Due to too much of X in the body,tissues swell. So excess X outside thecells draws sodium from within the cellsout into the serum in an attempt to re-establish the necessary concentration,and sodium concentration drops - a
condition known as hyponatremia. Bothelectrolytes and X move across the cellmembrane in an effort to balanceconcentration.
Theoretically, cells could swell to thepoint of bursting and this puts pressure
on the brain and nerves, which can

X died on 24 October 1601 in Prague, elevendays after suddenly becoming very ill during abanquet.
For hundreds of years, the general belief wasthat he had strained his bladder. It had been
said that to leave the banquet before itconcluded would be the height of bad manners,and so he remained, and that his bladder,stretched to its limit, developed an infection
which later killed him. This theory wassupported by Kepler's first-hand account.
Recent investigations have suggested that X

2. Impatience - The anger you feel when the computer isbeing lazy. This makes you write programs that don't justreact to your needs, but actually anticipate them. Or atleast pretend to. Hence, the second great virtue of a

A professor of physics is going ice skating for the first time. Hehas gotten himself into the middle of an ice rink and cannot figure
out how to make the skates work. Every motion he makes simply
8/14/2019 Sci-Tech 09 Finals
151/164
slips on the ice and leaves him in the same place he started. He
decides that he can get off the ice by throwing his gloves in theopposite direction.
(a) Suppose he has a mass M and his gloves have a mass m. If
he throws them as hard as he can away from him, and they leave
his hand with a velocity v. Explain whether or not he will move. If
he does move, calculate his velocity, V.
(b) Discuss his motion from the point of view of the forces acting
on him.
(c) If the ice rink is 10 m in diameter and the skater starts in the
center, estimate how long it will take him to reach the edge,
assuming there is no friction at all
The orbiting Hubble telescope was
recently repaired by a crew of

astronauts from the Space Shuttle
Endeavor. The Hubble is in a
circular orbit 600 km above the
surface of the earth. For half of the
Hubble's orbital period it is in
sunlight and for half it is in the
darkness of the earth's shadow. As
a results of the change in fit of thevarious parts of the Hubble due to
heating and cooling of the
telescope, the astronauts could
only work on certain repairs while
the Hubble was in darkness.
Estimate how much time theastronauts had to work on these
repairs before having to stop "for a
sun-break".

approximately 2 million
books fell off the
shelves at the Stanford
University library. If you
were the library
administrator andwanted to hire enough
part-time student labor
to put the books back
on the shelves in orderin 2 weeks, how many
students would you
have to hire?
The density of water is just
The bosom of the atmosphere
8/14/2019 Sci-Tech 09 Finals
154/164
about 1000 kg/m 3 . The
density of air is just about1000 times less. From
your knowledge of the air
pressure at ground level,
estimate the height of the
atmosphere. As asimplifying assumption,
take the atmosphere to be
of uniform density up to
some height after whichthe density rapidly falls to
zero.
The Drake equation states that:
N = R* x fp x ne x f x fi x fc x L

N R x fp x ne x f x fix fcx L
where:N= No of civilizations in our galaxy with which
communication might be possible;
R* = average rate of star formation in our galaxy
fp = fraction of those stars that have planets
ne = average number of planets that can
potentially support life per star that has planetsf = fraction of the above that actually go on to
develop life at some point
fi= fraction of the above that actually go on to
develop intelligent life
fc= fraction of civilizations that develop a
technology that releases detectable signs oftheir existence into space
L = length of time such civilizations release
detectable signals into space.
