Week 3 & 4: Atoms and Proof Earth moves

Who was it who proposed that mass bends space and gravity is a consequence of bent space. He predicted the bending of starlight?

Who was it who's equations predicted that the Universe can not exist?

One astronomical unit (AU) is the distance from?

One Parsec is?

One MegaParsec is?

300,000 km/s x 24 x 60 x 60 x 365.25 = 1 x 10^13 km (10 trillion km)

1 x 10^-10 meters and is the size of one hydrogen atom.

The "____" and the "____" are the two particles that give rise to mass and electric charge.

The "____" is a particle that is made of one proton plus on electron.

Who discovered that protons clump together in the center of atoms. The diameter of the nucleus is about 10^-15 meters.

What is it that explains how protons stay together in the nucleus of atoms?

Which force is 10^38x stronger than gravity?

What is the proper order of forces from decreasing strength?

What are located in orbuts near the nucleus of an atom but very rarely in the nucleus?

What are mainly filled with empty space?

What are atoms held togther by sharing electron orbits (electron-magnetic force)?

What is a weather system moving south to north in the northern heisphere is deflected to the East because as it moves north it is moving sideways faster than the ground underneath?

What is caused by the revolution of the earth about the sun. It makes starlight appear to come from a different direction than the actual star position?

What was first observed in 1838 and is caused by the motion of the earth around the sun?

The nearest star has a parralax of?

What explains the reddening of a light emitting object as it rushs away from you?

If the Earth is in motion with the Sun, on average it must be going:

The Earth's rotation rate is?

The order of planets:
