I’m not a racist because as a boy I was too slow when I was gokarting…

They get eliminated at first sight!

Are you sure about that? From m/s to km/h you multiply by 3600 (for the time) and divide by 1000 (for the distance) which leads to a factor of 3.6.
Personally i always remember 25 m/s = 90 km/h = 56 mph because of the somewhat round numbers.
Sooooo, wavelengths (λ) become longer when something moves away (redshift) and become shorter when something moves towards you (blueshift).
For a red flag (λ0=610nm) to become a green flag (λ1=549nm), it has to move towards you quite fast. But how fast is ‘quite fast’?
Using the formula
flag_velocity / speed of light © = difference in wavelengths / starting wavelength
we get
flag_velocity = (610-549) / 610 * c = 61 / 610 * c = 1/10 * c
This means: the flag has to move with about c/10 = 30 000 000 m/s = 108 000 000 km/h = 67 108 100 mph. Yeah, that’s quite fast.
(Disclaimer:
use info on own risk
values for λ were chosen in a way to make calculations easy. There is no info on what shade of red or green the flag is. The final result will be about the same.
With speeds at around 10% of c, I should use the formula considering the relativistic doppler effect… However, i wont. Thanks.)

Doesn’t matter what Ukraine is doing - Russia should just fuck off and go home.
Unfortunately your explanation is wrong: the reason why satellites in low earth orbit fall back to earth is, that in those heights (about 500km above earths surface) the thin remaining atmosphere creates drag and slow the satellites down.
About gravity: gravity is the reason, why satellites even stay in orbit and keep circling the earth. Without gravity, all the satellites would just fly away.
Maybe she wasn’t able to start collage sooner… There are many reasons for why s1 is at collage at 29.

The map does not make any mistake!
I remember it like this:
Finals - 1 match - 2 participants
Semifinals - 2 matches - 4 participants
Quarterfinals - 4 matches - 8 participants
Round of 16 - 8 matches - 16 participants
Round of 32 - 16 matches - 32 participants
In every round, half of the participants are eliminated and the other half moves on. Also the number of matches is reduced by a half every round.
Did the same some years back. Only black and white laser, but this thing just works!
Make purple yellow and one of the reds purple.
Care about how this a-hole blocks the sidewalk? Yes!
Care about accidential scratches or dents when walking around that pickup? No!
To add further more: often also 810 or 820 numbers exist, where a phone call might have a toll up to 10 or 20 cents per minute respectively. With 900 numbers you usually dont know, how expensive they are, when only looking at the number.
