I mean a regular toy balloon, filled with Helium. How high up does it go? What happens at maximum altitude? Please cite your source, if you don't mind. My 3 year old let his "Trader Joe's" balloon fly out of his hand in the front yard yesterday, and is demanding a full explanation as to why Daddy was unable to retrieve it. No kidding.

A and B have position vectors (3i + 6j -8k) and (8j - 6k) respectively.

The line L1 passes through both these, and I have found its equation as (3i + 6j -8k) + s(-3i+2k+2j)

The line L2 has equation (-2i + 10j + 6k) + t(7i - 4j + 6k)

I have found that these lines intersect at (-9i + 14j) and s=4, t=-1

The point C lies on L2 such that AC is perpendicular to AB. What do I need to use to find the position vector of C - I think it's the dot product/scalar product rule but I'm not sure, and if it is, which vectors do I need to use?

Hi people, is anyone of you here very good with experiments using the ballistic gas gun?

I am supposed to fire a small cylindrical shaped projectile through the barrel. However the diameter of the projectile is smaller than the barrel's inner diameter, so I have to make use of something called a sabot... the sabot has the same diameter as the barrel's inner diameter and it has a small hole in the middle for my projectile to sit in... Normally that solves the problem, but for my experiment, I have to strip the sabot off the projectile after it leaves the muzzle... I tried many ways of doing it but most of the time, the projectile path gets affected after the sabot has been stripped off, ie. the projectile either deflects or tilts.

Anyone knows of a way of stripping the sabot such that it will not affect the flight path of the projectile?I need to achieve a perfect head-on collision.. Your help will be greatly appreciated...

Thanks a lot!

The ark would have had to carry at least two of each species (7 of 'the clean ones' according to the bible) including modern animals through to every kind of dinosaur. Peronally I find this story extremely improbable, but this self acclaimed 'scientist' insists that it really happened as depicted in the bible.
