describe how the boundaries between earth's tectonic plates compared with the location of most of the earthquakes
Answer:
The boundaries between Earth's tectonic plates are often marked by areas of intense seismic activity, including earthquakes. Most earthquakes occur along plate boundaries, where the movement of the plates can cause the buildup of stress in the Earth's crust. The majority of earthquakes occur at the boundaries between the tectonic plates, particularly at the edges of the lithosphere where the crust is thinnest and the most susceptible to movement. This is because the plates are constantly moving and interacting with each other, which can cause the release of built-up energy in the form of earthquakes.
Answer:
Earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. The term fault is used to describe the boundary between tectonic plates. Most of the earthquakes and volcanoes around the Pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. if it helps can you give me brainliest cause I need 10 brainliest

The writer wants to add a sentence before sentence 8 to show that the third paragraph is refuting the claim made in the second paragraph. Which sentence best accomplishes the writer’s goal?
A. Not only do babies’ eyes move side to side during REM sleep, but they also move up and down.
B. However, child psychologist David Foulkes argues that babies use REM sleep for other purposes.
C. Contrary to popular belief, REM accounts for only one of the five stages of sleep that all humans, including infants, go through.
D. On the other hand, one study conducted in 2010 indicated that babies have the ability to learn while they are sleeping.
E. Whereas adults spend only a quarter of their sleep time in the REM stage, babies average closer to half their sleep time in this stage.
Answer:
B. However, child psychologist David Foulkes argues that babies use REM sleep for other purposes.
Explanation:
Answer B
Correct. In the second paragraph, the claim is that because babies spend so much of their time in REM sleep, the stage at which dreaming occurs for adults, they most likely experience dreams. The third paragraph refutes that claim, starting with this sentence that references an expert in the field who argues that babies use their REM sleep time for “other purposes.”
The sentence which best accomplishes the writer’s goal is: B. However, child psychologist David Foulkes argues that babies use REM sleep for other purposes.
What is a claim?A claim can be defined as a sentence (statement) that is used by a writer to prove, substantiate or support an argument. This ultimately implies that, it is an assertive sentence (statement) that is expressed by a writer to prove that an argument is either true or real.
Based on the excerpt, the sentence which best accomplishes the writer’s goal is adding "However, child psychologist David Foulkes is of the strong opinion that babies use REM sleep for other purposes."

According to federal data on the year around student population, 49% of all students completing a degree in four year college enrolled in a two year college in the previous 10 years. If you take a random sample of 10 of these graduate, what is the probability that exactly 4 of them will have been enrolled in a two year college in the last 10 years?
Answer:
The probability is [tex]0.2130[/tex]
Explanation:
Let's start by defining our variable :
[tex]X:[/tex] '' Number of students completing a degree in four year college enrolled in a two year college in the previous 10 years ''
Now, let's suppose that we have an experiment compounded by a series of test. Each test result can be classified as '' success '' or '' failure ''. In each test, the success probability is called ''p'' and the failure probability is '' 1 - p ''. Both probabilities don't change from test to test and we also suppose that exists independence between each test. Therefore, the random variable [tex]Y[/tex] : '' Number of successes in n tests '' can be modeled as a binomial random variable. We write :
[tex]Y[/tex] ~ Bi ( n , p )
Where ''n'' is the number of tests and ''p'' is the success probability.
In our question,
[tex]X[/tex] ~ Bi ( n , p ) ⇒ [tex]X[/tex] ~ Bi ( 10 , 0.49 )
We can think that asking to each of the graduate is our test and whose success probability is p = 0.49
The probability function for [tex]X[/tex] is :
[tex]p_{X}(x)=P(X=x)=\left(\begin{array}{c}n&x\end{array}\right)p^{x}(1-p)^{n-x}[/tex] ; [tex]x=0,1,...,n.[/tex]
Where [tex]\left(\begin{array}{c}n&x\end{array}\right)[/tex] is the combinatorial number defined as [tex]\left(\begin{array}{c}n&x\end{array}\right)=\frac{n!}{x!(n-x)!}[/tex]
For this question, the probability function is :
[tex]P(X=x)=\left(\begin{array}{c}10&x\end{array}\right)(0.49)^{x}(1-0.49)^{10-x}[/tex] ; [tex]x=0,1,...,10[/tex]
We need to calculate [tex]P(X=4)[/tex] ⇒
[tex]P(X=4)=\left(\begin{array}{c}10&4\end{array}\right)(0.49)^{4}(1-0.49)^{6}=0.2130[/tex]
The probability is [tex]0.2130[/tex]
summarize how scientists can use seismic waves to measure and locate earthquakes
Seismic waves are waves of energy that are generated by earthquakes and travel through the Earth's crust. Scientists can use these waves to measure and locate earthquakes.
To measure an earthquake, scientists use seismographs, which are instruments that detect and record seismic waves. The seismograph produces a graph of the seismic waves, known as a seismogram, which can be used to measure the magnitude of the earthquake. The magnitude is a measure of the energy released by the earthquake and it is commonly measured by the Richter Scale.
To locate an earthquake, scientists use a technique called triangulation. This involves measuring the time it takes for seismic waves to travel from the earthquake to different seismograph stations. By measuring the time difference, scientists can calculate the distance between the earthquake and each station. By using the distance information from three or more seismograph stations, scientists can triangulate the location of the earthquake.
Another way scientists can locate an earthquake is by using seismograms to determine the depth of the earthquake. Seismic waves travel faster through solid rock than through soil or soft rock, so scientists can use the difference in arrival time of different types of seismic waves to determine the depth of the earthquake.
In conclusion, scientists use seismic waves to measure and locate earthquakes by analyzing the data generated by seismographs to estimate the magnitude, and measuring the time it takes for seismic waves to travel from the earthquake to different seismograph stations to estimate the location and depth of the earthquake.

