Genial! Ist mittlerweile Teil meines alltäglichen Wortschatzes 😄

My favorite is using “Windleitblech” for spoiler.
Might be the wrong answer, but I think it’s kind of a signature of the creator… Sth with insta in his name
I see so many ad posts on lemmy now… They have to do something about it. This one is particular bad tho…
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.
Totally agree with you!
And he waddled awayyyy, waddle waddle waddle
What would those certain addons be? Just so that I won’t do anything illegal by accident.
Also, the closer you are to the trailer, the safer you are! Because the speed difference is much smaller, when you touch the trailer!
I’m not a racist because as a boy I was too slow when I was gokarting…
It’s “ich_iel” on feddit.de
They get eliminated at first sight!
Second motorola moto G. Imo they just work, not a lot of bloatware and a somewhat decent camera. I just dont get their model numbering anymore…
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.
So did you have to pay all of this? (~$14600 if i did the maths right) Or can you negotiate?
