The crystal structure of an ionic compound consists of alternating cations and anions lying next to each other in three dimensions. If the cation radius is 55.9% of the anion radius and the distance between the cation nuclei is 580. pm, what are the radii of the two ions? (Note: This ionic compound is a three dimensional array. The cation to cation, center-to-center distance specified is through the center of the anion.)
anion
pm

cation
pm

Will give 10 points to right answer

I'm sure that there's a scientific explanation for ghost sitings and that it's not supernatural. I think that they are holograms from a civilization sent out millions of years ago using some kind of device that projects photons at the speed of light!

Found it while we were camping and I need to know what animal it is. We guessed sheep but we're not quite sure. Does anyone know exactly (and any websites that kind of prove it would be nice)?

I found a beautiful little ladybug in my house this morning. Obviously, it really belongs outside. However, the daytime temps around here (Westchester, NY) are in the low 60's and we have been getting some frost at night.
If I put the ladybug out during the day, will it find someplace warm to hide at night, or do they just die at this time of year?
Thank you.

The story is:
Every 26000 years the earth is tilted to a degree where the sun goes all whack and stuff its alinement is so rare that once every 26000 years everything will tip over if i may!
Like say all the volcanoes will erupt and all the oceans will overflow or spill out!
There will be a world wide thing and its happening in 5 years we can do anything to stop it!
We will live through it but we will be like pilgrims or something no more t.v computer( jobs actors singers etc) cars it will all be wiped out!
So its happening at december 21 2012 so heres my question
do you think its going to be another Y2K (which i never believed) or something more and they have proof the mayan and chinese calendars even said so so what do you think?

What does these mean? All of them correspond to the 4 basic laws of thermodynamics and I'm not quite sure of their meanings.

Zeroth Law: You have to play the game
First Law: You can’t win
Second Law: You can’t break even, except on a very cold day   
Third Law: It doesn’t get that cold.

I need answers. Thanks a bunch!
