Answer:

A.piston ring

Explanation:

A piston ring is a round component that is located between the piston and the cylinder and it helps to prevent that the combustion gas leaks through the opening between the piston and the cylinder and this allows the engine to work efficiently. Because of this, the engine component that forms a tight seal between the piston and the cylinder and is necessary for proper engine operation is the piston ring.

According to Amdahl's Law, what is the speedup gain for an application that is 60% parallel and we run it on a machine with 4 pr
rodikova [14]

With four processing cores, we get a speedup of 1.82 times.

<h3>What is Amdahl's Law?</h3>

Amdahl's law exists as a formula that provides the theoretical speedup in latency of the implementation of a task at a fixed workload that can be expected of a system whose resources exist improved.

Amdahl's law exists that, in a program with parallel processing, a relatively few instructions that hold to be completed in sequence will have a limiting factor on program speedup such that adding more processors may not complete the program run faster.

Amdahl's law stands also known as Amdahl's argument. It is utilized to find the maximum expected progress to an overall system when only part of the system exists improved. It is often utilized in parallel computing to indicate the theoretical maximum speed up utilizing multiple processors.

Hence,  With four processing cores, we get a speedup of 1.82 times.

Create a program that contains 4 methods / functions... main(), getTestScores(), calcAverage(), and displayAverage(). The main()
jeyben [28]

Answer:

import java.util.Scanner;

public class  num6{

   static int getTestScores(){

       System.out.println("Enter the Score");

       Scanner in = new Scanner(System.in);

       int score = in.nextInt();

       return score;

   }

   static double calcAverage(int score1, int score2, int score3){

       return (score1+score2+score3)/3;

   }

   static void displayAverage(double ave){

       System.out.println("The Average is "+ave);

   }

   public static void main(String[] args) {

       int num1 = getTestScores();

       int num2 = getTestScores();

       int num3 = getTestScores();

       //Calling Calculate Average

       double average = calcAverage(num1,num2,num3);

       //Calling displayAverage

       displayAverage(average);

   }

}

Explanation:

  • Using Java programming Language
  • Create the four methods
  • getTestScores() Uses the Scanner Class to receive an in variable and return it
  • calcAverage() accepts three ints as parameter calculates their average and return it
  • displayAverage() Accepts a double and prints it out with a concatenated string as message
  • In the Main Method, getTestScores is called three times to obtain three numbers from the user
  • calAverage is called and handed the three numbers
  • printAverage is called to output the calculated average
