Why prevents stars collapsing under the force of their own gravity?
The pressure of the fusing gasses
What keeps the sun from not falling?
The sun's immense gravitational pull created by its mass keeps it from falling. The gravitational force pulls the sun's gases and radiation inward, creating a balance with the outward pressure caused by nuclear fusion reactions in its core. This balance keeps the sun stable and prevents it from collapsing under its own weight.
What two forces stabilize a nebula?
Gravitational force pulls gas and dust particles together to form a nebula, while the outward pressure from gas particles pushing against each other (thermal pressure) prevents the nebula from collapsing under gravity. These two forces work together to stabilize a nebula.
What works with pressure to keep a nebula from collapsing?
The pressure caused by the thermal energy of the gas within the nebula pushes outward in all directions, preventing the nebula from collapsing under its own gravity. This pressure acts to counterbalance the force of gravity, maintaining the nebula's size and structure.
Which process is required to allow a gravitationally-collapsing gas cloud to continue to collapse?
The process required to allow a gravitationally-collapsing gas cloud to continue collapsing is radiative cooling. Radiative cooling removes thermal energy from the gas cloud, facilitating further collapse under the influence of gravity.
What prevents galaxies from collapsing under their own weight?
Their rotation.
Why prevents stars collapsing under the force of their own gravity?
The pressure of the fusing gasses
What is the purpose of the bridge pillars in supporting the structure of a bridge?
The purpose of bridge pillars is to provide support and distribute the weight of the bridge evenly, helping to prevent the bridge from collapsing under its own weight or the weight of vehicles passing over it.
What keeps white dwarf from collapsing under its own weight?
A white dwarf star, as well as any other stable variety of star,is held together by the pressure popularly known as "gravity".In the opposite direction, white dwarf stars are kept from collapsing completely by degeneracy pressure. Specifically, for white dwarf stars, it's electron degeneracy pressure, which arises from the fact that electrons are fermions and cannot all occupy the same energy state. For higher mass stars, the force of gravity is able to overcome this and push all the electrons into the ground state, and the star is supported by a different kind of degeneracy ... neutron degeneracy, which is the same thing but with neutrons ... and you get a neutron star. At even higher masses, even that isn't sufficient and the star collapses all the way into a black hole.
How can a container hold water?
A container is able to hold water because the container's atoms are bonded closer together than each water molecule's total size. This prevents the water molecules from sliding out between the container's atoms, thereby holding the water inside.
Why does the pyramid get narrower as it gets higher?
The pyramid gets narrower as it gets higher because each layer is built on top of the previous layer, with each layer having a smaller surface area than the one below it. This design helps distribute the weight of the pyramid and prevents it from collapsing under its own weight. Additionally, the narrowing shape helps to channel and distribute forces downward, making the structure more stable.
What keeps the sun from not falling?
The sun's immense gravitational pull created by its mass keeps it from falling. The gravitational force pulls the sun's gases and radiation inward, creating a balance with the outward pressure caused by nuclear fusion reactions in its core. This balance keeps the sun stable and prevents it from collapsing under its own weight.

What are the statistics for dwarfism?
A dwarf is a person under 4'10".
How do bridges work to support the weight of vehicles and pedestrians?
Bridges work by distributing the weight of vehicles and pedestrians across their structure, using a combination of materials like steel and concrete to provide strength and support. The design of the bridge, including its arches, beams, and cables, helps to evenly distribute the load and prevent the structure from collapsing under the weight.
How much should a 9 month old dwarf rabbit weigh?
On average, a 9-month-old dwarf rabbit should weigh between 2-4 pounds depending on the specific breed. It's important to monitor their weight regularly to ensure they are healthy and not under or overweight.
Why are caterpillar tracks used in battle tanks instead of tires?
Battle tanks use caterpillar tracks to spread their heavy weight on soft ground. this prevents the sinking of land under the weight of the tank . ( as more the surface area less the pressure .)
