Answer:
a) Number of atoms per unit cell for Ga = 4 atoms per unit cell
Number of atoms per unit cell for As = 4 atoms per unit cell
b) Volume density of Germanium in its unit cell = 4.35 × 10²² /cm³
Explanation:
GaAs has a number density of 4.42 x 10²² atoms/cm³ from literature.
Since GaAs is known to contain almost equal amounts of Ga and As.
Number density of Ga = Number density of As = 2.21 × 10²² atoms/cm³
Number density = Number of atoms in a unit cell/volume of the unit cell
Number of atoms in the unit cell = ?
Volume of the unit cell = (lattice parameter)³ = (5.65 × 10⁻⁸)³ = 1.804 × 10⁻²² cm³
Number of atoms per unit cell for Ga and As = number density × volume of unit cell = 2.21 × 10²² × 1.804 × 10⁻²² = 4 atoms/unit cell
b) Volume density = Number of atoms per unit cell/volume of unit cell
Germanium has 8 atoms per unit cell (from literature),
Volume of unit cell = (lattice parameter)³ = (5.65 × 10⁻⁸)³ = 1.804 × 10⁻²² cm³
Volume density = 8/(1.804 × 10⁻²²) = 4.35 × 10²² /cm³
Hope this helps!

Explanation:
Using a process of informed decision-making, the designer or design team compares different solutions to the requirements of the problem and either chooses
Answer:
Energy Saved = 6.93 x 10⁹ Btu
Cost Saved = $ 30145.5
Explanation:
The energy generated by each boiler can be given by the following formula:
Now, the energy saved by the increase of efficiency through tuning will be the difference between the energy produced before and after tuning:
<u>Energy Saved = 6.93 x 10⁹ Btu</u>
Now, for the saved cost:
<u>Cost Saved = $ 30145.5</u>
Answer:
Civil engineers in academic are involved with teaching the next generation of engineers and developing engineering curriculum that prepares students with the knowledge they need to succeed in their careers. This career path requires an advanced degree, including a doctorate in most cases.
