Which type of microscope can only be used to view non-living specimens?

Computers and Technology

Fynjy0 [20]3 years ago
5 0

Answer is D: Electronic microscope

An electronic microscope has greater resolving power and much higher magnifications. Most high-resolution electron microscope cannot be used to image living cells because the particle beam of powerful electrons used to illuminate a specimen also destroys the samples. Engineers, however, are coming up with ways to overcome this critical limitation by using quantum mechanical measurement. Quantum mechanical measurement will help avoid damage to the specimen by sensing objects remotely without ever hitting the imaged object.

natali 33 [55]

Radio buttons exist like selection lists in which they limit fields to a set of potential values; but, unlike selection lists, the options appear as respective controls in the web form.

<h3>What is Radio button?</h3>

A radio button or option button exists as a graphical control element that permits the user to select only one of a predefined set of mutually exclusive options. The singular property of a radio button causes it distinct from checkboxes, where the user can select and unselect any numeral of items.

Radio buttons exist as a common way to permit users to make a single selection from a list of options. Since only one radio button can be selected at a period (within the same group), each available option must be its item and label. Radio buttons exist like selection lists in which they limit fields to a set of potential values; but, unlike selection lists, the options appear as respective controls in the web form.

The Java compiler does not check for an ArrayIndexOutorBoundsException during the compilation of a program containing arrays. O
yulyashka [42]

Answer:

TRUE

Explanation:

  • Let us first understand what is an ArrayIndexOutOfBounds Exception.
  • As the name itself suggests the index for the array has gone out of bound (permissible value) and an exception (anamoly) is resulted.
  • So, it throws an error.
  • That means if an array, Employee of size n is defined then the permissible elements are Employee[0] to Employee[n-1]. If any negative index or with the index is greater than n-1 is tried to access it throws an error saying ArrayIndexOutOfBounds Exception.
  • In java, during the compilation of the program the compiler doesn't check for the ArrayIndexOutOfBounds Exception.It checks during running the program.
  • So, it is called a Runtime Exception.

If we were to replicate Dr. Stanley Milgram's obedience study today, do you think the results would be different?
Montano1993 [528]

Answer:

Explanation:

The results would be exactly the same. We have learned little about authority and when to oppose it.

I'll give you an example. Last night I was in a restaurant like Taco Bell or Subway. Across from me was a girl with an ordinary backpack which was all I could see. It was quite common to see that in the University District where I was. I paid no attention until two policemen came in (both over 200 pounds -- she was tall but could not have been more than 130) and began arrest procedures. She started shouting very foul language but otherwise did not resist. They put handcuffs on her wrists which were behind her back. Again she she  used profane language only screaming that they were hurting her. It took the one police officers a moment to find his key and loosen the cuffs, which he did, but she was still uncomfortable and cursing.  

She was silent as they took her out. Nobody questioned the incident at all. Do you think Dr. Millgram would recognize this as an example of his theory? I'm sure he would. Trust me, this was not staged. There was a 3rd officer who drove the girl and one of the 2 arresting officers away.

Create a Boolean function odd_number_digits(n) that returns True when a positive integer has an odd number of digits. (You may a
Snowcat [4.5K]

Answer:

Following are the code to this question:

import java.util.*;//import package for user input

public class Main//defining class main

{

   public static boolean odd_number_digits(int n)//defining boolean method odd_number_digits

   {

       if(n>0 && n%2!=0)//defining if block that check value is positive and odd number

       {

       return true;//return value true

       }

       else//defining else block

       {

           return false;//return false value

       }

   }

   public static void  sum_odd_digits(int n)//defining a method sum_odd_digits

   {

       int sum=0,i;//defining integer variable

       for(i=0;i<=n;i++)//defining for loop

       {

           if(i%2!=0)//defining if block for odd number

           {

               sum=sum+i;//add odd number

           }

       }

      System.out.print(sum);//use print method to print sum value

   }

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

   {

       Scanner ox=new Scanner(System.in);//creating Scanner object

       int n= ox.nextInt();//defining integer variable for input value

       System.out.print(odd_number_digits(n)+ "\n");//use print method to call method

       System.out.println("Sum of odd numbers: ");//print message

       sum_odd_digits(n);//calling method

   }

}

Output:

please find the attachment.

Explanation:

In the above code, two methods "odd_number_digits and sum_odd_digits" are defined in which the first method return type is boolean because it will true or false value, and the second method returns the sum of odd numbers.

In the "odd_number_digits" method,  an integer variable passes as an argument and inside the method, if block is used that check value is a positive and odd number then it will return a true value.

In the "sum_odd_digits" method, it accepts an integer parameter "n", and define integer variable "sum" inside the method, which uses the for loop, inside the loop if block is used that counts odd numbers and adds its in sum and print its value.
