[QUOTE=Lord Il Palazzo]
I may as well join in:

  1. What is the difference between a meteor and a meteorite?

  2. The word mammal derives from the name of glands which mammals use to produce what?

  3. According to the theory of relativity, what happens to an object’s mass as its speed approaches the speed of light?

  4. The sun is approximately ___ times more massive than Jupiter. (Round your answer to the nearest power of 10.)

  5. One of these things is not like the others. Which one? (And why?) Lithium, Helium, Hydrogen, Potassium

  6. A scientist has created a machine that can directly convert matter into energy with 100% efficiency. What is the energy produced by converting an object of mass M?

  7. The orbit of a planet around a star is what shape if the orbit has eccentricity=0?

  8. Place these taxonomic ranks in order from the broadest to the most narrow. Genus, Class, Kingdom, Phylum, Species, Order, Family

  9. Name the three geologic periods during which dinosaurs lived. (Order doesn’t matter.)

  10. What is the acceleration caused by gravity at sea level on the earth? (Give your answer in ft/s^2 or in m/s^2)
    [/QUOTE]

  11. A meteor is in space, a meteorite is part of a meteor that survives its decent through our atmosphere and hits the ground.

  12. Milk

  13. As an object approaches C, it’s mass increases.

  14. 700?

  15. Helium, because it is inert. I believe the others are alkaline metals and are highly reactive/corrosive?

  16. E=MC^2

  17. A Circle? (But would it still be technically an ellipse, since the orbit would have 2 foci?)

  18. Kingdom, Family, Order, Phylum, Genus, Class, Species? (ow, I’m sure that’s gonna hurt).

  19. Triassic, Jurassic, Cretaceous?

  20. isn’t it 32 ft/s^2?

I feel good about most of those… I think that puts you in the green.

  1. What is a Lagrangian point?
  2. What is Cruithne?
  3. What is a Hill sphere?
  4. What is a Dyson sphere?
  5. What is the Chandrasekhar limit?
    [/QUOTE]

  1. I believe there are 5, between 2 major gravitational bodies, and they are points between them where their respective gravities cancel each other out?

  2. Don’t know.

  3. Gah, I dunno!

  4. That’s composed of a sphere of satellites or a solid hull designed around our sun (or a star) to capture and use its energy. We start building one in the year 45,602 AD. Thanks Freeman Dyson!

  5. I know the name, but not its meaning. :frowning:

√1) A meteor is in space, a meteorite is part of a meteor that survives its decent through our atmosphere and hits the ground.

√2) Milk

√3) As an object approaches C, it’s mass increases.

X4) 700?
Note: it’s about 1000.

√5) Helium, because it is inert. I believe the others are alkaline metals and are highly reactive/corrosive?
Note: Helium is an inert nobel gas. The others are all from period one, but hydrogen isn’t considered an alkaline metal.

√6) E=MC^2

√7) A Circle? (But would it still be technically an ellipse, since the orbit would have 2 foci?)
Note: While a circle is technically an ellipse, it only has one focus. As eccentricity approaches 0, the foci move closer together until they converge to one point, the center of the now circular ellipse.

X8) Kingdom, Family, Order, Phylum, Genus, Class, Species? (ow, I’m sure that’s gonna hurt).
Note: Kindgom, Phylum, Class, Order, Family, Genus, Species.

√9) Triassic, Jurassic, Cretaceous?

√10) isn’t it 32 ft/s^2?
Note: Correct. This is also 9.8 m/s^2 for anyone interested.

  1. I think I know this: Australia.

  2. Isn’t this the locomotion of a cell?

  3. Wow. Um… thinking… Fast-twitch, Slow-twitch (?), and involuntary?! I’m guessing quadriceps, biceps, and heart respectively. (I’m sure I made a mess of that.)

