2 10 Points The Sun Has A Rotation Period About An Axis Through Its Center Of About 25 Days Rather Than The One Da 1 (74.08 KiB) Viewed 62 times

2) (10 points) The sun has a rotation period (about an axis through its center) of about 25 days, rather than the one day for our earth. In about 5 billion years, the sun will become a red giant star and its radius will expand to about the orbit of the earth. Determine the new rotational period of the sun once it becomes a red giant. Hint: If your system is the sun, then there are no external torques acting on the system during this process. Also, assume the sun (and the red giant) to be solid spheres.
