What is the relationship between gravity and pressure in a solar nebula?
What is the relationship between gravity and pressure in a solar nebula?
The roles of gravity and pressure in the solar system is that the gravity pulls on all the particles in a nebula. Pressure is made up of collisions which cause particles to push away from each other.
How do gravity and pressure keep a nebula from collapsing?
How do gravity and pressure keep a nebula from collapsing? Outward pressure balances the inward gravitational pull and keeps the cloud from collapsing.
What would happen to a nebula if the pressure inside it was greater than the force of gravity?
When the force of gravity pulling in on the cloud is greater than the strength of internal pressure pushing out, the cloud collapses into a protostar.
How does high pressure probably affect the size of a nebula?
High pressure causes the nebula to expand, or get larger. The particles spread farther apart, and pressure decreases. However, gravity increases pressure by pulling the particles together. When the nebula is just the right size, the pressure inside it exactly balances the force of gravity.
Is Earth in a nebula?
The Earth was formed from the nebula that produced the Solar System. It is almost universally accepted that the Sun, the planets and their satellites, the asteroids, and the comets of the Oort ‘cloud’ grew from a cloud of gas and dust that contracted under its own gravity.
What force pulls the matter in a nebula together?
Gravity
What force pulls the matter together?
What creates a nebula?
The roots of the word come from Latin nebula, which means a “mist, vapor, fog, smoke, exhalation.” Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases. They either form through clouds of cold interstellar gas and dust or through the aftermath of a supernova.
What causes a nebula?
A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called “star nurseries.”
How long does a nebula last?
The time it takes for a nebula to collapse into a star and start the nuclear burning of its hydrogen into helium depends on the size of the star. For a star the size of the sun, it takes about years to collapse. For bigger stars, it is a shorter time – as low as 100,000 years for the biggest stars.
What is it like inside a nebula?
Nebulas are mostly very thin material and would count as a good vacuum on Earth. More material per cubic centimetre in the vacuum of a vacuum flask. They appear solid and often brightly coloured because they are also truly vast: often light-years across.
What is the nebula stage?
The Nebula a defused, high density cloud of predominantly hydrogen and gas that slowly starts to collapse under the force of gravity . This pressure continues to increase as the nebula gets smaller and the temperature rises, leading to the next stage of a star’s life cycle. …
Are nebulae dangerous?
Nebulae aren’t inherently dangerous, so there is no minimum safe distance. In spite of what you may have seen on Star Trek, they aren’t mysterious regions of space filled with space lightning and strange effects that make ships stop navigating. They are just big clouds of dust and gas.
How many types of nebula are there?
five types
What is the most common type of nebula?
One of the most common types of emission nebula occurs when an interstellar gas cloud dominated by neutral hydrogen atoms is ionised by nearby O and B type stars.
What is the largest Nebula?
Tarantula Nebula
What is a planetary nebula group of answer choices?
What is a planetary nebula? the expanding shell of gas that is no longer gravitationally held to the remnant of a low-mass star.
What happens during the planetary nebula stage?
Low-mass stars turn into planetary nebulae towards the end of their red giant phase. At that point the star becomes highly unstable and starts to pulsate. The outer layers are ejected by the resulting stellar winds. Planetary nebula are relatively short-lived, and last just a few tens of thousands of years.
What happens after a planetary nebula?
The star becomes a white dwarf, and the expanding gas cloud becomes invisible to us, ending the planetary nebula phase of evolution. For a typical planetary nebula, about 10,000 years passes between its formation and recombination of the resulting plasma.
What’s the definition of a nebula?
Definition: A nebula is a formation in space which is constituted mostly of helium, dust, and other gases in various concentrations.
What’s another word for nebula?

Is a nebula bigger than a galaxy?
Simply put, the main difference between galaxies and nebulae are an extreme difference in size, as well as their basic structure. A nebula is a cloud of dust and gas, usually tens to hundreds of light years across. A galaxy is much larger — usually thousands to hundreds of thousands of light years across.
What is an example of a nebula?
Planetary nebulae are formed when a star dies, and create dramatic formations of radiating cosmic gas. Some great examples of planetary nebulae in the night sky include the Ring Nebula, the Dumbbell Nebula, and the Helix Nebula. Planetary Nebulae involves a low-mass star entering the final stage of its life.
What gigantic star is responsible for the characteristics of this nebula?
Gamma Cassiopeiae
How many stars can a nebula produce?
700 stars
How many galaxies are there?
XDF (2012) view: Each light speck is a galaxy, some of which are as old as 13.2 billion years – the observable universe is estimated to contain 200 billion to two trillion galaxies.
