Answer:

C

Explanation:

C is the correct answer. When we have model A (for example) it could have 3 things from the most recent experiment. however, if another experiment is done, a new model must be made because we now do not have 3, but have 4 things that the model must show. from what we see, the <em>said</em> most recent model is not showing this. that is why it needs to be updated, because new discoveries makes the current model inaccurate.

C.) New discoveries make the current model inaccurate. Since science is all about observation and experimentation, it is logical that whenever new findings are gathered, scientific models must be modified to adapt to the information. As new ideas and concepts are uncovered, models should be updated to make them correct.

Answer:

The best choice is 802.11a.

Explanation:

The most common option, that is widely used in home internet is 802.11b, however, this only supports a max speed of 11Mbps.

802.11a supports up to 54Mbps and it has regulated frequencies that prevent interference from other devices, such as the wireless system that your client already has. This option is more expensive, and its signal has issues going through walls and rooms but still, it is the one that fits him the most.

kompoz [17]

Answer:

The code will give an error that is "At least one public class is required in main file".

Explanation:

In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:

Program:

import java.util.HashSet; //import package

public class A  //define class as public.

{

   public static void main(String[ ] args) //define main method.

   {

       HashSet set = new HashSet(); //creating hashset object.

       set.add("A"); //add alphabet in hashset

       set.add("B"); //add alphabet in hashset

       set.add("C"); //add alphabet in hashset

       System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.

   }

}

Output:

Size of HashSet is : 3

Explanation of the program:  

  • In the above program, we define a public class that is "A" and inside the class, we define the main method.  
  • Inside the main method, we create a HashSet class object that is "set".  
  • To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.
