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:
The answer is "Fiber Optic Cable".
Explanation:
In the given question options are defined, but in these options, there is some error.
The optical fiber cable is also known as internet wiring, which includes fiber strands inside an isolated housing. It is used to transferring data at a very high speed. This cable is developed for long-range data networking, high-performance connectivity, and multimedia, and other choices are wrong that can be described as follows:
- A modem is used to transmits data over a network, that's why it is wrong.
- Router is used to transport traffic between your computer and the internet, that's why it is wrong.
