Which of the following best describes the streak for metallic gray specular hematite (Fe2O3)?

a. red-brown
b. yellow
c. gray
d. black

Answers

Answer 1

The rate of consumer goods ownership reflects a country's  internal distribution of wealth.

Explanation:

The levels of internal distribution of wealth allow us to show how the economic total produced by a country is distributed among the total of its population: thus, if the goods produced in the country are distributed equitably, this accounts for a distribution of the positive wealth, that is, where there are no great inequalities between citizens.

(40 points!!! brainliest for first answer) Using complete sentences, explain what the charts above say about industry, service, among us, and agriculture in Europe.

Answers

Answer: The charts above help show that the wealthier countries (France, Italy, and Poland) have more developed economies, which is why agriculture isn't as big a part of the economy as it is in Romania, for example. Because the economies of the first 3 countries are developed, they can be considered Stage 4 countries, or countries that have developed economies and stable populations. Romania, on the other hand, still depends on agriculture for almost 1/3 of its total economic output, and could therefore be classified as a stage 3 country (a country with a developing economy and a stabling population). In summary, France, Italy, and Poland have a more developed economy than Romania, and this shows by what economic activities go on in each country to make up for the data shown.

You have an isotope with a half-life of 200 years How much of the original material
is left after 600 years?

Answers

Answer:

[tex]\frac{1}{8}[/tex] of its original size would be left

Explanation:

The half life of the isotope is the time required for it to decay to half of its original size.

Half life of the isotope = 200 years

So that, after 600 years the material that would be left would be;

let the original size of the material be represented by x.

200 years = [tex]\frac{1}{2}[/tex] x would remain

400 years = [tex]\frac{1}{4}[/tex] x would remain

600 years = [tex]\frac{1}{8}[/tex] x would remain

Thus after 600 years, [tex]\frac{1}{8}[/tex] of its original size would be left.

With Poland overrun by German armored columns now poised to strike at France, and China under assault by Japan, Americas commanders had to prepare the US military for war. The problem was not a dearth of troopsafter Adolf Hitlers blitzkrieg rolled through Poland in September 1939, Congress had mobilized the National Guard and Reserve and approved an increase in the size of the Army. It was that the existing troops were poorly trained or not trained at all.No one was more acutely aware of this than Army Chief of Staff General George C. Marshall. A student of history, Marshall was certain American boys were as courageous as any German or Japanese soldier, but they lacked sufficient training and combat experienceand time was short. Marshall concluded that what Americas burgeoning ranks needed was a complex training exercise, an exacting test in an environment that would closely approximate the realities of the battlefield.Louisiana Maneuvers by Mark PerryWhat was General Marshalls biggest concern about the US Army in 1940?There were not enough soldiers enlisted in the military.Most soldiers had received little preparation on how to fight a war.There was no land available to complete combat training exercises.American troops were already struggling in the fight against Germany. a sample of a composition with 250-350 words about a visit to a home were you felt unwelcome pls ,pls,plssss help my
