Ill choose flowchart. Look picture for the answer
ask me if you have any doubts about my answer.
Answer:
True
Explanation:
Merge & Center is a feature in excel that combines multiple cells and centers the contents of the first cell. You can merge columns and rows too.
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 length of the inclined plane divided by the vertical rise, or you can call it run to rise ratio. The mechanical advantage would increase as the slope of the incline decreases, but problem is that the load will have to go a longer distance. The mechanical advantage would be slope of the incline. I also got confused on a question like this and did some research. Hope this helps!

<u>Networks were originally used as a government weapon 61 years ago</u> to <u>communicate information</u> such as data and research. However, individual networks were eventually discontinued by the government and made open to the public to use for things such as PAN, LAN, MAN, WAN, SAN, and so on.
<u>Our internet today is capable of communicating with bilions of computers.</u> This is possible due to your modem using radio wave-like speeds to connect to your ISP. Your ISP then connects to a larger network, which is connecting to thousands of other networks. You see, <u>the internet is just a large network of networks that are connected through very fast radiowaves</u>. However, it is not just a single network being used anymore; it's thousands of them. The term, "internet" was used to describe this large selection of networks. In short, <u>B</u><u> would be incorrect. </u>
The worldwide web is a protocol used by the internet to connect to select websites favourably from whoever's using it. This obviously would not define the network, as this is something that's used by it. Furthermore, <u>A</u><u> would not be correct.</u>
As described already, the network was a selection of computers used to communicate information to each other. <u>C </u><u>would not be correct </u>as it states that there is only one computer being used.
