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? |

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. |

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 :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 |
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.) |
