Are both wheels planted on the ground? If so, then neither wheel will be moving faster than the other.
Also people look down to create and look up to remember. |

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

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. |

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 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? |

| 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. |
