Use the diagram to answer the question.
The life trajectory of a stellar nebula is shown. The stellar nebula, a purple gas ball turns into an average star, depicted as a yellow circle, within 500 million years. The average star turns into a red giant, depicted as a medium sized red circle, within 10000 million years. The red giant turns into a planetary nebula, a bright star surrounded by green and blue gases, within 1000 million years. And the planetary nebula gradually cools into a white dwarf, depicted as a small white circle. The stellar nebula can also turn into a massive star, depicted as a medium blue circle, within 0.1 million years. The massive star turns into a red supergiant, depicted as a large orange circle, within 15 million years. The red supergiant turns into a supernova, a bright white star, within 1 million years. The supernova can either turn into a neutron star, depicted as a yellow sphere with white rays coming out of its sides, or a black hole, a small black circle surrounded by purple rays.
What determines whether a star will end its life cycle as a black hole or neutron star or as a white dwarf?

The determining factor for whether a star will end its life cycle as a black hole, neutron star, or white dwarf is its mass.
im not the same person as the person who made this thread
Apologies for the confusion. In the context of stellar evolution, the mass of a star is indeed the determining factor for its fate. Higher-mass stars have enough mass to undergo a supernova explosion and potentially form a black hole, while lower-mass stars end their lives as white dwarfs. The mass range for the formation of a neutron star is typically between 1.4 to 3 times the mass of our Sun. Therefore, the mass of the star is the correct response in this case.

How does spectroscopy provide evidence for the Big Bang theory?(1 point)
Responses
The intensities of peaks show that galaxies are moving away from each other.
The intensities of peaks show that galaxies are moving away from each other.
The intensities of peaks show that galaxies are moving toward each other.
The intensities of peaks show that galaxies are moving toward each other.
The red shift shows that galaxies are moving toward each other.
The red shift shows that galaxies are moving toward each other.
The red shift shows that galaxies are moving away from each other.
The correct answer is:
The red shift shows that galaxies are moving away from each other.
Spectroscopy allows astronomers to study the light emitted by galaxies. By analyzing the spectrum of light from distant galaxies, they observed that the light was shifted towards the red end of the spectrum. This redshift indicates that galaxies are moving away from each other, providing evidence for the expansion of the universe and supporting the Big Bang theory.
I dont care. I have a test for you. Don't answer any of the questions under this thread. They're all me. If you fail, I hate you.
I apologize if there has been any misunderstanding or if I have not met your expectations. As an AI language model, I strive to assist and provide accurate information to the best of my abilities. If there is anything specific you would like assistance with or any questions you have, please let me know and I'll be happy to help.
