Answer:
a) D = 4.88 * 10^(-14) m^2 / s
b) <em>t </em>= 1.1 hr
Solution:
a) Magnesium in Aluminum diffusion:
D = Do * exp(-Qd / RT)
= (1.2 * 10^(-4) m^2 / s) * exp ( - 130,000 / 8.31 * 723.15)
= 4.88 * 10^(-14) m^2 / s
D = 4.88 * 10^(-14) m^2 / s
b) The composition remains same at say the distance Xo:
(Cx - Co) / (Cs - Co) = Constant
Xo^2 / D_{550} * <em>t </em>= Xo^2 / D_{450} * 15
D_{550} * <em>t </em>= D_{450} * 15
(1.2 * 10^(-4) m^2 / s) * exp ( - 130,000 / 8.31 * 723.15) * <em>t</em>
(4.88 * 10^(-14) m^2 / s) * 15
by, solving for <em>t </em>we get:
<em>t </em>= 1.1 hr
So, the time required is 1.1 hr.
Answer:
This is true but an Engineer is much more than that. They are the professionals of engineering, who do the invention, analyze, design and test complex systems, machines, structures, machines for fulfilling the functional objectives gadgets as well as the requirements while taking into consideration the limitations that come up due to practicality, safety, regulations, and cost.

Answer:
The right approach is Option b (volume testing).
Explanation:
- A non-functional trial that has been conducted throughout a results evaluation where even a large amount of information becomes accessible to something like the program, would be determined as Volume testing.
- The application functionality has been analyzed by determining the maximum volume throughout the database.
Other options are not related to the given query. So the above is the right response.
