Calcium is a nontoxic metal that is used in supplements to maintain strong bones. under high pressure conditions, over about 320,000 atm, it has a simple cubic unit cell. how many atoms of ca are present in each unit cell?

Explanation:

It is known that in a simple cubic unit cell the atoms are only present at the corner of the unit cell. This means that there are in total 8 atoms present in a simple cubic unit cell.

Therefore, in one simple cubic unit cell sharing of one atom is only .

Hence, the total number of atoms in a unit cell will be as follows.

            = 1

Thus, we can conclude that there is 1 calcium atom present in each unit cell.

d.) circle motion requires a force to give it a centripetal acceleration.

it's filtration, but this is an assumption so my apologies if i got this
