the 1<--- over here can be the exact same as the 1<---- over here. If this is true for 1=1 then how does it effect the rest of math equations with ='s in them? I think there is alot we are not compensating for in math and that everything we have been taught could be wrong. Not that I have a clue what the truth would be tho.

I don't understand something...can someone clear this for me?

so, what galileo did...He dropped 2 objects of different masses which fell down at the same time,which proved that the time of descent was independent of their masses.

But, in that experiment, shouldn't air resistance have slowed down the lighter object because of friction? help!

How large of an E.M.P. can we generate without the nuclear explosion. (N.N.E.M.P.) Non nuclear electromagnetic pulse And does anybody have any good websites as to where I can find this information. I would like to know also if it is possible to generate a very small E.M.P. say like at home. I am very interested in any input that you guys can give me. P.S. not homework just curiosity

bonded end-to-end to make a single bar. The densities are 4.3 g/cm^3 and 6.3 g/cm^3. What length of the lighter-density part of the bar is needed if the total mass is 13103 g? Answer in units of cm.

I'm not even sure where to begin(but I have filled four pages...and about 5 hours trying).....so far I have figured the volume as 2463.00864 (I THINK that's correct). It seems to me that you would have to figure a percent or a portion of each of the densities and possibly set it up in an equation that is equal to 13103 g, but I can't figure out how to get what percent or portion of each individual density to figure this, or if that is even the correct way to figure it.
THANK YOU for any and all help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I'm having to use the encyclopedia to look things up. Is it supposed to be this difficult to comprehend?

No, I'm not planning a poaching expedition, it's research for a novel. Currently I have her sticking her hunting knife up the roof of the rhino's mouth. Would a hunting knife be long enough to reach the creature's brain? I've seen it done before with things the size of swords, like in Harry Potter and the Chamber of Secrets.

(I know that a real rhinocerous would not actually open its mouth to roar at her, but this is a demon in the form of a rhinocerous.)
