Answer:
11.306 nm/s
or
113.06 atomic layers/sec
Explanation:
Hello!
First we need to know how much an inch equals in nanometers and a day in seconds:
Since <em>1inch = 2.54cm</em> and <em>1cm=10^7nm</em>
<em> </em>1 inch = 2.54 * 10^7 nm<em> </em>
<em />
Also <em>1day = 24hours = 24*60minutes = 24*60*60seconds</em>
<em> </em>1 day = 86.4 * 10^3 s
Therefore the rate at which the hair grows in nanometers per seconds is:
1/26 in/day = (1/26) * (2.54*10^7)/(86.4*10^3) = 11.306 nm/s
Now, if 1 atomic layer = 0.1 nm this means that 1 nm = 10 atomic layers.
Therefore:
The rate in atomic layers is
11.306 nm/s = 11.306 (10 atomic layers)/s = 113.06 atomic layers/sec

If the acceleration is constant, and the starting velocity is zero, the relationship between the acceleration of a falling body (a), the time it takes to fall (t), and instantaneous velocity when it hits the ground (v) is:
the general equation of acceleration is:
vf = vi + at
assuming the initial velocity (vi) is zero, the equation becomes:
vf = at
v = at

<h3><u>Answer;</u></h3>
All types of
Crystals can have <em><u>all types of</u></em> bonds between their atoms.
<h3><u>Explanation</u>;</h3>
- <em><u>Crystals are solid materials which contains atoms, molecules or ions that are arranged in a complex structure forming a crystal lattice.</u></em>
- <u><em>Crystals may have all types of bonds</em></u>, these includes; <em><u>ionic bonds, formed as a result of transfer between a metallic bond and a non-metal atom, Covalent bond, formed as a result of sharing electrons between non metal atoms, hydrogen bonds, metallic bonds Van der Waals bonds, etc.</u></em>
