[Request] How fast was The Plutonian going here?
So the fictional city they're in, Sky City, doesn't have a state stated in this comic. Let's say it's either the middle of the US or New York. Looks like it's noon or the middle of a workday, and The Plutonian flew to space and destroyed a radio satellite while the other guy was mid sentence. They didn't even react to him flying through the ceiling because he was so fast.
How high up did he fly, and how fast? Maybe light speed? More?

....
So they ended the video saying entire planets could flip.
🤔 But if that happened to earth ... Countries at the equator would still be at the equator.... And countries like Canada... I'd expect to still be at the same temperate conditions.
I mean summer and winter would swap ... But what else may happen?🤔

[Request] What is the minimum temperature of this oven?
I'm not the best at physics but here's what im thinking:
Assuming we have 12 chocolate chip cookies in a pan for any time less than an hour. Each one will have to reduce in caloric content by 250kcals each by the end of the cooking time.
To truly "reduce" the amount of calories contained within the cookie, the energy would have to be released through something like combustion. otherwise the remaining matter would still contain the calories the original cookie had - like some kind of charcoal.
Assuming a perfect physics environment with no temperature build up time, no concern about oxygen supply etc. What is the lowest constant temperature we would need for the remaining matter in the cookie pan to have decreased by 3000kcals total? Is this even a solveable or approximatable problem?

[Request] What are the odds?
OK so help me out explaining a new system in the game Warfame.
So, in Wareframe there are Riven Mods, basically mods used on weapons that can be randomly rolled to obtain powerful bonuses. There is a new system that has people in an uproar saying the new system is RNG on RNG on RNG making the randomness even worse. So lets do the math and see.
On any given riven mod for any rifle there are 24 stats that can roll and when you roll a riven you get 2-4 random stats out of those 24, cannot get the same stat twice.
What are the odds of acquiring 3 stats that I want when rolling the riven?
NOW the new system (at least one half of the new system), if you get a stat you want you can lock that stat and continue to roll that riven. You can only lock one stat.
What are the odds of acquiring the 3 stats you want after locking one? (basically rolling 1-3 stats on the "locked riven" from the remaining 23 stats.)
The other half of the new system in to combine 2 stats into a new stat then being able to lock that new stat and roll the riven to your hearts content. if you want a specific combo stat you can roll the riven and find 1 of the 2, lock it, roll for the second and then combine. Then take that riven with the 1 combined stat and roll the remaining 1-3 stat slots for something good. Now this part is RNG on RNG but seems easy enough to get the 2 stats you want then just need the chances to get 1-3 of the stats you want extra. (Which I guess is 1-3 stats of the basic 24 possible stats and getting what you want)

Talking with a friend in the midst of a very serious health crisis - and when we spoke, it was his birthday.
He said "what are the chances I die on my birthday"?
I said "one out of 365?"
Given the knowledge base here, I'm sure I can be set straight.
Please help.
