- 100,000 x 10,000 = 1,000,000,000 is represented how in scientific
notation?
- 100
^{3}x 10^{3}= 10^{9} - 1000
^{2}x 1000^{1}= 1000^{6} - 10
^{5}x 10^{4}= 10^{9} - 1
^{5}x 1^{4}= 1^{9}

- 100
- To multiply two numbers in scientific notation:
- Add Exponents
- Subtract the bottom exponent from the top
- Subtract the top exponent from the bottom
- Multiply the exponents
- Divide the top exponent by the bottom

- To divide two numbers in scientific notation:
- Add Exponents
- Subtract the bottom exponent from the top
- Subtract the top exponent from the bottom
- Multiply the exponents
- Divide the top exponent by the bottom

- To add or subtract numbers in scientific notation:
- Add Exponents
- Subtract the bottom exponent from the top
- Subtract the top exponent from the bottom
- Multiply the exponents
- Write the numbers out and add or subtract

- Negative Exponents mean
- Numbers less than 1
- Numbers less than 0
- Square roots
- Numbers larger than infinity

- Anything to the zero power equals
- Itself
- One
- Zero
- 1 over the number

- A light year is
- The distance light travels in a year
- The time it takes light to cross the galaxy
- The time it takes light to cross the earth's orbit
- Everything you want in a regular year and less

- 32 F =
- 0 C (Water freezes)
- 100 C (water boils)
- 32 C (Scales Equal)
- 98.6 C (Body temperature)

- 212 F =
- 0 C (Water freezes)
- 100 C (water boils)
- 212 C (Scales Equal)
- 98.6 C (Body temperature)

- -40 F =
- 0 C (Water freezes)
- 100 C (water boils)
- -40 C (Scales Equal)
- 98.6 C (Body temperature)

- One C degree equals
- 100 F degrees
- 1.8 F degrees
- 0.5 F degrees
- 0.1 F degrees

- Absolute zero is where
- My grade will be after this exam
- All atomic motion stops
- The Celsius and Fahrenheit scales are equal
- Water freezes

- The Kelvin Scale differs from the Celsius scale how?
- Celsius starts at Absolute Zero
- Kelvin starts at Absolute Zero
- Kelvin degrees = 1.8 Celsius degrees
- It runs in the opposite direction

- To convert Kelvin to Celsius
- Add 273
- Subtract 273
- Multiply by 5/9 and add 32
- Multiply by 9/5 and subtract 32

- Telescopes that use lenses to create images are called
- Refractors
- Reflectors
- Diffractors
- Dementors

- Telescopes that use mirrors to create images are called
- Refractors
- Reflectors
- Diffractors
- Dementors

- The largest telescopes today are all
- Refractors
- Reflectors
- Diffractors
- Dementors

- Why are the largest telescopes reflectors?
- Mirrors get cheaper the larger they are
- It is very hard to make optically perfect large lenses
- Reflectors are easier to mount
- Reflectors are easier to repair

- Telescopes that use both lenses and mirrors to create
images are called
- Refracto-reflectors
- Mirror-Lens telescopes
- Compound telescopes
- Newtonian telescopes

- The biggest virtue of compound telescopes is
- They are cheaper than other kinds
- They are more powerful
- They can be much more compact than other telescope designs
- They are easier to construct

- To astronomers, the single most important function of a telescope is to
- Collect light
- Magnify the image
- Resolve fine detail
- Create spectacular photographs

- Telescope mounts that rotate horizontally and vertically are called
- Altazimuth
- Equatorial
- Cantilever
- Biaxial

- Telescope mounts with an axis aligned parallel to the earth's axis are
called
- Altazimuth
- Equatorial
- Cantilever
- Biaxial

- Why are equatorial mounts built that way?
- It's easier
- It supports the telescope better
- It allows the telescope to follow objects with a single movement
- It uses less materials

- How often do astronomers observe through large telescopes visually?
- Most of the time
- When photography isn't sensitive enough
- About an equal mix of visual and photographic observation
- Hardly ever
