The answer is DNS
(Domain Name System)
IP addresses are difficult to remember and therefore, the internet
allows you to specify a computer using a host name. The same case happens to
DNS. It maps domain names to IP addresses. Domain names are alphabetic making them easier to remember.
Answer:
I'm pretty sure to get the absolute maximum amount the EFC has to be 0 or really close to it. The EFC, or Expected Family Contribution, is mainly determined by your family's income. If your family has multiple students who will be enrolled in college, the number may be lower. It's not really about what number a student "should" have though, because the only way for you to lower it yourself is to lie, and you really don't want to do that-if you are found to have lied on your FAFSA there can be some serious legal consequences.
Answer:
Telepresence refers to a set of technologies which allow a person to feel as if they were present, to give the appearance that they were present, or to have an effect, at a location other than their true location. Teleoperation is the operation of a machine at a distance.
Explanation:
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.
