Is a nebula held together of the outward force of gravity?
Yes, a nebula is held together by gravity. Gravity causes the gas and dust within a nebula to contract and clump together, eventually forming stars and other celestial bodies.
What keeps a protostar from collapsing?
A protostar is supported against gravitational collapse by the outward pressure generated from the heat produced by gravitational contraction. This pressure, known as radiation pressure, acts to counterbalance the force of gravity pulling the protostar inward. As the protostar continues to contract, it eventually reaches a point where nuclear fusion ignites in its core, providing an additional outward pressure that stabilizes the star against collapse.
What force opposes nuclear fusion in the sun?
The force that opposes nuclear fusion in the sun is gravity. Gravity is constantly pulling inward, trying to compress the sun's material into a smaller space. The outward pressure from nuclear fusion counteracts this force, creating a delicate balance that maintains the sun's stability.
Why would an inward opening hatch be a liability under pressure?
An inward opening hatch would be a liability under pressure because as pressure increases, it can become difficult or impossible to open the hatch due to the force acting against it. This can trap individuals inside or hinder their ability to escape in an emergency situation. Additionally, an inward opening hatch can be more prone to leaking or collapsing under high pressure conditions.
How does Hydrostatic equilibrium work?
Hydrostatic equilibrium is the balance between the inward force of gravity and the outward pressure gradient in a fluid, like in a star or planet. This equilibrium prevents further collapse or expansion by ensuring that the pressure within the fluid supports the weight of the overlying material. In stars, this balance between gravity and pressure helps maintain their stable size and shape.
Pressure from the hot particles in the sun hold it against what?
Pressure from the hot particles in the Sun counteracts the gravitational force pulling the Sun's mass inward. This balance between the outward pressure generated by nuclear fusion in the Sun’s core and the inward pull of gravity is what maintains the Sun's stability. Essentially, the immense heat and pressure created by fusion reactions create an outward force that prevents the Sun from collapsing under its own gravity.
What is the inward force that holds a star together?
Gravity, the force of attraction between all masses in the universe, is the inward force that holds a star together.
What is the inward force acting on a star?
Gravity.
What two forces are working against each other in a star?
In a star, the force of gravity is trying to collapse the star inward, while the pressure from nuclear fusion in the core creates an outward force, resisting the gravitational collapse. These two forces are balanced in a stable star, leading to a state of equilibrium.
What is the inward force of the sun on the planets?
gravity not to sure tho
What is gravitational equilibrium?
Gravitational equilibrium is the balance between the inward force of gravity and the outward force of pressure in stars. This balance allows the star to maintain its size and shape without collapsing or expanding. In gravitational equilibrium, the force of gravity pulling inward is countered by the pressure pushing outward, resulting in a stable equilibrium state.
When a star's inward gravity and outward pressure are balance the star is said to be?
Hydrostatic equilibrium occurs when compression due to gravity is balanced by a pressure gradient which creates a pressure gradient force in the opposite direction. The balance of these two forces is known as the hydrostatic balance.
As the cloud collapses the force of gravity drawing the cloud inward because?
As the cloud collapses the force of gravity drawing the cloud inward gradually becomes stronger because the strength of gravity follows an inverse square law with distance. hope that helps.
What do the outward and inward forces acting on a star have to do with it's size?
The outward force is the pressure generated by nuclear fusion in the star's core, which counteracts the inward force of gravity trying to compress the star. The balance between these forces determines the size and stability of the star. If the outward pressure exceeds the gravitational force, the star can maintain its size and stability.
Is a nebula held together of the outward force of gravity?
Yes, a nebula is held together by gravity. Gravity causes the gas and dust within a nebula to contract and clump together, eventually forming stars and other celestial bodies.
What causes the outward force in a star?
The outward force in a star is caused by the pressure generated from the energy released during nuclear fusion in its core. This pressure counteracts the force of gravity pulling inward, creating a stable equilibrium that allows the star to maintain its shape and balance.
Stars balance there inside gravity by?
The inward force of gravity is counteracted by two outward forces: gas pressure, and radiation pressure. Once the star runs out of fuel, the radiation pressure stops, the gas pressure is no longer enough to counteract gravity, and the star collapses - into a white dwarf, a neutron star, or a black hole, depending on its mass.