Refer to the passage.
"It is estimated that a total of seventy thousand private tube-wells were sunk during the 1969–1970 crop season in India, which brings about 1.4 million hectares of additional land under controlled irrigation, thereby greatly expanding the food production potential. It is estimated that at present less than half of the irrigation potential of India has been developed.
If the high-yielding dwarf wheat and rice varieties are the catalysts that have ignited the green revolution, then chemical fertilizer is the fuel that has powered its forward thrust. The responsiveness of the high-yielding varieties has greatly increased fertilizer consumption. The new varieties not only respond to much heavier dosages of fertilizer than the old ones but are also much more efficient in its use. The old tall-strawed varieties would produce only ten kilos of additional grain for each kilo of nitrogen applied, while the new varieties can produce twenty to twenty-five kilos or more of additional grain per kilo of nitrogen applied. Consumption of nitrogen fertilizer in India has increased from fifty-eight thousand metric tons of nutrients in 1950–1951 to 538 thousand and 1.2 million metric tons in 1964–1965 and 1969–1970 crop cycles, respectively; and about sixty percent of this amount was produced domestically.”

Let f be a differentiable function such that f(0) = 5. 420 and f'(x) = sqrt(sin²x+x). What is the value of f(2pi)?
Differentiation
DerivativesDerivative NotationIntegration
IntegralsIntegration TechniquesIntegration Rule [Fundamental Theorem of Calculus 2]:
[tex]\displaystyle \frac{d}{dx}[\int\limits^x_a {f(t)} \, dt] = f(x)[/tex]
Let's organize what is given to us from the problem.
We are given an initial condition: f(0) = 5.420
We are given a derivative:
[tex]\displaystyle f'(x) = \sqrt{\sin^2 x + x}[/tex]
We are asked to find f(2π).
Step 2: WorkWe can first formulate a rough function using integration rules, namely the Fundamental Theorem of Calculus (2nd part):
[tex]\displaystyle f(x) = \int \limits^{x}_{a} f(t) \, dt + C_0[/tex]
where f(t) is a derivative function and C₀ is an initial condition.
Now that we have a "baseline formula", we can substitute in our f(t) derivative function, our limits, and our initial condition:
[tex]\displaystyle f'(x) = \sqrt{\sin^2 x + x} \Rightarrow f(t) = \sqrt{\sin^2 t + t}[/tex]
[tex]\displaystyle \begin{aligned}f(x) & = \int \limits^{x}_{a} f(t) \, dt + C_0 \\& = \int \limits^{x}_{0} \sqrt{\sin^2 t + t} \, dt + f(0) \\& = \boxed{ \int \limits^{x}_{0} \sqrt{\sin^2 t + t} \, dt + 5.420 } \\\end{aligned}[/tex]
∴ our general function is equal to:
[tex]\displaystyle \boxed{ f(x) = \int \limits^{x}_{0} \sqrt{\sin^2 t + t} \, dt + 5.420 }[/tex]
*Note:
There isn't an antiderivative for the general function, so you will have to input the integral into a calculator.
In order to find the value of f at 2π, we substitute x = 2π into our general function:
[tex]\displaystyle \begin{aligned}f(2 \pi) & = \int \limits^{2 \pi}_{0} \sqrt{\sin^2 t + t} \, dt + 5.420 \\& = 11.44863485704886 + 5.420 \\& = 16.868634857 \\& \approx \boxed{ 16.868 } \\\end{aligned}[/tex]
∴ [tex]\displaystyle \boxed{ f(2 \pi) \approx 16.868 }[/tex]
Answer∴ the value of f(2π) is approximately 16.868.

