because. there is .1 and .01 and .001 and .0001... and .2 and .02... there is no limit to how precise you can get.

yes.

three guys are serving a life sentence in jail, one of them is blind. a gaurd comes in with 3 red hats and 2 white hats. he tells them that he is going to put one hat on each of their heads, they each get to see the color of the other two prisoners's hats, but not their own, except the blind dude, who is SOL. he tells each of them that if they can guess the color of the hat on their head he will let them go free, if they guess wrong they die, if they say nothing they stay and serve their sentence. The first dude guesses, gets it wrong and dies. The second guy also guesses, also gets it wrong, and dies. The third guy (the blind one) guesses the color of his hat and goes free. what was the color of the blind mans hat and how did he know?

this is part of the reason i dont belief in space time dialation. if time has a speed then it would be something like sec per ??. i have no idea what it would be for the "??". one thing i can promise you though, time is not measured in meters (i dont care if "the smartest man in the world" says so, so dont bother bringing it up).

hate to break it to you, but thats how it works. as a matter of fact, im shocked that i would even have to explain this. this is what they teach you in like 5th grade for how to work with units in equations. conversions are done this way. miles per hour to miles per minute: m=miles M=minutes h=hours 100m/h / 60M/h 100m/h * h/60M 100m/1 * 1/60M (h's cancel) 100m/60M (100/60)m/M 1.66m/M 1.66 miles per minute get your facts straight, this is how you do correct units in word problems. although i agree there is no meter equivalent of time.

i dont know about lab activities but my physics teacher had a lot of really fun demonstrations. for pendulums he had a chain hanging from the ceiling with a bowling ball on it. he would have us stand a few feet from it, raise it to our nose and then let it go and have us stand there as it came back without flinching. the guy above me said something about lazers, mirrors and cool designs. he did this thing with a mirror attached to a speaker, played some music with a strong beat and turned off all the lights. really cool. with the chain in the ceiling he demonstrated rotational inertia with a bike's front wheel. attached the chain to only one side and got it spinning to show us that the inertia of a spinning wheel can keep it vertical when it would otherwise be hanging on its side. light detectors hooked up to a speaker, laser pointer hooked up to the microphone port of a tape player. play music from across the room, show that it stops when the beam is interrupted. he did something with electrical charges, i dont remember the specifics but it involved a doll hanging from the ceiling due to an electro-magnet, he shot something out of a charged tube at it and the doll fell when it hit. not sure how that one worked. shopvac hovercraft. im not going into details here, but im sure you can find designs online. make sure to throw things at students who fall asleep. if i think of more stuff ill post it. i have never had the pleasure of witnessing this one, but have been told about it from others: put a balloon over something in which electrolysis is taking place, give a lecture on electrolysis as the balloon fills, at the end of the lecture, light the balloon.

i personally think things like that are a bit extreme. we trim my dogs nails, why cant you trim your cats? or get a scratching post. the one i really dont like is removing a dogs vocal cords. totally across the line. when i was selling coupon books for soccer i went up to this house with a dog that just kind of stood there doing the bark motion with its mouth but making no more than a breath kind of noise. i had trouble not slapping the woman who answered the door. im all for spaying/neutering though.

"instead of using seconds, use it's meter equivelent" what in the world are you talking about? why would you do that? since when is there a "meter equivelent" for seconds? what is the "meter equivelent" for seconds? answer these questions and i might be able to help.

the half angle hits first, less of its force is pushing up, which means less time before upward velocity=0(when it starts heading back down) which means less time before it hits bottom again. lets say velocity=10f/s. vertical starting velocity on the 90=10f/s t=time in secs vertical position =10t-16t^2 when position =0 it is on the ground 0=10t-16t^2 0=t(10-16t) t=0(right when you shoot) or 5/8=.625(when it hits) 5/8 sec= impact vertical starting velocity on the 45= 10sin(45) position=10sin(45)t-16t^2 0=10sin(45)t-16t^2 0=8.509t-16t^2 0=t(8.509-16t) t=0 or 8.509/16=.5318 secs 90 hits at .625 secs 45 hits at .5318 secs been a few years since physics, im sure the 45 hits first but my exact numbers may be off, anyone got any corrections? edit: doh, -16 t^2 is gravity in feet, 9.8 for meters, there: were going with feet, yay america.

yeah, those too. (i think catapults are closer to highschool ability though)

good ideas, but it doesnt seem to me that the ribbon will do much good over so short a distance, maybe if they were dropping it off the roof or something, or maybe im just wrong : P. while i agree that the guy can go to hell, i have to admit i have been irritated by yt's posts before. i find he likes telling me im wrong but not ever explaining why. just my 2 cents. bubble wrap sounds good, or just tape the straws around the egg in a big wad. it probably doesnt need to be terribly organized for this. something i heard of before, with more tape, was a group that just had the egg with 6 feet of tape attached to it. hold the end off the tape 6 feet of the ground and drop it, the egg drops 0 feet, you get your grade.

catapults.

i dont know what equation that happens in, but if it does i assure you its supposed to. for example, if i am going 20m/h for 20 miles how long does it take me? x=20m/(20m/h) x=20m*(h/20m) x=20mh/20m ("20m"s cancel out) x=1h the miles are gone and im left with my answer, in correct units.

are you asking why we use m/s or why we use units at all? what units we use depends on the magnitude of the speed/distance/whatever that we are measuring. we use units so that when you get a number out the other side you know whether it is acceleration (m/s^2) or velocity (m/s) and you know whether that 1000mph or fps. it makes a difference.

how does one light said grenade without blowing ones hand off?

i have an ok understanding of many aspects of a computer, but not ones that would require me to be a "leet haxxor" sorry.

how do i get winamp source? : P

ill give it a shot, but i really want to know how to do this stuff. how do you make a flood fill efficient enough to use for something like that?

no, there would be no velocity at either end, there should be no acceleration for one instant in the middle, when no forces are acting on him, then his velocity carries him through and he starts accelerating back toward the center again.

well, its deffinately possible to make a new OS. highschool kids do it sometimes. as for those features, they all seem possible, some may be harder to come by than others.

super... english?

actually when its filling in the space nothing is moving and no colors are changing. it moves the curves, fills them in with that color, then moves and color shifts again. there are no changes taking place while its filling in the pixels.

air resistance is the only thing that makes it so he will eventually stop. air resistance creates this thing called terminal velocity, without which he would build enough speed on his plunge to overcome the gravity at the center and "fall" back up to exactly the same height again.

i can get the randomly moving things, i can make them random colors, i can make the colors randomly fade from one to the other. its the flood fill function im having trouble with. i cant make it fill a space in less than about 30 secs(depending on the size of the space obviously). keep in mind the space were talking about isnt square, doesnt have straight edges, and can be any size. how does paint do it so quickly?
