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.

What three psychologists agreed that psychology ought to be solely concerned with objective, observable behavior? 1. Ivan Pavlov 2. B.F. Skinner 3. Sigmund Freud 4. John Watson 5. Edward B. Titchener 6. William Wundt
Ivan Pavlov, 2. B.F. Skinner, and 4. John Watson all agreed that psychology should be solely concerned with objective, observable behavior. Pavlov was a Russian physiologist who is known for his work on classical conditioning, in which he demonstrated that animals can learn to associate certain stimuli with specific responses. Skinner was an American psychologist who developed the theory of operant conditioning, which states that behavior is determined by its consequences. Watson was an American psychologist who is known for his work in the field of behaviorism, which emphasizes the study of observable behavior rather than mental processes
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.
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.”

Answer:
E. It establishes the conventional view about whether babies dream in order to show how the argument of the passage departs from this understanding.
Explanation:
Answer E
Correct. The function of the second paragraph is to establish the conventional view that babies must dream because they experience REM sleep. It is important to explain this position because it helps readers understand how the passage’s argument—that babies probably do not dream because their brains are occupied with other activities and lack the capacity for visual imagination—relates to other points of view on the topic.

meters per second
The average velocity for Usain Bolt is given as follows:
10.42 meters per second.
How to obtain the velocity?The measures in this problem are obtained considering the relation between velocity, distance and time.
The relation between velocity, distance and time states that the velocity is obtained by the quotient of the distance by the time, as follows:
v = d/t.
In which:
v is the velocity.d is the distance.t is the time.The parameters for this problem are given as follows:
Distance of 100 meters.Time of 9 and (3/5) seconds = 9 + 3/5 = 9 + 0.6 = 9.6 seconds.(for the conversion of a mixed number to decimal, we add the integer part to the fractional part).
Hence the average velocity is obtained as follows:
100/9.6 = 10.42 meters per second.

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.

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.

Write an essay in which you come to a definitive conclusion about how members of Congress decide to vote. Support your conclusion with information from The Lanahan Readings excerpts listed on the assignment page and outside research.
Answer:
Members of Congress often face difficult decisions when it comes to voting on legislation. There are many factors that can influence how they decide to vote, and it is not always easy to predict how a particular member will vote on a given issue.
According to The Lanahan Readings, one important factor that can influence how members of Congress vote is their party affiliation. Members of Congress are more likely to vote in line with their party's position on an issue, especially if the issue is considered important to the party. For example, a Republican member of Congress is more likely to vote in favor of a bill supported by the Republican Party, even if the bill is not necessarily in the best interest of their constituents.
Another factor that can influence how members of Congress vote is their personal beliefs and values. Members of Congress are elected to represent the interests of their constituents, but they also bring their own personal experiences and values to their decision-making process. For example, a member of Congress who is strongly pro-life may be more likely to vote against a bill that expands access to abortion, even if their constituents support the bill.
In addition to party affiliation and personal beliefs, members of Congress may also be influenced by the views of their constituents. If a large number of their constituents support or oppose a particular bill, members of Congress may feel pressure to vote in line with their constituents' views.
In conclusion, there are many factors that can influence how members of Congress decide to vote. Party affiliation, personal beliefs, and constituent views are all important considerations that can shape their voting decisions. Ultimately, the decision to vote for or against a particular bill is a complex one, and it is not always easy to predict how a member of Congress will vote.
