The correct answer is B, a laminated core and a shading coil.

A key difference in an AC relay is the presence of a "shading coil". The purpose of this coil is to keep the relay on when the current drops to zero during phase change (note that in AC power the current and voltage are alternating in a sine wave around 50/60 times per second). The shading coil retains some magnetic energy and essentially holds the relay ON when the current drops to zero momentarily due to the AC waveform.

AC relays also have a laminated core to prevent losses due to eddy current heating.

Answer: review; quality

Explanation:

SQA refers to the ongoing process that can be found in the Software Development Life Cycle whereby the developed software is checked in order to ensure that the desired quality measures are met. The SQA processes is vital as it checks for the quality in every development phase.

The first step of the SQA process is to (review) the software development process. The next step is to set (quality) attributes.

Technology can cause a drop in input costs.<br> a. True<br> b. False
Marizza181 [45]
<span>True that technology can cause a drop in input cost. In a production process, there are three kinds of cost that called input cost, which are the direct material cost, direct labor cost, and overhead cost. Technology usage can make the production process more efficient by reducing labors included in the process. This condition leads to a cost reduction.</span>

Write a public member function which replace that replaces one occurrence of a given item in the ArrayBag with another passed as
ira [324]

Answer:

The method is written in Java

public static boolean abc(int [] ArrayBag,int num, int replace){

    Boolean done = false;

    for(int i =0; i<ArrayBag.length;i++){

        if(ArrayBag[i] == num){

            ArrayBag[i] = replace;

            done = true;

        }

    }

    for(int i = 0;i<ArrayBag.length;i++){

        System.out.println(ArrayBag[i]+" ");

    }

    return done;

}

Explanation:

The method is written in java

The arguments of the method are:

<em>1. ArrayBag -> The array declares as integer</em>

<em>2. num -> The array element to check the presence</em>

<em>3. replace - > The replacement variable</em>

This line defines the method as boolean.

public static boolean abc(int [] ArrayBag,int num, int replace){

This line declares a boolean variable as false

    Boolean done = false;

The following iterates through the elements of the array

    for(int i =0; i<ArrayBag.length;i++){

This checks if the array element exist

        if(ArrayBag[i] == num){

If yes, the array element is replaced

            ArrayBag[i] = replace;

The boolean variable is updated from false to true

            done = true;

        }

    }

The following iteration prints the elements of the array

<em>     for(int i = 0;i<ArrayBag.length;i++){</em>

<em>         System.out.println(ArrayBag[i]+" ");</em>

<em>     }</em>

This prints returns the boolean thats indicates if replacement was done or not.

    return done;

}

<em>Attached to this solution is the program source file that includes the main method of the program</em>

Trying to make the baseplate red and turn off can collide then the game waits 5 seconds and turns on can collide, making the bas
kenny6666 [7]

Answer:

Explanation:

yes

but dont forget to call makeBasePlateGreen

maybe you would call it at the end of the program?

by the way you have a typo at the end

make the O lowercase

myBlasePlate.BrickColor = BrickColor.Green()

and then add this to the end

makeBasePlateGreen()

so you call the function and actually use it.
