Can someone show me how I go about this? I know I need to put the number in for g but I dont want to end up with the wrong answer thanks to b
User avatar #3286 to #3285 - delio (11/09/2014) [-]
I get either b4-1 or b-5
#3288 to #3286 - frikandelspeciaal (11/10/2014) [-]
b4-1 is correct for the first one.

You just gotta remember that a negative number squared always gives you a positive number because basically:
(-x)² = (-x) * (-x) = x²

If you fill in the rest, i'll tell you if you got it right
User avatar #3289 to #3288 - delio (11/10/2014) [-]
ok thanks mate. I figured that was correct. The hard part was trying figure out what to do with the extra letter. Again thanks for responding since I know most dont like doing/helping others with math.

Has anybody seen the movie intersteller, I've got a few questions and im hopping some of you guys would help me to better understand some of the movie's concepts.

Best freaking movie I have ever seen, bar none.

What are your questions?

Spoiler Alert
When Matthew Mcconaughey and anne Hathaway went to the water planet with big ass waves they left romilly (David Gyasi) behind on the ship, he was just over the planet in space not that far away, how the hell was 1 hour to the guys on the plant, 7 years+ for romilly??
User avatar #3333 to #3278 - xtwinblade (11/23/2014) [-]
They were so near a black hole, that the gravity from the black hole caused time to tick slower near the horizon. since the ship was further away it didnt slow down as much.

like Simplify explained, it has to do with Relativity.

does that mean people on the international space station experience time differently then us?
User avatar #3334 to #3304 - xtwinblade (11/23/2014) [-]
Actually they do!
You know all those satelites that goes around the earth? Well the GPS satelites we use to locate ourself on earth have a clock on them which ticks every so slightly different than ours down on the surface of earth. So the scientist who sendt them up, pre-calculated the time dilation using Einsteins Theory of relativity.

So yes. Since the ISS is further away from earths gravitational pull, they experience time dilation,
User avatar #3274 to #3273 - kevintk (11/07/2014) [-]
I was just going ask the same thing. Can someone explain space time relativity and how gravity affects time? I'm pretty sure I'm retarded.

#3264 - KINGOFTHESTARS (11/04/2014) [-]
I guess this is the most appropiate board.

Anderson cooper and neil harris are just as gay as perez hilton (since gay is an absolute)
why arent they faggots? Meaning, why dont they prance around like bitches and act all flamboyant?

Why is it that some gays act like women? Are faggots just being faggots or will they be inclined to act like women?

If women werent acting in the manners thst our society deemed feminine, would gays still act in a faggoty manner that we know of now? Or woukd they act in thatnfeminie manner that differs from our own?

If you could follow, try to explain this. I ask because its annoying as shit that the guy who lives next door to me wont stop being a faggot.

Also forgive my "language" im dead-ass serious asking these questions.

#3265 to #3264 - subtard ONLINE (11/04/2014) [-]
Heterosexuals vary in how flamboyant they act too. The character Ron Swanson is probably the closest to zero flamboyance that I can think of. Daniel Tosh is higher up on the scale. But you can see from my graph that all gays are shifted to a similar distribution but at a higher flamboyance. I posit that once a gay person acts more flamboyant than the most flamboyant straight person, they achieve a state of superflamboyance which you may call a faggot
Within just the superflamboyant zone, as flamboyance increases, femininity increases exponentially. So I think gays only act more like societal females once they surpass the critical flamboyant point. If women acted differently in society, only the superflamboyant part of gays would change.
User avatar #3270 to #3265 - KINGOFTHESTARS (11/05/2014) [-]
Wait, so gay flamboyance before super flamboyance does not equal femininity?
User avatar #3271 to #3270 - subtard ONLINE (11/05/2014) [-]
Mhm. Because if they're acting truly feminine they'll already be acting gayer than any straight man should.
User avatar #3272 to #3271 - KINGOFTHESTARS (11/05/2014) [-]
Thats gay.

is it safe to put nielmed and water into a enema bag and use it for a enema since it's just sodium chloride and sodium bicarbonate
User avatar #3275 to #3261 - coronus (11/08/2014) [-]
Probably not.

You would be drastically increasing the pH in your colon, and absorbing moderate strength base straight into your blood. While the blood is buffered against alkalosis, bicarbonate can settle acid reflux in fairly small amounts; so one can assume that blood, having a functional pH of 7.35 - 7.45, would be very sensitive to such an effective base.
#3277 to #3275 - luigipimp (11/08/2014) [-]
can i use just purified water?
User avatar #3279 to #3277 - coronus (11/08/2014) [-]
you could, but the best thing to do before trying an enema, or in conjunction with one, would be to use a stool softener and magnesium citrate.

If those don't loosen things up within 8-10 hours, then a water enema should be effective.
#3280 to #3279 - luigipimp (11/09/2014) [-]
i dont need loosening, just to cleanse
User avatar #3284 to #3280 - coronus (11/09/2014) [-]
In that case, go with the stool softener and magnesium citrate. It's the same combo used to cleanse the bowel for a colonoscopy, so it should suffice.

I got an exam tomorrow for chemistry.
It's about acid-base stuff.
It's mostly pretty easy, once you get it. Especially things like buffers and amfolytes.
But I'm still stressing pretty hard.
Anybody who's good at chemistry got any tips to increase speed in calculating pH?

Why does the exterior of a refrigerator hot but the interior cold? Hmmm? HMMMMM?
User avatar #3258 to #3252 - xsnowshark (11/03/2014) [-]
Because the purpose of a refrigerator is to reject the heat that is inside the fridge to the air on the outside. It's the same thing that happens with an AC unit.

Quick question:

If a person (a) of mass 130 kg and person (b) of mass 60 kg are standing a distance -d- from each other on a frictionless surface, and they are holding a light rope between them and they pull, the two people meet at a distance of 3.8 m from person (a)'s original position. How far was the original distance between them?

How do I go about solving this problem? I feel like the Fnet x) for both would be ma = Fpull 1 - Fpull 2, but I'm not really sure how to proceed.
User avatar #3249 to #3246 - carbohydrates (11/02/2014) [-]
Assuming they both exerted the same amount of force pulling them towards each other...
And also assuming my dumb brain is going about this problem the right way...

130/60=2.166, so then person B would be pulled 2.166 times the distance person A was pulled.
3.8*2.166=8.230m person B is pulled, add back in the 3.8m person A traveled, and you get 12.030m total.
Alternatively; 60/130=.4615, so person A traveled 46.15% of the distance person B will.
100 (% distance person B travels) / 46.15 (% of person B that person A traveled) = 2.166 (times more traveling).
Which leads back to 3.8*2.166+3.8=12.030m total distance traveled.

Or... To account for every decimal point 130/60*3.8+3.8=12.03333333 (repeating infinitely).
1/(60/130)*3.8+3.8=12.03333333

I just wanted to share, though it might already be known.
A couple days ago in Biology they spoke of a natural process in all cells called apoptosis, and from what I gathered, it's "cell suicide", a process in which a cell offs itself if it is damaged beyond repair or otherwise cannot function properly anymore.
Cancer causes this function to cease, well, function. So cancer = no more apoptosis. If someone were to figure out how to reinstate this key natural function to cancer cells, boom, cure for cancer. My point is, in this case:
suicide is the answer.
