That system must be open to the atmosphere at the top. The contest is to see who can get the most pressure over an area of 10in^2 on the ground. The only thing you can use to get the pressure is gravity and the water. What shape would your system be and what would be the pressure on the 10in^2 area at ground level.

Is it possible for us to make a mega structure like football ground 2 or 3 independently (colony like structure for breading purposes) in the space, were we could accommodate different intellectual people, number of scientist and astronomies, to save human race. After astride collides in earth? Description of the field should be like: -Flat surface, Lab, maximum number of sample of plants and living creature, missile, soil, drinking water in a such a way to recycle all source of energy and shielded with Big and strong thick glass spherically covered to protect and to maneuver our possession like starships provided with fuel as much is possible. Is human race will survey this? What steps have been taken so far?
I know that I will not alive so long! But what happen to us???
I believe you will answer my question.Thank you

Are there any interesting effects of micro-gravity? Any experiments done, e.g. release a few foam balls and see if they drift to the center of the station?

Draw graphs in their time and frequency domains.
Time domain
h(t)=5Cos(2pi(6)t)

Frequency domains
h(f)=5/2(sigma)(f-6pi)+5/2(sigma)(f+6pi)

Ok I would love to know why yahoo answer removed a question about my theory of gravity part one.
thist was a question not a statement as asked "what do you think..?").
The only conclusion I can come up with is that some jealous little academic **** got annoyed because I was able to think a lot deeper than he or she and reported it as abuse
just because they pass a few multiple choice question and get their degrees they cant stand someone who is a lot smarter.
I can tell you how some of these graduates act as I have to deal with them.
firstly they get drunk, have house parties to all hours annoying the neighbours.
Or either you have to lift them off the pavement and toss them int the car. if this is the sign of an IQ then I ask you.
If you want to know my IQ its 173 as measured by mensa.
I have a diploma in computer programming and 5 city & guilds and an hnd in electronics.
also won a free entrance into the london colledge of art years ago but never took it up..

I have to do a project which has to be handed in, in 5 weeks. The project is to test and build a line following robot using a programmable interface chip. Any suggestions on where to find such schematic diagrams would be greatly accepted. It has to be automated so it has to run of batteries. Thanks in advance.
