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 (c) = 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.)
Red flag: My friend once saw what looked like people setting a RadioShack ablaze and stealing all the expensive electronics and making off with them all.
Green flag context: It was actually a faulty electronic that caused the fire, and the "thieves" were Good Samaritans saving everything from getting burned.
Oh. I'm not sure. That's the least they could've done though, considering someone posted a video of them saving the electronics and ruined their reputation. Made worse because they were loyal AA immigrant employees in a community that was growing unfonder of the immigration and the perception of what they were doing caused things to skyrocket.
The idea of anyone helping was a business liability concern, but the insistent bystanders wanted to balance that out with anything they thought they "could" do. Both the firestation and the police (because they had nothing else to do in their tiny area) were called but took a while because Winter was in its cusp at the time.
Ironically it was the fact the police understood the bystanders' intentions that made citizens (who thought it was a burglary) accuse everyone in charge of being overly sympathetic to what they thought was immigration-spawned crime. Police even made a public statement about the bystanders' intentions, but the citizens didn't believe the police on that.

Well, instead of moving the flag, we could collapse the space in between us rapidly. Would that be easier? I think I have some dark energy around here somewhere...
If your partner is indiscriminately murdering vaguely shady people with a bow and arrow it will probably be fine, cause he’ll reset the universe and become god (or something?) just be sure to weep about being betrayed at least once every seas—er… year.
They're very giving, and will do you so many favors, and cater to your whims. Favorite ice cream? Let me go buy it for you! Need something from the store? I'll go get it! Need a ride? Got you covered!
Once they have you "locked down" (married, pregnant, in a long-term lease, dependant on them for transport, etc.) they can do a 180 and suddenly "you owe them". No more favors. Only guilt. They'll isolate you and make every negative emotion they feel be "your fault."
They want you to become dependant on them so they can use and manipulate you.
Be so very careful with overly kind/giving people. Never let yourself be 100% dependant on someone else. Ever. No matter how nice they are to you.
The race was planned to run for 44 laps, but ended during the third lap due to wet conditions. Laps one and two took place behind the safety car before a red flag stopped the race on lap three. The sporting regulations required the results be taken from the end of lap one, with half points given to drivers who finished in the top 10 positions as less than 75% of the originally scheduled race distance had been completed.
Hating the democratic party of the United States. Without any other context you would assume they are a republican. But once they start critiquing marx and explaning how Trotsky's permanent revolution is the only viable path forward you know they are good people.
Alternatively, if someone supports the dems no matter what, that is a red flag that should never be overlooked especially when they start rationalizing their perverted beliefs by name-dropping minorities out of the blue.

pssst hey you missed the conversion from seconds to hours, your answers are in kilometres/miles per second and need to be another 3600 times larger.
neumast@lemmy.world · 2 pts · 2y
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.
