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.
Answers:(3) True
(4) Num Lock
Explanations:(3) To undo any task in most of the softwares including Blender, CTRL + Z is used. If you want to double check, go to preference -> Input -> Search for undo. You would see CTRL + Z shortcut there for one time undo (as shown in the picture 1 attached.) Hence (TRUE).
(4) As in blender, during the scene creation, the designers usually use top, left, right or bottom view. Blender has the built-in keys set for those views. As you can see in the second image that the Top view is set to NumPad 7 (likewise others set to other numbers). In order to use the those numpad numbers, you must turn on the NumLock! Hence NumLock is the answer.
I don't know if this is on your list, but I know for a fact that the Nintendo 64 system (or N64) has a 64-bit architecture.
Answer:
The offset
Explanation:
In the question, we understand that the original text is HELLO and the encrypted text is OLSSV.
It should be noted that O replaced H, L replaced E, S replaced L and V replacement O.
This is made possible by a term refered to as offset.
The offset is used to determine the character that will replace another when it is encrypted.
7 characters after H is O; this is same for every other characters in the text.
