Acubic crystal structure has only 3 atoms fully belong to its unit cell. if the radius of the atom is 0.314 of the unit cells size (e. g.r=0.314a) calculate the atomic packing factor. remember apf=(volume of atoms belonging to the unit cell)/volume of the unit cell. also remember, volume of the cube is a^3 where a=side of the unit cell and the volume of one atom = (4/3)*3.14*r^3

x+2 because it just doubles hon so the pattern can actually tell you the expression.

so for example,

if x=2 then 2+2 is 4

if x=4 then 4+4 is 8

and so on and so forth.

i really hope that this makes sense and you out in a way hon: )

do you have any options?

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
