1
Saturn's balls had spectral lines that were what compared to the reference line?
  • Slanted
  • Vertical
  • Horizontal
  • Dude, it's a trick question
2
The more slanted that Saturn's lines are means what?
  • Saturn is rotating slower
  • Saturn is rotating faster
  • They are an example of the Doppler Shift
  • There is more hydrogen near the planet
3
To calculate what we use the fact that 'it' is directly proportional to the change in the wavelength of light for a given spectral line?
  • Doppler's Shift
  • Ring Velocity
  • The Speed of Rotation (of Saturn)
  • Universial Gravitational Constant G
4
Without spectral lines to show us the change in colour, we could not measure the speed of rotation using the:
  • The Speed of Rotation (of Saturn)
  • Ring Velocity
  • Universal Gravitational Constant G
  • Doppler Shift
5
The lines of Saturn are slanted because:
  • Part of the planet is rotating away from us, and part is rotating toward us.
  • The Universal Gravitational Constant G is pulling on Saturn
  • The planet is moving one way while the rings move another
  • The rings of the planet are rotating faster than the planet
6
The spectral lines of Saturn's rings are slanted in which direction in relation to Saturn's disk?
  • Same, you silly goose
  • Opposite
  • Horizontal, but still the same
  • Horisontal, but a little faster
7
We conclude that unlike Saturn's disks, the farther a ring segment is from Saturn:
  • The faster it is rotating
  • A sand storm is going to occur on Saturn
  • The slower it is rotating
  • The more gravity is pulling on it
8
The spectral lines of Saturn's rings are slanted in the opposite direction to Saturn's disk. This is consistent with:
  • Newton's Law of Gravity
  • The Doppler Effect
  • The Universal Gravitational Constant G
  • Kepler's Law of Planetary Motion
9
We measured the mass of Saturn by observing the ring "____" and its distance from Saturn.
  • Velocity
  • Gravity
  • Wavelength Shift
  • Newtons
10

  • 120,000 KM
  • 256,00 KM
  • 180,000 KM
  • 476,000 KM
11
How big is the diameter of the inner ring of Saturn?
  • 256,000 KM
  • 120,000 KM
  • 180,000 KM
  • 476,000 KM
12
What is Saturn's diameter?
  • 476,000 KM
  • 180,000 KM
  • 256,000 KM
  • 120,000 KM
13
Compared to Earth, how much bigger is Saturn's outer ring?
  • 20x
  • 10x
  • 15x
  • It's actually smaller than Earth
14
Compared to Earth, how much bigger is Saturn?
  • It's actually smaller than Earth
  • 10x
  • 20x
  • 15x
15
Which equation do we use to calculate the velocity of Saturn?
  • F = Gm1m2^2
  • 3.6 x 10^19
  • Δλ/λ=Δv/c
  • 6 x 10^24
16
For two equal masses of one kilogram, seperated by one kilometer, the force of gravity felt by the two masses is?
  • 6 x 10^24
  • Δλ/λ=Δv/c
  • 2 x 10^30
  • G = 6.67 x 10^-20
17
One Newton is about how much?
  • 1/5th of a pound
  • 1 pound
  • 1/2 of a pound
  • 3/4 of a pound
18
The mass of the Sun is:
  • 6 x 10^24
  • 2 x 10^30
  • 1.5 x 10^8
  • 3.6 x 10^19
19
The mass of the Earth is:
  • 3.6 x 10^19
  • 1.5 x 10^8
  • 6 x 10^24
  • 2 x 10^30
20

  • 2 x 10^30
  • 6 x 10^24
  • 3.6 x 10^19

21
Using which equation,can we find the force of the Sun on the Earth?
  • F = Gm1m2^2
  • Δλ/λ=Δv/c
  • 1.5 x 10^8
  • 3.6 x 10^19
22
The force of the Sun on the Earth is:
  • 1.5 x 10^8
  • 3.6 x 10^19
  • 6 x 10^24
  • 2 x 10^30
23
The force of the Sun on you is about:
  • 0.06 grams
  • 1/6th of a pound
  • 1/5th of a pound
  • 0.05 grams
