Science & Mathematics - 4 February 2007

* I believe the natural causes are behind the global warming, as by watching some programs nowadays transmitted on UKTV history channel, showing :-
1- That the temperature of the sun is increasing, which leads to the earth receiving more heat than before, leading to its warming.
2- The earth was passing through different ages (ice age, water age) & the natural changes still continuing to occur.
* so not the fumes from my , your car & the air flight, which I have to pay £40 (increase in tax/UK), as by paying that will not sort the matter out!
* man made CO2 might come by chance of the existing natural warming (the timing of it).
* But man made CO2 consists an easy excuse for the governments to rob their citizens! What a shame.

In about 3 billion year Andromeda galaxy will collide with our MilkyWay.

Of course, i doubt whether humans will survive until then, but however i need to know whether what kind of effect it will have on Earth?

Is there a chance for it to be safe as there is a lot of empty space between the two galaxies?

figures? It's physics, and the problem is 42.3 x 2.61
when I multiply it out, it is 110.403
I have to round that number so that there are only 3 significant figures. When I rounded to 110, there are only 2 significant figures, and when I round it to 110.4, there are 4 significant figures. Please help!

How can I calculate the amount of input force I would need with each turn of the handle and the total amount of force to raise the books with the distance of 20 cm.
the handle has a circumference of 150 cm., the pitch is 2 cm. and the books weigh 10 kg.
would it be F=2pir or W*P/2pir
If i used a pulley system using the same books which one of these machines will have greatest mechanical advantage.

Do you believe in Phil? Are groundhogs believable?
Punxsutawney Phil's official forecast as read 2/2/07 at 7:28 a.m. at Gobbler's Knob:
El Nino has caused high winds, heavy snow, ice and freezing temperatures in the west.
Here in the East with much mild winter weather we have been blessed.
Global warming has caused a great debate.
This mild winter makes it seem just great.
On this Groundhog Day we think of one thing.
Will we have winter or will we have spring?
On Gobbler's Knob I see no shadow today.
I predict that early spring is on the way.

Are you as cold as I am right now?

geometric progression

calculate the number of terms of the geometric progression 1/4,1/12, 1/36....,1/324.


for the geometric progression 500,100,20... which term will be less than 1/10 for the first time?


how many terms of the geometric progression 48,24,12,...must be equal for the sum to be equal to 95/1/4?


the third term and the 6th term of a geometric progression are 27 and 8. find the second term.

the amount if the insurance coverage for a newly bought imported car in the year 2001 was rm120 000. the amount insured for each of the following years will decrease by 5% as compared to d previous year. calculate the amount insured for the year 2009.
