What happens to a nebula as it contracts?
A nebula (gas cloud) slowly contracts under the mutual gravity of all of the atoms in the cloud. As the nebula contracts, whatever initial tumbling/rotational motion is increased to conserve angular momentum (just like when a spinning figure skater brings in their arms). The nebula flattens into a disk.
What happens to the shape of a nebula as it contracts and spins faster?
As it contracts, it spins faster and faster, much like an ice skater who pulls in her arms. This effect is known as conservation of angular momentum. As a result of the spinning, the nebula flattens out to form a disk, much like a clump of dough which is spun into a pizza.
What happens when the solar nebula contracts quizlet?
What happens when a solar nebula contracts? It heats up, spins faster, flattens out. What is true about solar system densities? the denser planets lie closer to the Sun.
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.
What causes pressure inside of a nebula?
Inside the core, density and temperature increases as atomic collisions increase, causing a rise in gas pressure. Finally when gas pressure is equal to gravity, the protostar has reached equilibrium and is therefore reached a reasonably stable size.
What does the inside of a nebula look like?
The inside of a nebula would not look that much different from what we see when we look out at space. In the visible spectrum is may look like a faint haze or darkening of the stars. These images are combined to highlight the nebula. Often you can see right through them in some wavelengths of light.
What force causes particles in a nebula to condense over time?
gravity
Is Nebula bigger than 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.
Which nebula is Earth in?
the Helix Nebula

Are there 26 dimensions?
There could be an infinite number of dimensions. But as it turns out, at least for SST, 10 dimensions work for fermions and 26 dimensions work for bosons. Remember that a particle is defined by the particular vibrational pattern is has and that pattern is defined by the shape of the space in which it vibrates.