One way to identify limestone (calcium carbonate) is to drop a small amount of hydrochloric acid on it. A
positive test results in a fizz of carbon dioxide, water, and one other product being produced. Predict the
other product and write a balanced chemical equation for this reaction.
Answer:
Explanation:
The other product that is produced when hydrochloric acid (HCl) is added to limestone (calcium carbonate) is calcium chloride (CaCl2).
The balanced chemical equation for this reaction is:
CaCO3(s) + 2HCl(aq) -> CaCl2(aq) + H2O(l) + CO2(g)
In this equation, the solid limestone (CaCO3) reacts with the aqueous hydrochloric acid (HCl) to produce calcium chloride (CaCl2) dissolved in water, water (H2O) and carbon dioxide (CO2) as a gas. On a molar basis the reaction is 1:1 between the Calcium carbonate and hydrochloric acid which results in the balanced equation.
It's worth noting that this reaction is an example of an acid-base reaction, where the hydrochloric acid (HCl) acts as the acid, and the limestone (CaCO3) acts as the base. The acid donates a proton (H+) to the base, resulting in the formation of the products.

3. Explain the controversy over mining. Why do some people want to
continue to mine for coal while others do not.
Answer:
look below
Explanation:
The rapidly increasing use of coal in the late nineteenth century required hundreds of thousands of workers to dig that coal out of the ground, sort and load it into railroad cars, and ship it to the urban and industrial centers that consumed it. Most coalfields were sparsely populated compared to the cities they supplied. Workers had to be recruited and lured to the coal camps. Company representatives traveled across the agricultural south, recruiting Black workers from former plantation areas as a new wave of white violence followed the collapse of Reconstruction. Recruiters also went to struggling towns in Southern and Eastern Europe, paying voyage fares for men who promised to work in the coal mines on arrival. By the turn of the twentieth century, close to half a million workers—mostly men and boys, but also some women in smaller, family mines—toiled in the American coalfields.The reality of the coal camp often looked very different from what had been promised. Pay was low, and the company, which often owned miners’ housing and ran the supply store, frequently controlled their cost of living. Miners were paid by the ton, and conflicts frequently arose over the process of weighing the coal. The industry’s cyclical nature meant that mining employment also could be irregular and precarious. Coal camp living conditions were often squalid, with social life dominated by the company and basic freedoms of speech, movement, and assembly restricted by private mine guards and company-paid sheriffs.Mining coal was incredibly dangerous work. During the industrial coal boom between 1880 and 1923, more than 70,000 miners died on the job. Many more perished from occupational diseases, but weren’t tallied in official statistics. Miners were crushed to death in roof collapses, killed by gas explosions and by machinery, and more. In the first decade of the twentieth century, three major mine disasters—one each in Utah, West Virginia, and Pennsylvania—killed 201, 362 and 239 miners respectively. The West Virginia and Pennsylvania disasters occurred within two weeks of each other in 1907, during the winter period that miners called “explosion season” because the dry air amplified the dangers from methane and coal dust. More common were deadly and frequent disasters that took miners’ lives in ones and twos, but never made headlines. As urban energy intensification made cities safer, healthier, and more convenient during the Progressive Era, the everyday violence of the energy system was largely hidden from view in rural mining communities.

Answer:
the gravity keeps a huge distance between them
Most stars are not destroyed in a galaxy collision as galaxies are mostly empty space. The correct option is D.
What is galaxy?A galaxy is a massive cloud of gas and dust, as well as billions of stars and their solar systems.
Gravity holds a galaxy together. In the center of our galaxy, the Milky Way, there is also a supermassive black hole. When you look up at the stars at night, you can see other stars in the Milky Way.
If we used today's best technology to make the most basic estimate, we'd say there are 170 billion galaxies in our Universe.
Although the procedure of a galaxy collision reorganizes the stars into new structures (first tidal tails, then elliptical galaxies), because the space between stars is so large, it is extremely unlikely that even a single star collided with another star during this process.
Thus, the correct option is D.
