Step-by-step explanation:

(5-2)^2+(5-2)^2=

we know that
The radius of the hydrogen atom is 
The radius of the nucleus is
m
the ratio is equal to

that means the radius of the hydrogen atom is 44,083.33 times the radius of the nucleus
therefore
<u>the answer is</u>
the ratio is equal to 44,083.33
In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
BB' = 6
B'A = 2
Step 02:
scale factor:

The answer is:
scale factor = 3
Answer:
27:9 3:1.................
9514 1404 393
Answer:
100°
Step-by-step explanation:
Angle AKC is a vertical angle with angle BKD, so has the same measure. Since K is the center of the circle, arc AC has the same measure as angle AKC: 100°.
