What two factors cause a nebula to develop into a star?
The two main factors that cause a nebula to develop into a star are gravity and heat. Gravity pulls the gas and dust in the nebula together, causing it to collapse under its own gravity. As the collapse continues, the temperature and pressure in the core of the collapsing nebula increase, eventually reaching a point where nuclear fusion ignites, and a star is born.
What are stars in the sky held together by?
Stars in the sky are held together by gravity. Gravity is the force that pulls all the mass of a star together, preventing it from expanding outward. It is this balance of internal pressure from nuclear reactions and gravitational forces that keeps a star stable.
What holds the star together?
Stars are held together by their own gravity, which is the result of the balance between the force of gravity pulling matter inward and the pressure created by nuclear fusion reactions in the star's core pushing outward. This equilibrium allows the star to remain stable and maintain its size and shape.
Two main forces in a star?
The two main forces in a star are gravity and nuclear fusion. Gravity pulls matter inward, compressing it and creating the high pressure and temperature needed for nuclear fusion to occur. Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.
How does gravity affect our lives?
Without gravity we would HAVE NO LIVES. For instance, gravity keeps our Earth together; and gravity is an important component in making the Sun produce energy via nuclear fusion.
Which of these develop when gravity pulls gas and dust together with enough pressure to ignite nuclear fission?
The list of choices posted with the question doesn't include anything that fits that description. It sounds something like a "star", but in a star, it would be "fusion", not "fission".

Inside a star the force of gravity is balanced by?
If the force of gravity crushing a star in weren't balanced, it would collapse. The outward-pushing force counteracting gravity is the energy produced in nuclear fusion, when the heat and pressure inside of stars smashes atoms together.

Stars in the sky are held together by gravity. Gravity is the force that pulls all the mass of a star together, preventing it from expanding outward. It is this balance of internal pressure from nuclear reactions and gravitational forces that keeps a star stable.
Stars are born when gravity pulls gas and dust together with enough pressure to ignite nuclear fusion true or false?
True.
What Inside a star the force of gravity is balanced by the?
Inside a star, the force of gravity is balanced by the pressure generated from nuclear fusion reactions occurring in the star's core. These nuclear reactions create an outward pressure that counteracts the force of gravity trying to collapse the star. This delicate balance between gravity and pressure determines the size, temperature, and lifespan of a star.
What holds the star together?
Stars are held together by their own gravity, which is the result of the balance between the force of gravity pulling matter inward and the pressure created by nuclear fusion reactions in the star's core pushing outward. This equilibrium allows the star to remain stable and maintain its size and shape.
Why is the massive stars is the hottest star?
More mass means more gravity, therefore the mass gets packed closer together, causing more pressure. This facilitates nuclear reactions.
Two main forces in a star?
The two main forces in a star are gravity and nuclear fusion. Gravity pulls matter inward, compressing it and creating the high pressure and temperature needed for nuclear fusion to occur. Nuclear fusion releases energy as light and heat, which counteracts the force of gravity trying to collapse the star.
If we compare the force of gravity to strong nuclear force we could conclude that?
the strong nuclear force is much stronger than the force of gravity. Gravity is the weakest of the four fundamental forces, while the strong nuclear force holds atomic nuclei together and is much stronger than gravity on the atomic scale.
How do gravity temperature and pressure impact and affect nuclear fusion?
Gravity plays a crucial role in nuclear fusion by compressing and heating the stellar core to the high temperatures and pressures needed for fusion to occur. Higher temperatures and pressures increase the likelihood of atomic nuclei overcoming their mutual repulsion and fusing together. These conditions are found in the cores of stars, where gravity provides the necessary confinement and energy to sustain nuclear fusion reactions.
Did gravity pulled the atoms together to form heavier elements?
Yes, gravity plays a role in pulling atoms together in stars to form heavier elements through nuclear fusion. In the intense pressure and temperature conditions of a star's core, lighter elements like hydrogen fuse together to form heavier elements like helium, carbon, and oxygen.
