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.
the function and loop will be
def factorial(x):
total = 1
if x != 1 and x != 0:
for i in range(x,1,-1):
total *= i
return total
Client/server networks require <u>specialized</u> software that enables nodes and the server to collaborate on processing and storage.
A server can be defined as a specialized computer system which is typically designed and configured to store and provide specific remote services for its clients (end users), based on a request.
In Computer and Technology, there are various kinds of server and these include:
In Cloud computing, a client refers to an end user that request for a service over the internet while a server is the specialized computer system which offers this service to a client.
In conclusion, specialized software applications or programs are required for client/server networks, so as to enable nodes and the server collaborate on processing and storage.

Answer:
cables, towers, and underground tubes
Explanation:
Its certainly the above one, and through this internet service is being provided. So internet service is self-understood, and what ISP firstly provides are cables, underground tubes, and the towers. And it is only these all through which the ISP provides internet service. And remember we are in this question dealing with the infrastructure and not the services or products. Hence, phone service, websites, and files, as well as the emails, search engines, and the videos, are not the solution here as they are not the infrastructure. And ISPs never provide the computers, ethernet cables or keyboards.
Hence, the correct answer is as mentioned in the answer section.
