as T_∞ = 0 , I use Q=−F\epsilon A\sigma T^4 for this problem as the integration is much easier, so we start with
mcdTdt=−F\epsilon A\sigma T^4
rearrange so T is on one side and t is on the other:
−mcF\epsilon A\sigma T^4dT=dt
on the left side I integrate from the initial temperature (Ti)...
So today I was holding up an umbrella near someone playing music, and it sounded like the music was coming from the top of my umbrella.
Is this a similar effect to a radio? Can it be seen as sound being a disturbance of the air that causes the metal to vibrate which amplifies it to make it...
Ah, ok. I didn't know much about antimatter other then it went away when combined with normal matter, so ya, antimatter doesn't sound like it makes implosions.
I hereby come to the conclusion that with our current understanding of physics logical implosion grenades are impossible.
The Thing...
Oh, that is slightly humorous, I said Archimedes and then forgot about his mirror towers. (That show that light can cause damage.(realized that sentance was horrible communication, but hopefully you get what I meant by "cause damage".))
I didn't think about it, but I guess if you had dense...
That is what I figured. (Especially on the third one. Unless through some magic you could convert it to light, in which case you are the <Tesla/Da Vinci/Archimedes> of this age. Would that work if we figured a way out to do that?) Forgot criteria for it to count as a grenade.
So here it is...
So I was reading some books with implosion grenades in them, and was wondering if they were theoretically possible.
Here are a few things I came up with from research and my own brain, the ones from my own brain may be garbage, and if so please let me know.
So apparently a light bulb is...
