0. As you know if you've been following this series, I have
previously posted the last set of questions that my team wrote
for the league (in January-April 2007) and am now completing
the season that we did before that (in January-April 2003).
As I have also mentioned, the season that we did before *that*
was in January-April 1998 (jointly with another team), and I do
have the full set of those, but only on paper.

So I could post the questions from 1998, but I'd have to retype
them (which is no trouble to speak of) and scan all the handouts
in (which is not much trouble). I'm willing to do that and
continue posting the questions from 1998 on the same basis as
with these games from 2003 -- if people want to play. I would
wait until the New Year and probably start posting a few days
into January.

But only if there is interest. If not, Round 10 of this game,
later this week, will be the last round of Old Questions From The
Canadian Inquisition that I'll be posting.

So the question is, *would* you like me to do the questions
from 1998? And if I do, should I give continue to include the
Canadiana rounds each time? (I figure I should -- there are
usually a few answers that foreigners can guess, and they serve
to fill out the typical pattern of two rounds per posting set.
But if the consensus is otherwise, then I won't.)

Yes, please keep posting them.

Final, Round 9: Science

* Kinematics

1. What is the term for a force applied to an object in such a
manner that it moves in a circle? (For example, the Sun's
gravity as applied to the Earth.)
centripetal
2. Several objects are sliding toward each other on a frictionless
surface; you know all the masses and velocities. They collide
and stick together in a single lump. You can calculate the
resulting velocity of this lump by using the fact that what
quantity is always conserved?
momentum
3. (Please decipher the rot13 only after you are finished with
#2.) What is the term for a collision where kinetic energy is
conserved as well as momentum?
elastic

* Calculus

Please refer to the handout ***, and relax, you aren't going to be
asked to evaluate any of the expressions:
http://torquiz.freeshell.org/2003-1/questions/Final/math.pdf

4. Which expression contains an indefinite integral?
8
5. Which expression contains a second derivative?
2
6. Which expression contains a partial derivative?
1

* Legumes

Please refer to <http://www.eskimo.com/~scs/msb/legumes.png>.

(At the original game, actual legumes were passed out. I don't have
a list of what the decoy ones were, so I've assembled this image by
selecting the three desired images and 12 others picked arbitrarily,
all from a commercial site, <http://www.purcellmountainfarms.com>.)

7. Identify the adzuki beans.
5,9
8. Identify the cow beans.
8,3
9. Identify the pigeon peas.
11,2

* Recyclable plastics

Recyclable plastics are commonly numbered 1 through 6 for sorting
purposes. #7 (called "Other") you might as well plant flowers in.

10. Plastic #3 is commonly used for plastic pipes, outdoor furniture,
shrink wrap, water bottles, etc. By what name is it better known?
The common abbreviation is acceptable.
PVC
11. Plastic #6 is used to manufacture CD jewel cases, plastic
cutlery, insulation, and packaging materials, among other things.
Name it. This time we want the full name, not an abbreviation,
and if you feel impelled to answer with a well-known trademark
of Dow Chemical, please resist this because we won't accept it.
Polypropylene
12. Plastics #2 and #4 are abbreviated HDPE and LDPE respectively.
Give the full name of either.
High Density Polyethylene

* Geology

13. There are three major types of volcanoes: cinder cones,
composite, and this type. All the islands of Hawaii are formed
from this type of volcano, which is created from large runny
lava flows that create a domed mountain.
caldera
14. There are two types of crust, oceanic and continental.
Continental crust is composed mostly of granite, while oceanic
crust is composed mostly of what rock?
basalt
15. What is the name of the largest volcano in the solar system?
It's extinct, and it's on Mars.
Olympus Mons
