What A nebula is a cloud of dust and gas loosely held together by gravity?
A nebula IS a cloud of dust and gas loosely held together by gravity.
What are two forces acting on the particles inside a nebula that effect its balance?
Two forces that act on particles inside a nebula are gravity, which pulls particles together to form new stars and solar systems, and radiation pressure, which pushes particles apart due to the energy emitted by hot stars within the nebula. These forces must be balanced for a nebula to maintain its structure and not collapse or dissipate.
Why is the force of gravity in a nebula very weak?
Gravitational force is dependent directly on the mass of the object and inversely dependent on the distance. So with the mass of the nucleus being so small, the gravitation al force is also very weak.
Moment of inertia of an helix?
The moment of inertia of a helix (coil) can be calculated using the formula for a thin rod rotated about its end axis. The moment of inertia of a helix will depend on its radius, pitch, and total length. It involves integration to account for the helical shape.
What evidence did watson and crick use to disprove linus paulings triple helix thery?
Watson and Crick used X-ray diffraction data and molecular modeling to disprove Linus Pauling's triple helix theory of DNA. Their analysis showed that the structure of DNA was a double helix, not a triple helix as proposed by Pauling. This discovery revolutionized the understanding of DNA structure and function.
What is the difference between the Helix Nebula and the Ring Nebula?
The Helix Nebula is a planetary nebula located in the constellation Aquarius, while the Ring Nebula is a planetary nebula located in the constellation Lyra. The Helix Nebula appears more like a disk or helix shape, while the Ring Nebula appears as a ring or donut shape due to its orientation.
What kind of nebula is the eye of god?
The eye of god is a Helix nebula. Close to a Planetary nebula.
How big is the helix nebula compared to earth?
The Helix Nebula is much larger than Earth. It spans about 2.5 light-years in diameter, while Earth's diameter is about 12,742 kilometers. This means the Helix Nebula is thousands of times larger than Earth.
What is the closest nebulae from Earth?
I think its the helix nebula
What are the names of the nebula?

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.
Are particles in the nebula attracted to one another because of gravity?
Yes, particles in the nebula attracted to one another by gravity?
How do gravity and pressure keep a nebula from collapsing?
Gravity pulls the particles in a nebula towards the center, trying to collapse it. However, pressure from gas and radiation within the nebula counteracts gravity, creating a balance that prevents collapse. This balance is crucial for the formation of stars from 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.
How big is the helix nebula compared to our sun?
If the Helix Nebula was an ocean, our Sun would be like a grain of sand. Nebulas are so huge that it takes light thousands of years to cross one, and light is the fastest thing we know of.
What force holds matter of nebula together?
Gravity is the force that holds matter in a nebula together. As the nebula contracts under its own gravity, the particles begin to clump together, eventually forming stars and other celestial bodies.
What force causes nebula to collapse?
Gravity is the force that causes nebulae to collapse. As particles within the nebula are pulled together by gravity, they begin to clump and form denser regions. This leads to the eventual formation of stars and planetary systems within the collapsing nebula.
