Five stars are shown on the following H-R diagrams. Rank the stars based on their surface temperature from highest to lowest. If two (or more) stars have the same surface temperature, drag one star on top of the other(s).
All five stars appear at the same place along the horizontal axis showing spectral type.
Because spectral type is related to surface temperature, all five stars must have the same surface temperature.
Now proceed to Part C to determine how these stars vary in luminosity.
What is a Star?This refers to the heavenly body that is a natural luminous body that is visible in the sky, especially at night
Hence, we can see that based on the ranking of stars, the surface temperature of each star is taken into account, and based on their spectral type, the stars all have the same temperature.

Clouds lose their __________ when the surrounding air temperature equals the rising air temperature.
Clouds lose their stability when the surrounding air temperature equals the rising air temperature.
When vapor condenses and produces the billowing columns, the ascending air, which is still warmer than the nearby air, rises. occurs when radiation even during night cools the Earth's surface as well as the air around.
As a result, the air parcel can increase until all of the latent heat has already been released as well as the "surplus" water vapor has condensed. Hence, the fundamental factor that prevents clouds from rising is the cessation of the production of heat transfer through condensation.

The volume of gas in a flexible container at a depth of 10 m/33 ft will expand to double its original volume if taken to the surface.
What is volume:
The amount of space that a substance or object occupies.
Volume is denoted with letter V
What is a gas molecule?Generally, a gas molecule is simply defined as a combination of numbers of atoms that are connected one to another.
here, 10 m/33 feet of sea water is taken to exerts a gauge pressure that is the same pressure as the atmosphere.
This means that we add one atmosphere/bar pressure for every 10 m/33 feet you descend.
The effect of this is that,
at 10 m/33 ft absolute pressure is two ata/bar
Adding another 10 m/33 ft to this depth to make it 20 m/66 ft, puts you under under three ata/bar of pressure and so on.
Descending to a depth it means that you have double the ata/bar pressure acting on you. If you decide to resurface, the pressure on the flexible container will reduce by a factor of two.
Since volume is inversely proportional to the pressure,
If the pressure reduces by a factor of 2, then the volume will increase by a factor of two.

What is nucleotide?
Nucleotides are organic compounds made up of a phosphate and a nucleoside.They function as monomeric units of the key macromolecules found in all living forms on Earth, deoxyribonucleic acid (DNA), and ribonucleic acid (RNA), which are both nucleic acid polymers. In addition to being produced by the liver from common nutrients, nucleotides can also be received through diet. A nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group made up of one to three phosphates are the three component molecules that make up a nucleotide. Guanine, adenine, cytosine, and thymine are the four nucleobases found in DNA; uracil is used in place of thymine in RNA.On a fundamental, biological level, nucleotides are also essential to metabolism. They supply chemical energy throughout the cell in the form of the nucleoside triphosphates adenosine triphosphate (ATP), guanosine triphosphate (GTP), cytidine triphosphate (CTP), and uridine triphosphate (UTP).These are necessary for the synthesis of amino acids, proteins, and cell membranes as well as for moving the cell and its components (both internally and between cells), cell division, and other cellular processes.Nucleotides are also key cofactors in enzyme activities and take role in cell signaling (cyclic guanosine monophosphate, or cGMP, and cyclic adenosine monophosphate, or cAMP).Know more about nucleotide https://brainly.com/question/13185536

What is meant by acceleration?The rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.
Some key features of acceleration are-
Any procedure where the velocity varies is referred to as acceleration. There are just two ways to accelerate: changing your speed or changing your direction, or changing both. This is because velocity is both a speed as well as a direction.No matter how quickly you're moving, if you're not altering your direction or speed, you can't possibly be accelerating.In a car, accelerating may be accomplished by applying the gas pedal or the brakes, both of which would result in changes in speed. However, you could also turn by turning the steering wheel, which would reverse your momentum. Given that they alter velocity, any of them would be seen as an acceleration.The formula of acceleration is -

Edwin hubble was able to show that (with the exception of our nearest neighbors) the farther a galaxy is from us, the faster it is moving away from us.
Hubble ultimately demonstrated that, contrary to the widely accepted belief that the universe is static, galaxies are actually moving away from us. Hubble noticed that the light appeared to be shifted toward the red end of the spectrum by observing the light coming from distinct galaxies.
Hubble made the amazing discovery that a galaxy's redshift exactly correlated with its distance from the earth. That implied that objects farther from Earth were dispersing more quickly. To put it another way, the cosmos must be growing. In 1929, he made his discovery public.

So the correct choice is 838 J.
What is gravitational potential energy?
The energy possessed by an object due to its position from the chosen reference point when gravity is acting on that object is called gravitational potential energy.
The formula to calculate the difference in the potential energy is given by the formula,
U=m*g*h
where U is the difference in the potential energy, m is the mass, g is the acceleration due to gravity, and h is the height difference between the initial height and the final height.
The height difference is given by the formula,
h=h2-h1
where h2 is the final height and h1 is the initial height.
Given that the initial height is 1.30 m and the final height is 3.20 m, substitute h1=1.30 m and h2=3.20 m in the formula of height to calculate the height difference.
h=3.20-1.30
