What conservation law might be useful? (You'll need to make some assumption about the way it collapses, e.g. that every part of it is it one hundredth of its previous radius.)physics123456 said:Homework Statement
the sun collapses to the size of the Earth (approximately 1/100 the original diameter), The current average rotation of the sun is approximately 30 days.
Homework Equations
what would be the new rotational period (time to spin once)?
The Attempt at a Solution
I know that in 30 days, the sun has to travel a distance of 2pi. But I don't understand how that would change if the sun had a smaller diameter...that's where I am confused.
A collapsing sun refers to the process by which a star, specifically a sun-like star, runs out of fuel and begins to collapse under its own gravitational force.
A sun collapses when it has exhausted all of its hydrogen fuel, which is the main source of energy that keeps it stable and prevents it from collapsing. As the fuel runs out, the sun's core starts to shrink, causing the outer layers to collapse inwards.
The average rotation of a collapsing sun can vary depending on its size and composition. However, as the star collapses, it will rotate faster due to the conservation of angular momentum.
If our sun were to collapse, it would have a significant impact on Earth and all other planets in the solar system. The collapse could lead to changes in the sun's radiation and magnetic fields, potentially affecting our climate and weather patterns.
Yes, a collapsing sun can potentially become a black hole if it is massive enough. When a star's core collapses, it can form a singularity, a point of infinite density, which is the defining characteristic of a black hole.
