Has anyone ever figured out how fast we are moving when we are sitting still?

What I mean is has anyone ever combined the speeds that we are moving at when we are sitting still?
First, there is the rotation of Earth on its axis.
Second, there is the Earth's orbit around the sun.
Then there is the solar system's speed through the Milky Way.
And finally, there is the galaxy moving relative to the rest of the universe (assuming that the Big Bang theory is correct).

I know that this is a strictly academic problem, but I would appreciate some conjecture.

Chemistry Help...?

HCl and NH3 react to form NH4Cl, a white solid. If NH3 and HCL are introduced at opposite ends of a 60.0cm tube, how far from the HCl end will the white ring of NH4Cl form?

The answer is 24.3cm but I have no clue on how to solve thing. Can someone please explain it to me. Thanks.

What type of structure and close-packed structure does PbF2 have?

I have home-exam in chemistry and I need some help. Why is PbF2 a good anion conductor? What kind of close-packed structure (hexagonal or cubic?) and what type and number of holes occupied? Give one example of doping this structure to make it a better ion conductor by increasing the number of anion vacancies in the system? I hope someone can help me or maybe give me some advise on where to find this information.

physics help needed right now thanks?

1. an astronaut lands on a planet that has twice the diameter and mass of earth. how does the astronaut weight differ from that of earth.

2.if the earth were uniform density [same mass and volumes throughout ] what would the value of g be inside the earth at half its radius.

3.the mass of a certain neutron stae is 3.0 x 10^30 kg [1.5 solar masses] and its radius is 8000 m [8 km]. what is the acceleratiin of gravity at the surface of this burnt out condensed star

Why are you cold when you get out of the pool?

Please answer this question using chemistry terms such as: specific heat, intermolecular forces, evaporation, etc.

-------------------

It is summertime, and you are in the pool. The air is much warmer than the pool water, but when you get out of the water into the warmer air, you feel cold! Explain why you feel cold, even though the air around you is warmer than the pool water you just got out of.

Thanks for your help.

Help with superposition circuit analysis!?

http://i143.photobucket.com/albums/r147/rAOL87/Circuit3.jpg

The circuit above is the circuit I must analyze. I've been told that the current that runs through the points Va and Vb is zero because of the symmetry. I need to find the individual currents and voltages that run through each resistor, and I was wondering how I go about this with superposition?
