What is an ellipse please help)

Answers

normal oval shape traced by a point moving in a plane so that the sum of the distance from the other points is constant.

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.

(An electric motor uses regular magnets and an electromagnet to create motion. The attracting and repelling forces create rotational motion along with the electric current from the electromagnet.)
What two things can a car manufacturer do to make an electric motor stronger?

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.

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.

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

C if I am correct on this

Answer:

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.

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?
