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.
I wouldn't think so unless they have access to your phone or account. But I don't believe this is school related.

Answer:
filler content
Explanation:
Isabel must use some sort of filler content while creating a wireframe that she is up with. For the banner, she can make use of the placeholder, and for the text, she can make use of the lorem ipsum. Also, if the wireframe is low fidelity then only she can use above. And if the wireframe is high fidelity then she should use the original banner and text.
Answer:
printArray(inventory, n);
Explanation:
The question doesn't specify in which language this has to be done, here's a generic call then... so if it's aimed at a specific language, some minor adjustments might be needed to respect the proper syntax/structure of that specific language.
Given:
printArray: function name, using 2 parameters.
inventory: array of ints
n : integer, number of items in array inventory
The call to the function would be:
printArray(inventory, n);
