What is an ellipse please help)
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.
Maybe they might use that math thing for Science.

What element does this model represent?
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.

Plzz write a small pharghraph
Question:
A 250mL Erlenmeyer flask weighing 55g contains 5g of sodium bicarbonate. To this, an excess, 15g, of acetic acid is added to the flask. While swirling, many bubbles are present. Finally, you stop swirling the flask, and the bubbles stop. You then place this flask on an analytical balance. The mass registers 73g.
How does this final mass compare with the value expected according to the Law of Conservation of mass?
Why do you believe that this comparison exists?
State the Law of Conservation of Mass. Do these results break this law? Why?
What changes, if any, could be made to the procedures in this experiment to allow a closer comparison to what the Law of Conservation would expect?

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.
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.

the Monstera Plant, in the rainforest have long, grooved leaves to drop water to the forest
floor. The excessive water that falls in the rainforest could lead to mold, so the leaves adapted to
have “drip tips” that allow the water to run off of the leaves.
What type of adaptations are these?
Monstera Plants of the rainforest. Your answer should be 3–4 sentences long.
Answer:
Theses are physical adaptations. The trees have adapted to protect themselves against mold. The “drip tips” are a new physical part of the trees, so they are physical adaptations.

Which graph shows a negative acceleration? A - B - C - D
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.

A) A car manufacturer can add coils to the electromagnet and increase the size of the magnets causing the rotational motion.
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.
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.
