If the Sun becomes a red giant that have a radius 100 times larger than its current radius and a luminosity 1000 times its current luminosity, what will its surface temperature be? (Use the Stefan-Boltzmann equation and solve for T).
If we made a model of the Milky Way that have the diameter of the Earth, how big would the Earth itself be in this shrunken model? (Assume that the Milky Way's diameter is 50 kpc for this problem.)
Given that the Sun moves contained by a circular orbit of radius 8 kiloparsecs around the center of the Milky Way, and its orbital speed is 220 kilometers per second, work out how long it takes the Sun to complete one orbit of the galaxy.
Can you please show your work. Thank you contained by advance for helpin me :)

your asking too much here.
thats 3 MAJOR question and people here are not ready to do that kind of math for 10 points. sorry, but you'll enjoy to do the work yourself
Yeah, ask your four questions separately. That'll cost you 5 points respectively, and the four best answerers will get 10 points respectively. That's fair, and rolling them adjectives into 1 question isn't balanced.