  4. Causes beating?

  5. Hrmm, Speed is the over all movement of something (like the spinning of a wheel on a vehicle), and velocity is the speed of something in a certain direction of motion (how fast that vehicle is moving along a certain axis)?
    [/QUOTE]

  1. Correct! Even I was kinda iffy on this one.
  2. Nope, Chemotaxis is the method that cells use specific identifier particles to aggregate towards, so it’s not locomotion per say, but rather how cells aggregate and gather to an area.
  3. Answer was much simpler: Skeletal, Smooth, and Cardiac (you did name 2 kinds of Skeletal muscle though, but Involuntary isn’t a category). Def. a good effort.
  4. Actually it SLOWS down the beating of the heart.
  5. Correct!

    [/QUOTE]

  1. Essentially correct. Only one point is actually between the two bodies though. diagram here +1
  2. Cruithne is sometimes incorrectly said to be Earth’s second moon. It actually orbits the Sun; its orbit is near but not identical to Earth’s. -1
  3. A Hill sphere describes the maximum distance at which an orbiting body in a system may have its own satellites. Beyond this, gravitational effects from other bodies in the system make any potential satellites unstable; they will eventually be lost. -1
  4. Correct. +1
  5. The Chandrasekhar limit is the maximum nonrotating mass that can exist without eventually collapsing into a black hole or neutron star, about 1.4 solar masses. A star that is still burning can be larger than this, due to the outward energy released by fusion. -1

  2. aww, damn… I have no idea. I can’t even remember any star names around that area!

  3. I know precession makes a wide sweep, but I don’t know this either. Maybe a star from ursa minor/major, or Cassiopia? But I can’t remember any actual star names from them!

Sorry Prav!

The kind of questions I would expect my better students to actually retain over summer break (You can pick only some of them if you want, AFAI care):

  1. What’s an alpha particle?

  2. What’s the mass of one mole of Carbon-12?

  3. What’s neutral pH?

  4. What’s absolute zero in Celsius?

  5. All elements heavier than lead are ___________.

  6. What is the heaviest naturally occurring element?

  7. Name 3 indications that a chemical reaction has happened.

  1. A decayed neutron?

  2. ugh, I don’t know moles.

  3. I remember the half-way point between alkaline and acid is at 7 on the scale. Acids are higher than that, and bases are lower.

  4. Well, it’s 0º Kelvin. :smiley: I do remember that it’s like -460ºF… But I can’t remember it in Celsius! sigh I’ll take a stab. Here’s my logic:

Freezing point = 0ºC / 32ºF — Boiling Point = 100ºC / 212ºF… ergo… that’s a spread of 100 degrees for C, and 180º for F.

That’s a 1:1.8 ratio.

So, -460 ÷ 1.8 = -255.6ºC?

If I get that right, I’ll eat my hat.
5) Transition Metals?

  1. Uranium?

  2. Change in temperature; change in volume; change in color? (I’ll bet that’s not what you were looking for :sobs: )

  1. Increases lactation?

  2. Pff! Not so good with the chemical formulas. Although, I know there’s gotta be carbon in there, somewheres.

  3. Endo = Under; Symbiotic = 2 life forms living off each other in harmony. Put them together and you have: A Theory that there are life forms living beneath our skin. I got nuthin’.

  4. I believe this is synthetic adrenalin. I think it reduces the inflammation caused by an allergic reaction also opening the vascular system? Yeek, I know that’s close.

  5. Is that the one where you shit yourself to death?! All I know is it’s a bacterial infection in the intestines. (dehydration?) Will that do?!

  1. From what I know, a stroke is a blood vessel that blows out, and bleeds into the brain. An aneurysm is brought on by a blockage in the blood flow to the brain, usually from a blood clot, IIRC.

  2. Eeesh. I know it’s a popular idea in movies that that’s true, but I’m gonna go with False. I think it’s really more of a breakdown in mental functions such as determining reality and the like.

  3. I do not know. So, fill a feller in…

  4. Hunh. God, I think I oughtta know… But I don’t.

  9. I really had no idea that there was any dogma associated with the science. Umm… That biology is strictly only the study of life? Things like viruses might not be considered life? Gah. I dunno.

  10. Isn’t that like plankton?
