Question

according to the nebular theory, what happened to the solar nebula after it collapsed? a collision with another nebula caused it to explode into a cloud of dust it spun faster and faster, eventually flattening into a disk. it got swept up by a cosmic storm and broke into many pieces fusion inside the nebula heated it up, causing it to expand again.

Explanation:

According to the nebular theory, when the solar nebula collapsed, conservation of angular momentum caused it to spin faster. As it spun faster, it flattened into a disk - shaped structure. This is a key part of the nebular theory's description of the formation of the solar system. Option A is incorrect as there is no such collision described in the nebular theory. Option C is not in line with the nebular theory's mechanism. Option D is also not the correct process described in the nebular theory for what happens after the initial collapse.

Answer:

B. It spun faster and faster, eventually flattening into a disk.
