Answer:
short-term
7
Explanation:
Short-term memory is the capacity for holding, but not manipulating, a small amount of information in mind in an active, readily available state for a short period of time.
The human brain can only hold about seven pieces of information for less than 30 seconds.
As an example:
Tommy is repeating a series of digits in the order in which he heard an experimenter read them. The experimenter is testing the capacity of Tommy's short term memory. Tommy should be able to repeat about 7 digits correctly.

Which is a net ionic equation for the neutralization of a weak acid with a strong base?
Answer: A net ionic equation for the neutralization of a weak acid with a strong base is:
Explanation:
- Let´s consider this balanced molecular equation:
HCN(aq) + NaOH(aq) --------} NaCN(aq) + H2O(l)
- You can see it is an acid-base reaction because OH (-) is taking away the H from HCN.
Where: NaOH(aq) is the base and
HCN(aq) is a weak acid as it has no oxygen.
- For the total ionic equation we will break up all the possible break ups and we get:
HCN(aq) + Na (+)(aq)+ OH(-) (aq) --------- } Na (+)(aq)+CN(-) (aq) + H2O(l)
- For the net ionic equation we reduce:
HCN(aq) + OH(-)(aq) -------- } CN(-)(aq) + H2O(l)
- We get the weak acid HCN(aq) plus the hidroxide ion which is the base.
The spectator ions is Na(+)
The net ionic equation for the reaction of any strong acid with any strong base is identical
Net ionic equations for acid-base reactions a neutralization reaction between a weak acid, HCN, and a strong base, KOH.
A weak acid, weak base reaction can be shown by the net ionic equation example:
HCl(aq) + NaOH(aq) ↔ H2O(l) + NaCl(aq) HF(aq) + OH-(aq) ↔ H2O(l) + F-(aq) HF(aq) + NaOH(aq) ↔ H2O(l) + NaF(aq) H3O+(aq) + OH-(aq) ↔ 2 H2O(l)
When a strong acid neutralizes a weak base, the resulting solution's pH will be less than 7.
Weak acids as hydrofluoric, HF only dissociate partially or will react with sodium hydroxide, NaOH , a strong base, to produce aqueous sodium fluoride, NaF , and water to get the net ionic equation that describes this neutralization reaction.
They are not considered to split apart into ions when writing net ionic equations.
This reaction is considered a neutralization reaction. The base (NaOH) and weak acid (CH3COOH) react to produce a salt (NaNO3 and water (H2O).

Passing by reference is used if a parameter's data flow is A. one-way, into the function. B. one-way, out of the function. C. two-way, into and out of the function. D. a and b above E. b and c above
Passing by reference is used if a parameter's data flow is two-way, into and out of the function.
C. two-way, into and out of the function.
Explanation:
If a function in programming language passing the parameter by reference means it only sending the address of parameter to a function. If any value is changed on reference parameter it will changed original value.
If parameter passed by value means it is one way, where value been send to the function.
Whereas by reference means it two-way, in and out of the function. Mostly it called as pointer.
It is available in c , c++, where declare of variable “*” or “&” address off.

Explanation:
Assume the existence of a BankAccount class. Define a derived class, SavingsAccount that contains two instance variables: the first a double, named interestRate, and the second an integer named interestType. The value of the interestType variable can be 1 for simple interest and 2 for compound interest. There is also a constructor that accepts two parameters: a double that is used to initialize the interestRate variable, and a string that you may assume will contain either "Simple", or "Compound", and which should be used to initialize the interestType variable appropriately. There should also be a pair of functions getInterestRate and getInterestType that return the values of the corresponding data members (as double and int respectively).
Answer:
Class SavingsAccount : public BankAccount
{
double interestRate;
int interestType;
public SavingsAccount(double interestRate, string interestType)
{
this.interestRate=interestRate;
if(interestType=="Simple")
this.interestType=1;
else if(interestType=="Compound")

Explanation:
Technician A says that replacement pistons can be of different weights from the original pistons. Technician B says that some engines use an offset piston pin to help reduce piston slap when the engine is cold. Who is right?
A) Technician A only
B) Technician B onlyC) Both technicians A and B
D) Neither technician A nor B
Answer:
B) Technician B only
Explanation:
Slap is caused when engine is cold
Piston slap is moves ups and down in the engine block.Air and fuel explodes inside the chamber.Piston is connected to pin.
The Piston can be sufficiently enormous with the goal that the cylinder rocks starting with one side then onto the next to cause the cylinder slap. Aluminum squares will in general effectively capitulate to this issue than others.
Piston that experience increasingly chilly leeway acquire speed when the cylinder moves from the minor to significant push side and this causes the cylinder slap.
Final answer:
Both technicians A and B are correct. Technician A notes that replacement pistons can differ in weight from originals, while Technician B explains that offset piston pins reduce piston slap in cold engines.
Explanation:
The question at hand deals with nuances in engine design and piston assembly. Technician A states that replacement pistons can differ in weight from the original pistons. This is correct because replacement pistons, especially performance types or those made by different manufacturers, can have different weights due to material differences or design. Technician B discusses the use of an offset piston pin, which is a design feature indeed used in some engines to mitigate piston slap during cold start conditions. The offset position changes the thrust angle during the piston's travel, thereby reducing the noise and potential wear associated with piston slap. Hence, the correct answer is C) Both technicians A and B are right.

you work in the Human Resources department of a company that has partnered with a similar company in Brazil on a big contract. you have been asked to create a visual that will help the sales team understand who their counterparts are in the Brazilian company. what should you create?a. flowchartb. mapc. tabled. organizational chart
Answer:
Option C: Organizational Chart.
Explanation:
The main goal, in this case, it's to help the team to know the company and its integrants.
An organizational chart -- also called organigram -- is the best tool to clarify how the Brazilian company works.
The organigram is a diagram that illustrates the structure of an organization, how one part its related to another, and the assigned responsibilities of each specific department. Through this tool, the team will have a clear idea of who their counterparts are and how their job is related to ours.
Final answer:
To help the sales team understand their counterparts in the Brazilian company, you should create an organizational chart. This visual tool will detail the company's structure, roles, and lines of communication, which is vital for building working relationships and setting clear goals for the team.
Explanation:
To help the sales team understand who their counterparts are in the Brazilian company, you should create an organizational chart. An organizational chart will display the company structure and detail the roles of each team member, making it easier for your sales team to identify and understand their counterparts. It shows who does what, where each person fits into the organization, and who reports to whom, thus clarifying lines of communication and authority. This will be extremely beneficial for forging effective working relationships with the Brazilian team.
When creating an organizational chart, consider including not only the names and titles of the counterparts but also a brief description of their roles and responsibilities. This can help your sales team to learn about the type of work others do and how it relates to what they do. It's worth noting that organizational structures have become more flattened in recent years, so forming collegial relationships with all levels of staff is encouraged. Developing such a chart will also assist in maximizing the first year on the job by setting clear goals and milestones for your team.
Your current backup schedule involves differential backups of all data Monday through Saturday, with a full backup on Sunday. Last Saturday, one of your storage drives failed prior to running the daily backup. What must be done to recover the data on the failed drive?
Answer:
restore the last full backup first.
Explanation:
Based on the information provided within the question it can be said that what you should do is restore the last full backup first. This is because a differential backup, backs up all the progressive changes made after the last full backup. Therefore the last full backup would contain all the data before the drive failed. Once this is done then you may restore the last successful differential backup prior to the drive failure.

Static packet-filteringB. Application-level gatewayC. Stateful inspectionD. Circuit-level gateway
The relationship between current packets with the previous packets of the same session, Stateful inspection firewalls are able to grant a broader range of access for authorized users and activities and actively watch for and block unauthorized users and activities.
C. Stateful inspection
Explanation:
Basically packet filtering handles in gateways level at firewall. As Network administrator he or she keep monitoring the network packet, if any unauthorized user login is found on any session or same session it is consider as high risk.
These shows some illegal access to computer has be executed as immediate action network engineer has to see logs and their activities in firewall either if it invalid transaction immediately he has put filter of ip address or mac address possible.
Network administration he or she update firewall patches at regular intervals.
NOTE: in mathematics, the square root of a negative number is not real; in Java therefore, passing such a value to the square root function returns a value known as NaN (not-a-number). Given a double variable named areaOfSquare write the necessary code to read in a value, the area of some square, into areaOfSquare and print out the length of the side of that square. HOWEVER: if any value read in is not valid input, just print the message "INVALID". ASSUME the availability of a variable, stdin, that references a Scanner object associated with standard input.
import java.util.Scanner;
class square_root
{
public static void main (String[] args)
{
Scanner s=new Scanner(System.in);
System.out.print("Enter the area: ");
double areaOfSquare=s.nextDouble();
if(areaOfSquare<0)
{
System.out.println("INVALID");
System.exit(2);
}
System.out.println("The side of the square is: "
+Math.sqrt(areaOfSquare));
}
}
Answer:
import java.util.Scanner;
class square_root
{
public static void main (String[] args)
{
Scanner s=new Scanner(System.in);
System.out.print("Enter the area: ");
double areaOfSquare=s.nextDouble();
if(areaOfSquare<0)
{
System.out.println("INVALID");
System.exit(2);
}
System.out.println("The side of the square is: "
+Math.sqrt(areaOfSquare));
}
}
Explanation:
To read the area of a square and compute its side length in Ja-va, check for negative inputs and handle them by printing "INVALID". For valid inputs, compute the square root and print the result.
To solve the problem of reading the area of a square and printing the side length, follow the steps below:
Read the input value for the area of the square.Check if the input value is negative. If it is, print "INVALID".If the value is valid (non-negative), compute the square root and print the side length.Here is the updated code:
import ja-va.util.Scanner;Write a class definition of a class named Value with the following: a boolean instance variable named modified, initialized to false an int instance variable named val a constructor accepting a single parameter whose value is assigned to the instance variable val a method getVal that returns the current value of the instance variable val a method setVal that accepts a single parameter, assigns its value to val, and sets the modified instance variable to true a boolean method, wasModified that returns true if setVal was ever called.
Answer:
The class definition to this question can be given as:
Class definition:
public class Value //define class value.
{
private boolean modified = false; //define variable modified.
private int val; //define variable.
Value(int i) //parameterized constructor
{
val = i; //holds parameter value.
}
public int getVal() //define method getVal.
{
return val;
}
public void setVal(int i) //define method setVal
{
val = i; //holds parameter value
modified = true; //change boolean variable value.
}
public boolean wasModified() //define method wasModified.
{
return modified; //return value.
}
}
Explanation:
The description of the above class definition as follows:
Firstly we define a class that is "value" inside a class we define two variable that is "modified and val". Where modified is a boolean variable that holds boolean value true or false and val is an integer variable that holds an integer value. Inside the class, we define parameterized constructor in this constructor we pass an integer parameter that is "i" inside this constructor we use the val variable for hold i variable value. Then we define three functions that are "getVal, setVal, and wasModified". The getVal() function is used for return value. The setVal() function uses an integer parameter that is "i" this function holds value in variable i in val variable and change value of the modified variable that is "true". The wasModified() function is used to return modified variable value.After Maya gave her friend the password to a protected website, the friend was able to remember it only long enough to type it into the password box.
