This question was from an IQ test I took. I scored a 138 which is only 2 points shy of genius. I remember being able to correctly answer just about every question except for this one. I had to guess, please don't answer if you are guessing and if you know the answer, please enlighten me as to how you came to your answer:


John likes 400 but not 300; he likes 100 but not 99; he likes 3600 but not 3700. Which does he like?
A. 900
B. 1000
C. 1100
D. 1200

I ask this because I have been curious what problems might arise when designing a space elevator. If you have a counter-weight in geosynchronous orbit with a ultra-strong/ultra-light cable hanging from it down to Earth's surface, we would need quite a bit of cable in reserve to account for the elliptical orbit of the counter-weight, right?

If you could figure out approximately the difference between the major and minor axes, that would satisfy my curiosity. Or if you could point me in the right direction, I could scrounge for my old physics notes with orbit equations.

Good article about space elevator:

Another question of mine about probable space elevator issues:

Solve the system by addition or substitution.
x – 4y = –7

20,12,8,6,?

Which number fits better at last position, following the 6?

Please, EXPLAIN your result. Best solution wins 10 POINTS.
there will be no best answer if you don't explain how you get

More importantly, I would like to share with you the Truth about the afterlife. I only tell you this because I care what will happen to you when you die. Have you ever told a lie, stolen anything, used God’s name in vain? These are just a few of God’s Moral Laws. When you die, God will judge you on the basis of His Moral Law. If you stand guilty before God of breaking His Laws, He will send you to Hell. If God is Just and Holy, He must punish lawbreakers. The good news is that God provided a way for you to be forgiven and go to Heaven. Jesus Christ died on a cross and rose again to pay the debt for your sins and take your punishment. What you must do is Repent, which means to say you are sorry to God and turn away from your sins. Then put your complete Trust in Jesus Christ. Only then will you be accepted into Heaven, not because you’re a good person, but because you’re a bad person who’s been forgiven. Please give this some thought. Your Eternal Destination depends on it.

Is there anywhere online that explains architectural drafting or how to draw floor plans? (Manual, not CAD)

If anyone knows, are there certain ways to draw things when you're doing floorplans? Are there right and wrong ways to draft a building? Any general information to get me started would be great.

Do you believe in dreams being warning or messages? I have dreams that i interprit and they come true exactly as the dream said. Daniel and Revelations have a report of the future which happened in the same way and Other things that haven't happened and we know about them and we can't stop them from happening.
Is this because they happened already and so we have no controll?

Ok, I copied my physics question from the board and I'm trying to solve it but I can't read my writing for one of the numbers...

I'm not sure if it was :The ship is travelling north with a speed of 48 metres/second OR 4.8 metres/second.

1. A flea jumps from a mouse with a velocity of 4 m/s (East) relative to the mouse. The mouse is walking on a crate that is being pulled at 2 m/s (East 20 degrees North) across the ship. The mouse is walking 1.5 m/s (West 30 degrees South) across the crate. The ship is travelling north with a speed of 4.8 m/s OR 48 m/s and there's a current of 1 m/s (West 40 degrees South). What's the velocity of the flea relative to the ground?

Can you guys please tell me which sounds more logical...if the ship was travelling at 4.8 m/s or 48 m/s. Thanks a lot.

If you guys can actually help me in any way solve it too, that would be even greater but maybe that's asking for too much... anyways thanks a lot for any help!

Tons of trees down, there is a downed power line, and my neighbors fence is totally destroyed. There have been tornado warnings in my area, but you never think it could happen so close to home, you know?

I'm interested in anyone's personal experience with one....thanks.

Guess I'll be picking up lots of broken branches and debris out of my backyard this weekend...*groan*
