Why does a molecular cloud flatten out as it collapses?
This flattening is a natural consequence of collisions between particles in a spinning cloud. A cloud may start with any size or shape, and different clumps of gas within the cloud may be moving in random directions at random speeds. When the cloud collapses, these different clumps collide and merge, resulting in a flattened rotating disk. Comments: Importantly, the cloud will be spinning slightly, because of random motion effects. As it collapses it will spin faster (conservation of angular momentum). You can then explain what happens it in terms of the "centrifugal effect". This effect is smallest near the axis of rotation of the cloud. So that the cloud will naturally flatten out. A more technical explanation uses the "law of conservation of angular momentum". This shows again the natural tendency to form a disk from a spinning cloud.

If you wanted to observe a molecular cloud in what wavelength of light would you most likely observe?
You would most likely observe a molecular cloud in the infrared wavelength of light. This is because molecular clouds are dense regions of gas and dust where new stars are forming, and infrared light can penetrate the dust and reveal the inner structure and temperature of the cloud.
What is the first step in building a solar nebula?
The first step in building a solar nebula involves the gravitational collapse of a molecular cloud, which is a dense region of gas and dust in space. As this cloud collapses under its own gravity, it begins to spin and flatten into a disk shape, creating the conditions necessary for the formation of stars and planetary systems. This process is influenced by factors such as turbulence, shock waves, and the presence of nearby supernovae.

As a rotating cloud collapses its rate of rotation?
increases due to conservation of angular momentum. As the cloud collapses, it spins faster to conserve angular momentum, just like a figure skater spins faster when they bring their arms closer to their body. This increased rotation can eventually lead the cloud to form a protostar at its center.
What is the role of rotation in the process of stellar birth?
Rotation plays a key role in the process of stellar birth by influencing the collapse of a molecular cloud into a protostar. As the cloud collapses, conservation of angular momentum causes it to spin faster, forming a protostellar disk. This disk is where material accumulates to fuel the growth of the protostar.

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.
The most common molecule in a molecular cloud is?
The most common molecule in a molecular cloud is molecular hydrogen (H2).
Why are stars born?
Stars form from collapsing clouds of dust and gas within regions of molecular clouds, often called stellar nurseries. As the cloud collapses its density and temperature increase until it eventually reaches the point where a start begins to form in the center of the cloud.
When a nebula collapses small regions in the cloud called?
globules
What happens to the visible radiation produced by new stars within a molecular cloud?
The visible radiation produced by new stars within a molecular cloud is absorbed and scattered by the surrounding gas and dust in the cloud. This can cause the radiation to be reddened, blocked, and scattered in different directions, making it more difficult to detect the stars visually.
What does the gravitational force in a molecular cloud depends on?
The gravitational force in a molecular cloud depends on the mass of the cloud and the distance between particles. The force is stronger when there is more mass within the cloud and when particles are closer together.

What physical law explains why a cloud heats up as it collapses?
The ideal gas law explains why a cloud heats up as it collapses. As the cloud shrinks in size, the volume decreases, causing an increase in pressure and temperature due to the conservation of energy. This process is known as adiabatic compression.
