we all think we know question #2 from the Negotiator...

Sam L. Jackson (Lt. Danny Roman) is asking J.T. Walsh (Insp. Terence Neibaum) [also in ...Needful Things, Outbreak, Blue Chips, A Few Good Men] up in his corner office asking him a question at gun point and then refers to how he knows that when a person looks up and to the left they are accessing their memory lobe of their brain and when they look up and to the right they are accessign their creative frontal lobe of the brain,...

as far as me knowing any sort of answer i have no idea on any of these,.. i just remember this movie

although with the balls i want to say 1/2 but thats my shot in dark guess

-3/4

THERES HALF A CHANCE THAT YOU WILL PUT A RED BALL IN, THEN HALF A CHANCE YOU WILL PULL THE WHITE BALL OUT (1/4 CHANCE RED BALL STAYS IN BAG, THEREFORE 3/4 CHANCE WHITE BALL STAYS IN BAG)


Remeber you take out a white ball, and there is one in before. So basicly it doesn't come into it. So therefore there is a 50/50 of either a red or white ball being put in and remaining.

Ondrayce, the wheels are equall in everything, size , pressure etc. yes they are planted.

with harder i meant faster, sorry hehe

I'd like to thank everyone for helping

The ball question i thought about this now.

There is one white ball already in the bag.
You'd take a red or a white ball and put it in the bag, here comes the chance factor. You don't know which ball you took, and it can be 50% from here.

Then you have a bag with 2 balls , one with a white one and one with a ball with a color that can be red or white. You'd take out a white one.

Now lets say you took out the white one that was already in it. Now it can be 50% red or white. Now lets say you had 2 white balls in the bag, there is a 100% chance of picking out a white now, but you don't know this info. So the other ball can be red and thats still 50%.

so am guessing 1/2

With the bike question...
It says the bike is turning, so the front wheel will travel in an arched motion but the back wheel will get from A to B in a straighter line so will travel a shorter distance. If you imagine sitting on your bike without moving, and putting the wheel at a near 90 degree angle and then start to move, you will see that the front wheel does most of the movement but the back hardly turns. Imo this is the same principle.

-1/2
-2/3
-3/4


My answer is 1/2. Going on the picture that somone posted above, if you remove one of the white balls from each combination, then there are two left, 1 of which are white, and one of which is red. does my reasoning make sense?

That question is worded a little tricky, but my interpretation of it is 1/2.

-The tone will be higher

The sound is made by the amount of vibrating glass between the top and the liquid's level. If you decrease the amount of vibrating glass you increase the frequency of its vibration and also the tone.


Oke Second question.
Why do people look up in the sky when you ask them a question? (I hardly notice this tbh, but that�s the question)
-To focus better.

Third Question.
A good swimmer tries to swim 6 kilometers. The water has a temperature of 37 degrees Celcius. What will happen?
-He won�t make the finish.

There is no way a swimmer could swim 6 kilometers in an environment of his own body temperature. In water, your sweat cannot evaporate to cool your body, only the ambient temperature of the water can do that, which in this case it wouldn't. It would be like running a 6 kilometer race when it's 37 degrees out and not being able to sweat.


Fifth Question.
Which wheel will spin harder? If you take a turn with a bicycle, both wheels are equally big.
-The front one.

I'm assuming that you wouldn't be traveling in a straight line only. If you turn at all, the rear wheel acts like a pivot around which the front wheel moves. Thus, the front wheel would have to move faster.


Seventh Question.
Why do pidgins bounce their heads when they walk?
-To stay in balance.



I'd have to get back to you on the other ones.

Either my answers are revolutionary and far ahead of all of the rest of you or I suck at science. I am going with the second.

Doesn't a black and white TV display color.

Because Black and White are colours?

Black and White ARE NOT colours.


Posted by Dervish on Dec-08-2004 16:18:

Opps about the bike question I for some reson thought the bike was turned upside down with the wheels in the air and you were spinning it with your hands..... dunno why. It'll be the back cos it's the driving wheel and will slip quite a bit, the front will just roll along. So the back will do more revolytions for a given jounrney and thus travel more.

White is all the colours together hence not a colour. Black is no colours hence not a colour.

