What two events can upset the balance between gravity and pressure in a nebula?
Two events that can upset the balance between gravity and pressure in a nebula are a supernova explosion or the collision of two nebulae. A supernova explosion releases an enormous amount of energy and can disrupt the delicate equilibrium between gravity and pressure. The collision of two nebulae can also disturb the balance by introducing additional gravitational forces and increasing the overall pressure within the system.
Stars begin as huge clouds of dust and gas that contract and heat up to the point of?
fusion begins in their cores, producing energy and creating a balance between the force of gravity pulling inward and the internal pressure pushing outward. This balance allows stars to shine brightly and sustain their structure for millions to billions of years.
What kind of pressure supports a white dwarf?
A white dwarf is supported by electron degeneracy pressure, which is the repulsion between closely-packed electrons that prevents further gravitational collapse. This pressure is a result of the Pauli exclusion principle, which states that no two electrons can occupy the same quantum state.
Why do stars expand and contract in size?
Stars expand and contract in size due to the balance between gravitational forces pulling inwards and internal pressures pushing outwards. When nuclear fusion in the core of a star produces energy, it creates an outward pressure that can cause the star to expand. As the star's core exhausts its fuel, the outward pressure decreases, causing the star to contract under its own gravity.
How do stars keep their spherical shape?
Stars maintain their spherical shape due to the balance between internal pressure pushing outward from nuclear fusion reactions in the core and gravity pulling inward. This equilibrium creates a stable equilibrium that keeps the star from collapsing under its own gravity and helps to maintain its rounded form.
What is inner clits?
supports balance between truss members
What is the balance between the internal and external environment?
walls
What is internal equilibrium?
The internal equilibrium is a balance condition between internal forces and the commulative integrated stresses.
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.
What can upset the balance between gravity and pressure in a nebular?
You used the term nebular. I take it you mean a galaxy. There would not be a balance between gravity and pressure. There would be a balance between gravity and centrifugal force.
What is the relationship between the internal energy of an ideal gas and its temperature and pressure?
The internal energy of an ideal gas is directly proportional to its temperature and is independent of its pressure.
What two events can upset the balance between gravity and pressure a nebula?
The balance between gravity and pressure can be upset if two nebulas collide. It can also be upset if a nearby star explodes.

Two events that can upset the balance between gravity and pressure in a nebula are a supernova explosion or the collision of two nebulae. A supernova explosion releases an enormous amount of energy and can disrupt the delicate equilibrium between gravity and pressure. The collision of two nebulae can also disturb the balance by introducing additional gravitational forces and increasing the overall pressure within the system.
True or false as nuclear fuel runs out a star's internal structure and its mechanism for producing pressure change to counteract gravity?
True. As a star runs out of nuclear fuel in its core, the balance between pressure and gravity is upset. This can lead to the core collapsing and triggering other nuclear reactions in different regions of the star, which in turn can cause the star to undergo changes in its internal structure and mechanisms for producing pressure.
What is the relationship between temperature, pressure, and volume in determining the total internal energy of a gas?
The relationship between temperature, pressure, and volume in determining the total internal energy of a gas is described by the ideal gas law. This law states that the total internal energy of a gas is directly proportional to its temperature and is also affected by its pressure and volume. As temperature increases, the internal energy of the gas also increases. Additionally, changes in pressure and volume can affect the internal energy of the gas through their impact on the gas's temperature.
Why are we not crushed by the weight of the atmosphere on our shoulders?
We are not crushed by the weight of the atmosphere on our shoulders because our bodies are designed to withstand the pressure exerted by the air around us. The human body has evolved to maintain a balance between the internal and external pressures, allowing us to function normally despite the atmospheric pressure.
