Answer:

A) Technician A only.

Explanation:

Only Technician A who said that Positive Temperature Coefficient (PTC ) heaters can be built into a conventional heater core assembly is correct because they use the same heat loss and transfer system. This is easily verifiable with a simulation.

Technician B, who said that a PTC heater's electrical resistance will decrease as its temperature increases is incorrect because the resistance of a conductor is directly proportional to temperature. This means that a PTC heater's electrical resistance will increase as its temperature increases.

Which three options below describe typographic hierarchy?
Korvikt [17]

The three options that describe the typographic hierarchy are given below:

  • The importance of information is shown through the text.
  • The presentation of the text in terms of structure.
  • The placement of the text defines its flow and hierarchy.

Thus, the correct options are A, B, and C.

<h3>What is Typographic hierarchy?</h3>

Typographic hierarchy may be characterized as an approach that utilizes typography: the size, font, and layout of distinct text components to produce a hierarchical division that can authenticate users where to look for specific information.

The purpose of using this methodology is to focus on the main points of the article accordingly. It increases the sense of understanding of the readers with focus.

Therefore, it is well described above.

Polymorphism means (Points : 2) many forms
Pavel [41]

Answer:

many forms

Explanation:

Polymorphism is a construct in object oriented programming which means multiple forms.For example: Suppose I have a function which performs the add operation on two integers and another function with the same name which concatenates 2 given strings:

  • int add ( int a, int b);
  • string add ( string a , string b)

The two functions represent polymorphic forms of the add function. The function to be invoked at runtime is determined by the runtime argument type.

For example , add (2,3) will invoke int add ( int a, int b);

Similarly, add("hello","world") will invoke string add ( string a , string b);

Write a method that prints on the screen a message stating whether 2 circles touch each other, do not touch each other or inters
beks73 [17]

Answer:

The method is as follows:

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

    double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

    if(d == r1 + r2){

        System.out.print("The circles touch each other");     }

    else if(d > r1 + r2){

        System.out.print("The circles do not touch each other");     }

    else{

        System.out.print("The circles intersect");     }

}

Explanation:

This defines the method

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

This calculate the distance

    double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

If the distance equals the sum of both radii, then the circles touch one another

<em>     if(d == r1 + r2){</em>

<em>         System.out.print("The circles touch each other");     }</em>

If the distance is greater than the sum of both radii, then the circles do not touch one another

<em>    else if(d > r1 + r2){</em>

<em>         System.out.print("The circles do not touch each other");     }</em>

If the distance is less than the sum of both radii, then the circles intersect

<em>    else{</em>

<em>         System.out.print("The circles intersect");     }</em>

}
