Answer:
1. Main Sequence - middle life 17
2. red
3. blue
4. White dwarf stars are much hotter than Red Supergiants 15. List the color of the stars from hottest to coldest: Blue, White, Yellow, Orange, Red 16.
5. red giants
Explanation:
Main sequence stars have a Morgan-Keenan luminosity class labeled V. red giant and supergiant stars (luminosity classes I through III) occupy the region above the main sequence. They have low surface temperatures and high luminosities which, according to the Stefan-Boltzmann law, means they also have large radii. White dwarf stars are much hotter than Red Supergiants 15. List the color of the stars from hottest to coldest: Blue, White, Yellow, Orange, Red 16. The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes. The lowest temperature stars are red while the hottest stars are blue. Astronomers are able to measure the temperatures of the surfaces of stars by comparing their spectra to the spectrum of a black body. Most stars, including the sun, are "main sequence stars," fueled by nuclear fusion converting hydrogen into helium. ...
As stars begin to die, they become giants and supergiants (above the main sequence).

PLEASE HELP :) THANK YOU Geologic processes change Earth's surface on varying scales of space and time. They range from rapid to very slow; from large to microscopic.
How does the time scale of slow geologic processes affect human perception of landforms on Earth? Provide details to support your answer.
Answer:
Human change the surface by mining it, falting it for land, we remove tree,plants, soil,mud, to build space for buidlings, farms, and etc hopes this help
Explanation:
What are air masses, and how do they work?
NEED HELP ASAP!
Answer:
Need help? I'll give it to you!
Explanation:
Air masses are formed when air stagnates for long periods of time over a uniform surface. The characteristic temperature and moisture of air masses are determined by the surface over which they form. An air mass acquires these attributes through heat and moisture exchanges with the surface.

1. Omar is sliding along the school corridor. Draw a picture of Omar sliding along the floor. Add a force arrow to show the force of friction acting on Omar.
2. Press your hands very gently and rub them. Now press much harder and rub again. Describe what you observe. What does this tell you about the force of friction?
Answer:
well all you would have to do is draw a picture of him sliding and an arrow
and as for the second one rub your hands together and tell them what you see and then explain if it was easy to do or if you had troubles because the force of friction will make your hands warm up which is why you see them rub their hands together in movies
Answer:
1. The Speed is 390
2. The Frequency is 425 Hz
3. The Wavelength is 1.3
Explanation:
1. To find the speed of a wave you have to do the formula of speed.
Speed = Wavelength x Wave Frequency.
Speed = 1.5 * 260
= 390

The pressure of a cylinder with the following dimensions: radius 13.9 cm and height 34 cm; has a pressure of 172.9 kPa. If the pressure is reduced to 1.75 atm, what will be the volume of the gas inside the cylinder?
Answer:Experience has shown that several properties of a gas can be related to each other under certain conditions. The properties are pressure (P), volume (V), temperature (T, in kelvins), and amount of material expressed in moles (n). What we find is that a sample of gas cannot have any random values for these properties. Instead, only certain values, dictated by some simple mathematical relationships, will occur.
