Answer:

Option (3)

Explanation:

Aurora refers to those northern and southern light observed in both the poles of earth. At the poles, when sunlight comprised of numerous charged particles are emitted from the sun are incident on the atmosphere of the earth, it reacts with the earth's magnetic field and results in the rapid movement of electrons within the atoms, from a region of lower energy state to a higher state. After sometimes when these electrons are back into the lower-energy state then photons are released in the form of beautiful lights which are known as aurora.

These lights are known as aurora borealis when observed in the north pole, and aurora australis when observed in the south pole.

Thus, the correct answer is option (3).

Answer:

a) Tc = 750 [N]  ;b) See the explanation below.

Explanation:

To solve this problem, we first need a graphical explanation of this, as well as knowing the corresponding questions. Therefore, a search was carried out in google, in the attached image we will find a graphical description of the problem.

b)

The solution of this type of problem corresponds to the use of Newton's third law, applying static which tells us that the sum of the forces in a system in equilibrium without movement must be equal to zero.

a)

In this way we can find by means of a sum of forces on the y axis equal to zero:

- 850 - 450 + 550 + Tc = 0

Tc = 750 [N]

What are properties of a liquid?
Oksi-84 [34.3K]

Answer:

Pressure

Surface

Flow

Fluency

Explanation:

*Surface

The surface tension is the force with which the surface molecules of a liquid are attracted to bring them inside and thus decrease the surface area.

*Flow

It is defined as resistance to flow. The viscosity of a liquid depends on the intermolecular forces:

-The higher the intermolecular forces of a liquid, its molecules have a greater difficulty moving between them, therefore the substance is more viscous.

-Liquids that are made up of long, flexible molecules that can bend and tangle with each other are more viscous.

* Pressure

if the molecules of the liquid have a greater intensity of intermolecular force, then they will be trapped in the liquid and will have less facility to pass into the gas phase.

    on the contrary to lower intensity of intermolecular force, then the molecules can escape more easily to the gaseous state.

*Fluency

This property allows liquids to easily pass through a hole regardless of size, as long as this hole is at a lower or the same level of the container where the liquid is stored.

This property indicates the deformability of a liquid which is very wide without requiring mechanical stress.