Ya something with light absorbtion?

black absorbs all colors, and white repels right?

massive, post the right answers when you find out for sure.

Black absorbs light, not color, and white reflects light.
Physically, black is a combination the three primary colors, red, blue, and yellow, and is still considered a color, but white is nothing. With light, like what's being projected on your computer monitor, it is the opposite.


Posted by Phil r on Dec-08-2004 18:49:

erm...nup, the opposite.

white is a combination of all the colours. which is why if you shine white light through a prism, you get a rainbow.

black is the absence of colour. which is why, if you shine a black light through a prism, you won't see anything.

and the answer to all the questions is written below.




























































































42.

black and white are indeed shades/tones, not colours.

the pigeon question, it's to keep balance

the bike question, the front one will spin faster because the back wheel is the one that's attached to the chain and, therefore, the one that needs more force.

the swimmer question, he'd probably swim faster. the water really isn't that hot, but in fact, at body temperature. it's the average temperature of an olympic-sized pool, so i'd go with faster.


and, yes, 42

Yes, when dealing with light, like I also said. But try mixing red, yellow and blue paint together and coming out with white.

Right. I don't know if this has been explained. Colored light is light that has been passed through a filter. Red light is a light that has been passed through a filter that filters everything except red. Paint, or color on an object is the opposite. It reflects light. Red paint absorbs all colors but red, it reflects red light and therefore that is what you see.

Light - All colors together = white, all colors filtered = black
Paint, etc - All colors absorbed = black, all colors reflected = white

yes true, but each color has this opposite color that can make it white.

Complimentaire kleur (color) called in dutch. I believe Red was green? and bleu has yellow. and vica versa of cource.

if you put these 2 colors together on a cd or something and spin it really fast, youl will see with your eyes during the spinning that the 2 colors will turn white. If you stop you will see the 2 colors again.

Oke from our school we received a quiz that we may answer and we can win prizes.

There are some questions we can try to solve, ya I mite win a prize, but some of them are fun imo.

I�ll put the questions where I need an answer from, any help is welcome .

A wine glass will produce sound if you rub the edge of it with a wet finger. What will happen with the tone if your going to fill the glass?
-The tone will be higher
-The tone will be lower
-The tone will be the same.

Probably a sound engineer question, but my guess it would be lower.

Oke Second question.
Why do people look up in the sky when you ask them a question? (I hardly notice this tbh, but that�s the question)
-To avoid a question
-Trying to cover up a lie
-To focus better.

Third Question.
A good swimmer tries to swim 6 kilometers. The water has a temperature of 37 degrees Celcius. What will happen?
-He will swim slower than he expected.
-He will swim faster than he expected, because the temperature is ideal for his mucels.
-He won�t make the finish.

Fourth Question.
How can you display color in a black-white television(those old TVs )?
-By sending a Chromodigital(translating it directly from dutch, no clue what it is) with the screen.
-By turning on and off the color siginal with a rate of 50 times a second.
-By displaying really fast black and white areas.

Fifth Question.
Which wheel will spin harder? If you take a turn with a bicycle, both wheels are equally big.
-The front one.
-The rear one.
-Both wheels spin equally hard.

Sixth Question
You have a bag with a white ball in it. You put BLINDLY a red or a white ball with it. Then you take blindly a ball out from the bag, and this ball seems to be white. How big is the chance that the ball that got left in the bag, white is?
-1/2
-2/3
-3/4

Bleh maths., probably 2/3?

Seventh Question.
Why do pidgins bounce their heads when they walk?
-To stay in balance.
-Try to impress other pidgins
-To see things better.

Oke guys and girls that�s it, if anyone know some of them, would love to know J. Especially the second question, could be all 3 IMO


1. The tone will be lower.(educated guess)
2. To focus better. (focusing is required to tell a lie or avoid a question.)
3. He won't make the finish.(He'll overheat before he can get too far.)
4. No clue.
5. They both spin equally hard.(If one spun faster than the other, u wouldnt be able to go very fast, with one wheel contradicting the other)
6. 2/3(u have on already in there. u add in a red or white one. then take one ball out. 2 white balls to 1 red. i may be wrong.)
7. To stay in balance.(their legs are disproportional to the rest of their bodies making it awkward to walk.)
