Science & Mathematics - 21 August 2007

Got this in my e-mail.

Insha'Allah I'll catch it.

Two moons on 27th August 2007*
*27th August; the day the Whole World is waiting for Planet Mars will be the brightest in the night sky starting August.
It will look as large as the full moon to the naked eye. This will
cultivateon Aug. 27 when Mars comes within 34.65 Million miles of earth. Be sure to watch the sky on Aug. 27 12:30am. It will look like the earth has 2 moons. The next time Mars may come this close is in 2287.

Seriously, do your own little fire
experiment at home.

Make a little steel bridge or a steel
structure, and overload it so much with
bricks or dead weights, to the point
where it is just about to give way and
completely collapse... Go on... like this:

Use a 2 or 3 mm thick steel bar or flat,
you can buy this from any hardware
store. Hold it up at both ends with bricks
at both ends like the picture below:

...........BBBB
...........BBBB
__________________
BB.........fire........BB
BB.........fire........BB

(B = Brick, ignore the dots)

The steel bridge is indicated by ______

Now use steel or aluminium baking tray
underneath the bridge, filled with jet
fuel, or kerosene, and light it up with a
burning newspaper.

Burn it for as long as you like in open
air, and see if your steel bridge will
collapse due to being weakened by
exposure to air fire.

Seriously, try this experiment at home!

Use as much fuel as you like.

Does it collapse?

I work in a small store front gym in a large city, and we have 3 floors of residential apartments above us. I was wondering if it's possible to harness the energy produced by the members using our cardiovascular equipment, and then turn it into usable power for the residents above us. The thought is part of a larger picture, building 3-story apt. buildings with healthclubs on the first floor, where the building is totally powered by the output of the gym patrons. Not only would this provide an alternative to oil-dependency, it might help with that whole obesity thing that we seem to be suffering in this country. Maybe gym membership would be complimentary to residents, or utility bills would be variable, depending on the amount of time spent in the gym, working out. What do you think?

1. What must be the value of m so that x+y is a factor of x^m - y^m?

2. Show that x-t is a factor of x^n - t^n for any positive integer n.

3. Show that x+t is a factor of x^n + t^n for any positive odd integer n.

I don't know how to do no.1 using this theorem, although I do know the answer. And are there any special things to note for nos. 2 and 3, or do I simply show that if P(x) is the polynomial and x-t is a factor, then P(t) = 0?

Thanks!

Choose the correct statement from the following:




a. At the temperature of liquid nitrogen argon will also be in the liquid state.
b. CO2 never exists as a liquid, as it always changes directly from solid to gas.
c. In the experiment to be performed if both Ar and CO2 were allowed to reach the temperature of liquid nitrogen, both would sublime when removed from the liquid nitrogen.
d. The triple point has the lowest temperature and pressure coordinates at which the liquid state can exist
