Answer:
the atomic radius of a lithium atom is 0.152 nm
Explanation:
Given data in question
structure = BCC
lattice constant (a) = 0.35092 nm
to find out
atomic radius of a lithium atom
solution
we know structure is BCC
for BCC radius formula is /4 × a
here we have known a value so we put a in radius formula
radius = /4 × a
radius = /4 × 0.35092
radius = 0.152 nm
so the atomic radius of a lithium atom is 0.152 nm
Answer:
$39,500
Explanation:
In order to find the total cost, we proceed as follows:
1)
First, the base fee is:
2)
Then we calculate the total number of questions: we have 15 questions per survey, and a total of 500 surveys (for 500 people), therefore the total number of questions is
Since the cost is $5 per question, the total cost of the questions is
3)
Finally, we have 500 persons, and there is a cost of $2 per each person, so the cost due to this is
Therefore, the total cost is:
