Answer:

b. size

Explanation:

We can use the size() method of java.util.ArrayList to determine the size of an  ArrayList in Java. The size() method of the ArrayList class returns an integer which is equal to the number of elements present in the ArrayList.

Below is an example code to illustrate the use of the size() method of the ArrayList:-

     ArrayList<Integer> aList = new ArrayList<Integer>(5);

      aList.add(25);

     aList.add(2);

     aList.add(5);

     aList.add(22);

     System.out.println("Size of the array list: " + aList.size());

This will print the size of the array list as 4 since we've added four numbers into the array list.

Mila [183]

Solution:

It is done by Native Os X command line tool that can do this.

Active Directory, the data store contains database files and processes that store and manage directory information for users, services, and applications. A copy of the data store runs on each domain controller in the forest. The Active Directory data store is often referred to as the directory.

The ideal environment for the data store includes the following:

A domain controller running an operating system in the Windows Server 2003 family and containing hardware that meets the minimum hardware requirements of the edition of the operating system (Windows Server 2003, Standard Edition; Windows Server 2003, Enterprise Edition; or Windows Server 2003, Datacenter Edition)

For environments consisting of multiple domain controllers, the presence of a fully functioning Active Directory replication topology

For environments consisting of multiple domain controllers, the presence of a fully functioning File Replication Service (FRS) topology

A regular backup schedule

Regular monitoring of Active Directory, either through manual review of event logs or through an automated monitoring solution, such as Microsoft Operations Manager (MOM)

This is the required description describes the elements of the Active Directory data store, including its architecture, protocols, interfaces, logical structure, physical structure, processes and interactions, and network ports.

A. Calculate the diffusion coefficient for magnesium in aluminum at 450°C.
SIZIF [17.4K]

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.
