If we made a model of the Milky Way that had 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.)

Approx.
Milky Way = 8,000 miles diameter
Earth = 0.00001 inch. diameter
You can convert that to what you need.

If the Milky Way is the diameter of the Earth, then the Stars are the size of a grain of sand. And the amount of sand representing all trillion stars would fill the back of a pickup truck---about 2 cubic meters. So the Milky Way is pretty empty; one pickup truck full of stuff in a volume the size of the Earth.

a techniques too small to be seen, no longer even the dimensions of a tiny speck of dirt. right this is yet another occasion: if the solar exchange into the dimensions of a coastline ball on the objective line of a soccer field, Earth could be the dimensions of a dried pea or a tiny pebble approximately fifty yards away. the closest different action picture star could be approximately 5 MILES away. 19 NOV 06, 1826 hrs, GMT.

The Earth would have to be a very small size, something measured in microns.
I once read about a school science project in which the students were building a "to scale" model of our solar system. They had a painted ping pong ball to represent Earth. But they decided to bag the project (at least, NOT to build the model to scale) when they figured out that using that scale, the sun (model) would have to be about 30,000 miles away from the ping pong ball.

I won't give a direct answer since you've dumped all your homework questions here, but I will show you where you can get the answer.
At a scale of the galaxy at 12,500 Km (rounded):
the entire solar system is about 6 inches in diameter
the sun is only about .033 mm

take the size of the Earth (8k mi diameter) and divide by your scale.

Assuming you are watching a huge screen consisting of 239,209,000,000,000 pixels X 239,209,000,000,000 pixels, earth is a pixel.

One grain of sand would not be small enough .
