I do not understand why a face centered cubic has an a= 4r/sqrt2 and why a body centered cubic has an a of 4r/sqrt3. I know it is geometric, but I have not taken math in a very long time, and need it explained fairly simply, if possible.

An ionic molecular solid AX has a molecular weight 250 g/mol is face centered cubic with regard to the anions, X, which have a radius of 300 pm. The cations, A+, have radius 200 pm and are found octahedral interstitial spaces. The edge of each unit cell is as long as the diameter of 1 cation and 1 anion. When 25 grams of AX (as described above) is dissolved into 500 grams of water at 293.15 K 41.36 kJ of...

I have personally never done this. I don't understand why so many sites do, if you do your development on a development server why would you ever need to shut down your production site? I have always wondered about this. What are they doing during this time, what requires doing this?

Please help me I do not understand. Thank you! Evolution has produced interesting scaling relationships between energy use and body size. Why was it predicted that the scaling relationship of metabolic rate to body size is 2/3? Why is the scaling relationship closer to 3/4? Prove that you have a critical understanding of the metabolic theory of ecology.

I don't understand the part whether to ACCEPT or
REJECT a project please explain.
Do I always have to reject a project when NPV is
NEGATIVE? Kindly explain base on the attached photo here or if
there's simplest way for me to understand.
How do I know a benchmark of this given questions?
I know how to calculate them so I've done the workings
already. I just need explanation Why must reject and accept.
