Being extroverted
Problem-Solving
Answer:
Yes
Explanation:
Yes, something approximating a hierarchical file system be simulated. This is done by assigning to each file name the name of the directory it is located in.
For example if the directory is UserStudentsLindaPublic, the name of the file can be UserStudentsLindaPublicFileY.
Also the file name can be assigned to look like the file path in the hierarchical file system. Example is /user/document/filename
The chief ethical concern is "Privacy".
A negative aspect of an enormous number of sources available on internet is the concerns about privacy. Web privacy includes the privilege or command of individual protection concerning the sorting, re-purposing, arrangement to outsiders, and showing of data relating to someone through the Internet.Internet security is a subset of data privacy. Privacy concerns have been enunciated from the beginnings of substantial scale PC sharing.
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.
