11) Maricela and Joaquim are standing on the floor very close to each other. They are not touching. Which of the following statements is true about the forces that are present?
A) The is a large gravitational repulsion between the two students.
B) There is a large gravitational attraction between the two students.
C) There is a small gravitational repulsion between the two students.
D) There is a small gravitational attraction between the two students.
Answers
Answer:
D
Explanation:
Anything with mass has gravitational attraction. Maricela and Joaquim have mass, which means they have gravitational attraction towards one another. Why are they not touching/getting close to one another? It is because both of them have a tiny amount of gravitational pull. In order for this to be considered a large amount of gravity (or B) , they would both would have to have a significant amount of mass, such as the moon or sun. The reason the answer is not A or C is because "gravitational repulsion" doesn't exist.

Answer/Explanation:
Is Fossil Fuel Overuse threatening your health? Pollution that not only can harm health but also foster climate changes. The Overuse of fossil fuel damages our health. For Instance, Burning fossil Fuel increates a carbon dioxide; to much CO_2 is harmful to our health. This Proves that Fossil fuel can harm our health. Burning fossil fuels could lead to developmental delays in children. This tells us it can be very harmful for children. To much Co_2 can cause children to have adhd. In the text it states children exposed to air pollution from fossil fuels have a significantly greater chance of developmental.Fossil fuels burning cause global warning that makes it difficult to grow crops. This reveals that Fossil fuels can be harmful for the environment. Burning fossil fuels can cause extreme weather and it can cause people to lose their homes and lives.

Which graph shows a negative acceleration? A - B - C - D
Answers
Answer:
C or D, as A and B are going upward and you need NEGATIVE acceleration so it has to be going down, though I believe it is C, but you'll have to confirm it.
Explanation:
In the given situation, Graph B shows negative acceleration because the velocity is decreasing. The option C is correct.
What is acceleration?The term acceleration is defined as the rate of change of an object's velocity with respect to time.
The change in rate of displacement is called as velocity. The rate of change of velocity is defined as acceleration.
It includes both magnitude and direction, velocity is a vector quantity. Because it is simply the rate of change of velocity, acceleration is also called a vector quantity.
The slope of the line on the velocity-time graph reveals the object's acceleration. An upward slope represents positive acceleration, which means the object is moving faster.
A downward slope represents negative acceleration, which indicates that the object is slowing down.
Thus, the option C is correct.

What element does this model represent?
Answers
Answer:
[tex]$\tex$ Option 2: Aluminum (Al)[/tex]
Explanation:
When we are given Bohr models, we will be given a circle with rings surrounding it. The circle in the center of the model represents the nucleus, which contains the neutrons and the protons. The rings will have spherical structures that are attached to them in an orderly fashion - these model the electrons of an atom.
Protons are positively-charged subatomic particles that also identify the atom's chemical identity and atomic number. Using the number of protons, we are able to identify the element. The neutrons are the neutrally-charged subatomic particles that give an atom its weight. When you look at a traditional periodic table, you'll see that the square that houses an element has its symbol, atomic number, and atomic mass. The atomic mass is equivalent to the sum of the protons and neutrons.Electrons are negatively-charged subatomic particles that give an atom its overall charge. In order for an atom to be stable and neutral, the electrons must equal the protons. Otherwise, we have an unstable atom called an ion with either a positive or a negative charge. This is dependent on whether an atom has gained or lost electrons.When we reference the model, we will see that there are 13 "p" and 14 "n" within the green circle. The "n" refers to neutrons and the "p" refers to protons. We can also count the red spheres and make quick observations about these: there are 2 red spheres on the innermost ring - for simplicity reasons, we will title this ring as r = 1. There are 8 red spheres on the middle ring - this ring will be titled r = 2. Finally, we can see that there are 2 more electrons in the outermost ring - this ring will be titled r = 3.
Now, because we have 13 protons, we know that the protons are equivalent to the atomic number.
If we check the periodic table, we will see that Silicon (Si) has an atomic number of 14. This doesn't match the number of protons, so we can rule out that a silicon atom is not the element shown.When we use the same process and check aluminum, we discover that Aluminum (Al) has an atomic number of 13. Since the number of protons and the atomic number are equal, we can conclude that this is the element.If we check Helium (He), we see that it has an atomic number of 2, so this is definitely not our element in question.Now that we have concluded that Aluminum is our element, we can check this to be sure. If we use the formula m = n + p (where m is the atomic mass, n is the neutrons, and p is the protons), we can check to be sure we have selected the right element.
The given mass of aluminum on the periodic table is 26.982 atomic mass units. We round to the nearest integer when it comes to this, so we round 26.982 up to 27 even.
Now that we have determined the atomic mass and we are given the number of both protons and neutrons, we can act as if we weren't given the amount of neutrons and only the mass and amount of protons. We can then use the equation to solve for the amount of neutrons and check that the selection we made is correct.
Steps
Substitute 27 for m and 13 for p.Subtract 13 from both sides to isolate the n and place the constants on the same side of the equation.Combine like terms by taking the appropriate operations (in this case, this is subtracting 13 from 27).Finally, because we are solving for n, you can reverse the equation (place the constant on the right and place the variable on the left; i.e., 72 = x → x = 72).[tex]27 = n + 13\\\\27 - 13 = n\\\\14 = n\\\\n = 14[/tex]
The work we just performed will allow us to confirm that because we solved for 14 neutrons, Aluminum (Al) is indeed the element represented by the model.
Hope this helps! :)

B) The car manufacturer can add coils the the electromagnet and decrease the size of the magnets causing the rotational motion.
C) The car manufacturer can remove coils from the electromagnet and increase the size of the magnets causing the rotational motion.
D) The car manufacturer can remove coils from the electromagnet and decrease the size of the magnets causing the rotational motion.
Answers
Answer:
The answers A i did the test
A car manufacturer can add coils to the electromagnet and increase the size of the magnets causing the rotational motion and the correct option is option A.
What are electromagnets?Electromagnets are made out of a coil of wire (wire curled in series).
This is more effective in producing a magnetic field than just a wire running straight.
This effect can be strengthened by winding a wire tightly around a powerful core made of magnetic material, such as iron.
The strength of the magnetic field is proportional to the number of turns made around the iron core and how tightly they are wrapped around.
Therefore, a car manufacturer can add coils to the electromagnet and increase the size of the magnets causing the rotational motion and the correct option is option A.
