If one were 230 kilometers above sea level, one would be in the part of the atmosphere known as the ________.

1 answer:

8 0

The Earth's atmosphere consists of 6 layers going up.

Troposhere is the closest layer. From the Earth's surface it extends up into the atmosphere about 8-15 meters.

Stratosphere extends above the troposphere about 50 km from the ground.

Above the stratosphere is the Mesosphere which goes up to 85 km above the surface of the Earth.

Then we have the Thermosphere which goes up to 500 to 1,000 km above ground.

The Exosphere, which extends from the thermosphere to about 100,000km to 190,000 km.

The ionosphere is a layer that is not exactly as distinct as the others. It overlaps the mesosphere and exosphere.

Now if you were 230 kilometers above sea level, then you would be in the 4th layer of the atmosphere, or the Thermosphere because it starts at about 86 km above sea level and extends to about 500 to 1,000 km above sea level.

I believe the answer would be C because potential energy is affected by height and mass. The truck in photo C is the highest and has a lot of mass.

What are the three rules for writing the electron configuration of elements

astraxan [27]

Answer:

The aufbau principle

The Pauli exclusion principle

Hund's rule of maximum multiplicity

Explanation:

The aufbau principle:

The fundamental electronic configuration is achieved by placing the electrons one by one in the different orbitals available for the atom, which are arranged in increasing order of energy.

The Pauli exclusion principle:

Two electrons of the same atom cannot have their four equal quantum numbers. Because each orbital is defined by the quantum numbers n, l, and m, there are only two possibilities ms = -1/2 and ms = +1/2, which physically reflects that each orbital can contain a maximum of two electrons, having opposite spins

Hund's rule of maximum multiplicity:

This rule says that when there are several electrons occupying degenerate orbitals, of equal energy, they will do so in different orbitals and with parallel spins, whenever this is possible. Because electrons repel each other, the minimum energy configuration is one that has electrons as far away as possible from each other, and that is why they are distributed separately before two electrons occupy the same orbital.

The main illustration in the video shows the life track of a one-solar mass star. Each point along this track represents _______

REY [17]

Each point along the track of one solar mass star represents the star's surface temperature and luminosity at one time.

<h3>What is the one-solar mass star?</h3>

A star having a mass equal to the mass of the Sun is called a one-solar mass star.

Its life track shows the luminous intensity as well as the surface temperature.

How do two objects at different temperatures attain thermal equilibrium?

Lady bird [3.3K]

Answer:

C.As the two objects touch, thermal energy flows as heat from the warmer block to the colder block until particles in both blocks move at the same rate and reach the same temperature.

Explanation:

Heat is the transfer of thermal energy from an object at higher temperature to an object at colder temperature.

The temperature of an object is a measure of how fast the particles in the object move: the higher its temperature, the faster the particles move, the higher the average kinetic energy of the particles in the object. As a result, the particles of the object at higher temperature tend to transfer more energy (called thermal energy) to the particles of the object at colder temperature by colliding with them: this process continues until the particles of the colder object reach the same average kinetic energy as the particles of the warmer object, and this means that the two objects have reached the same temperature.
