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 :D.
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 :p)?
-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 |

isn't it in psychology that they say a person is trying to focus and that's why they look upward? when they look downard they're lying. |

im pretty sure it gets higher, because think of when you have an empty wine bottle (assuming you have ever blown in it) and its pretty low, i dont think it would get lower but would get higher when you filled it up. an easy way to check this one out would be to go get yourself a wine glass, and try it....
about 5 mins of work

A bottle is different than a wine glass.
Blowing is also not the same as rubbing the edge.
You mite be right, but it just seems to easy then. |

1) Higher tone
2) Depends on which way they look (left vs. right), although the way it's worded, I suspect the answer would be "to focus better"
3) Cold water is ideal, I notice I get sluggish and tire more easily when I swim in warmer water. I'd say the swimmer would go slower, but since the swimmer is strong, probably make it.
4) No idea
5) Both wheels will spin with the same angular velocity. The same size indicates both have the same rotational inertia. I'd say they'll spin equally "hard" - whatever "hard" means.
6) 3/4 - First you have a white ball. From that you branch out into the two posibilities inside the bag - white/white, and white/red. Then you have four total possibilities for pulling out a ball - white, white, white, or red.
7) No idea |

No that's correct, think of a trombone player - basically all you do is enlarge or decrease the size of the wind pipe. Since sound travels at a constant speed, the decreased size will cause it to resonate at a higher rate inside the wind pipe. |

eh by harder i mean faster..sorry, translating from dutch to english sux if you do it fast.
Oke seems we agree that question 2 is Focusing.
Getting mixed answers on the Tone thing.
Yes the questions says an experienced swimmer.
Thanks, i'll be off to sleep now will check back tomrrow :). |

I thought it was looking up and to the left was lying, and up/up to the right was recalling memory. Only correct about 60% of the time though, from what I remember. |
