(a)
Interpretation:
Atom numbers per unit cell should be calculated.
Concept Introduction:
The atomic symbol of beryllium is Be and has the atomic number of 4. The element Beryllium is a very rare one in the universe. At normal room temperature this element becomes brittle and it is steel gray material. The chemical properties of beryllium arelikethat of aluminum. In the nature it does not occurs as free element.
(b)
Interpretation:
Unit cell packing factor should be calculated.

- Can you solve for V1 and V2arrow_forward(1 point) By dragging statements from the left column to the right column below, give a proof by induction of the following statement: an = = 9" - 1 is a solution to the recurrence relation an = 9an-18 with ao = : 0. The correct proof will use 8 of the statements below. Statements to choose from: Note that a₁ = 9a0 + 8. Now assume that P(n) is true for all n ≥ 0. Your Proof: Put chosen statements in order in this column and press the Submit Answers button. Let P(n) be the predicate, "a = 9″ – 1". απ = 90 − 1 = Note that Let P(n) be the predicate, "an 9" - 1 is a solution to the recurrence relation an = 9an-1 +8 with ao = 0." - Now assume that P(k + 1) is true. Thus P(k) is true for all k. Thus P(k+1) is true. Then ak+1 = 9ak +8, so P(k + 1) is true. = 1 − 1 = 0, as required. Then = 9k — 1. ak Now assume that P(k) is true for an arbitrary integer k ≥ 1. By the recurrence relation, we have ak+1 = ak+1 = = 9ak + 8 = 9(9k − 1) + 8 This simplifies to 9k+19+8 = 9k+1 − 1 Then 9k+1 − 1 = 9(9*…arrow_forwardSolve this problem and show all of the workarrow_forward
