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 keeps white dwarf from collapsing under its own weight?
White dwarfs are supported against collapse by electron degeneracy pressure, a quantum mechanical effect that prevents electrons from occupying the same energy state. This pressure counteracts the force of gravity trying to compress the white dwarf further, maintaining its stability.
How can a container hold water?
A container can hold water by having a sealed or watertight structure that prevents the water from leaking or spilling out. The container's shape and material determine its ability to hold water without breaking or deforming under the weight of the water. It's important for the container to have walls and a base that can support the weight and volume of the water without collapsing.
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.
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 prevents corrosion?
Under Coating
What are the statistics for dwarfism?
A dwarf is a person under 4'10".
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 .)
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.
Why is the trachea so constructed?
It needs to be able to function under the pressure of breathing and head movement without collapsing.
