78%
c) N/200 * 10^-9 = (1/2)^4.26 * 10^9/0.710 * 10^9
N/200 * 10^-9 = (1/2)^6
N/200 * 10^-9 = 1/64
64 N = 200 * 10^-9
N= 3.125 * 10^-9 g
d) Radiocarbon dating can not be used to determine the age of the solar system since the solar system is as old as the universe and was formed billions of years ago. Radiocarbon dating can only be accurately used to obtain the age of objects of plant or animal origin between 1000 - 10000 years old.

What has given Britain a geographic advantage ?
Answer: The United Kingdom is a sovereign state located off the north-western coast of continental Europe. With a total area of approximately 248,532 square kilometres (95,960 sq mi), the UK occupies the major part of the British Isles archipelago and includes the island of Great Britain, the north-eastern one-sixth of the island of Ireland and many smaller surrounding islands.[1] It is the world's 7th largest island country.[2] The mainland areas lie between latitudes 49°N and 59°N (the Shetland Islands reach to nearly 61°N), and longitudes 8°W to 2°E. The Royal Observatory, Greenwich, in south-east London, is the defining point of the Prime Meridian.
The UK lies between the North Atlantic and the North Sea, and comes within 35 km (22 mi) of the north-west coast of France, from which it is separated by the English Channel. It shares a 499 km international land boundary with the Republic of Ireland.[3][4] The Channel Tunnel bored beneath the English Channel now links the UK with France.

David observed properties of four different compounds, only one of which is an ionic compound. His observations are shown in the chart. A 2-column table with 4 rows. The first column labeled compound has entries W, X, Y, Z. The second column labeled observations has entries is a hard solid, melts at 44 degrees C, has a molecular structure; is a brittle solid, does not conduct electricity in water, has a crystal structure; is a hard solid, conducts electricity, has a molecular structure; is a brittle solid, melts at 801 degrees C, has a crystal structure. Which is most likely the ionic compound? W X Y Z
Answer:
Z
Explanation:
As we know, ionic compounds are characterized by its brittle and hard nature. Such compounds possess extremely high boiling, as well as, melting points and therefore, more conducive. As per the question, 'Z' is most likely the ionic compound because it possesses the above characteristics of being large in mechanical force(brittle solid, melts at 801 degrees C, has a crystal structure). Thus, option D i.e. 'Z' is the correct answer.
Answer:

Which statement best describes the theory of plate tectonics?
Plates sometimes move closer to one another.
Sections of Earth that shift are part of Earth’s asthenosphere.
Sections of Earth’s continents are in slow, constant movement.
Parts of the ocean floor move as they are carried by rift valleys.
Answer:
C Sections of Earth’s continents are in slow, constant movement.
Explanation:
Parts of the ocean floor move as they are carried by rift valleys is the statement best describes the theory of plate tectonics. Hence, option D is correct.
How rift valleys are formed?A rift valley is a lowland area created by the separation of Earth's tectonic plates. Both on land and at the bottom of the ocean, rift valleys are produced as a result of the spreading of the seabed.
The four largest active continental rift valleys on Earth are the East African Rift, the Baikal Rift Valley, the West Antarctic Rift, and the Rio Grande Rift.
Rift valleys are typically long and narrow, some of them stretching hundreds of kilometers. Due in great part to volcanic deposition and marine or lacustrine sedimentation, their floors are comparatively level. Rift valleys have sharply sloping slopes that resemble terraces and stairs.
Thus, option D is correct.

Explanation:
France first colonized Canada because of the __________. A. gold mines B. fur trade C. sea ports D. slave market Please select the best answer from the choices provided A B C D
Answer:
B
Explanation:
fur trade
Answer:
France first colonized Canada because of the fur trade.
Explanation:
When the Spanish discovered the Americas, the word about it quickly spread across Europe. Fearing that the Spanish may occupy the entire territory and gain a huge advanatge over them, the other naval powers of Europe were quick to react and sent their own expeditions with the purpose to create their own colonies. One of those countries was France.
France first focused on colonizing what is now Canada. While it did not colonize the entire territory of modern-day Canada, it did manage to get the strategically important areas in southern Canada and southeastern Canada. While the other colonial powers had their focus on creating large plantations with cash crops, the French were not in such a situation to be able to profit from it because of Canada's climate, so they focused on something else that was in high demand and paid well, fur. Canada had an abundance of animals that had highly valuable fur on the market, so the French played wisely and made good relations with the locals which hunted the animals for them in exchange for other goods.

The map shows a top view of the Mississippi River. The gap between lines 1 and 2 shows how much Saint Anthony Falls receded between 1680 and 1766. The gap between lines 3 and 4 shows how much the falls receded between 1856 and 1876. At what rate (on average) did the falls recede during each of these time spans? Express your answer in units of feet per year. Did the rate increase or decrease from one time span to the next?
Hint: Determine how many years passed between lines 1 and 2 and between lines 3 and 4 to help you find your answers.
Answer:
500 year per each they possibly increased and decreased
Explanation:
Answer:
The time span between 1680 and 1766 (lines 1 and 2) is 86 years: 1766 − 1680 = 86 years. During this time, the falls receded an average of 5.8 feet per year: 500 feet ÷ 86 years = 5.8 feet per year.
The time span between 1856 and 1876 (lines 3 and 4) is 20 years: 1876 − 1856 = 20 years. During this time, the falls receded an average of 25 feet per year: 500 feet ÷ 20 years = 25 feet per year.

O Guiana
O Pampas
please help :>
Answer:
Patagonia
Explanation:
it is dry and hot during the summer which is the Arid part of the climate. yet during the winter and is cold and dry which is why it is cool steppe climate.
because cool steep climate means that it is an environment with warm to hot summers and cool to very cold Winters
the reason it is cold in the winter in Patagonia is because the Westerly winds brought cold air from Antarctica and funneled it into Southern Patagonia
Patagonia is warm during the summer reaching around 72 degrees Fahrenheit. but I cannot find explanation to why it is warm during the summer in Patagonia

Using complete sentences, explain how the increasing popularity of the automobile led to the growth of suburbs.
Answer:
The automobile made living in the inner city less attractive and living outside the city more attractive. The increasing use of automobiles in the city led to larger streets and roads. Increased traffic on more roads made walking less pleasant or practical. City zoning encouraged commercial development with parking space for vehicles. Freeways were planned to meet demand. Because of the automobile, people who worked in the city were able to travel greater distances from their home to work every day. As zoning and traffic made the cities less desirable, people built their homes in suburban areas outside the city.

When civilizations first moved from hunting-and-gathering subsistence to agricultural subsistence, people were able to cultivate other aspects of their culture. Describe three aspects of society that emerged from this transition.
Answer:
the aspects are that some people have it and dont
Answer:
The division of labor occurred as surplus food supplies provided people with greater stability and security. This development enabled societies to become more sophisticated and to develop culturally. Complex social classes emerged; many social classes developed, including a ruling nobility and a priestly class. Other classes, such as artisan classes, developed based on skills. Organized religion also emerged. Religion was commonly polytheistic, initially with gods who focused on basic human desires and fears like fertility, death, and the weather. Recordkeeping and the first writing systems were other developments. Governments and tax collection came into existence, and cities organized military units and created military structures, such as moats, to protect themselves from invaders.
