The answer is a Scanning Electron Microscope

It is important to obtain and prepare proper samples when using SEM. The sample’s size, state, and shape are things that should be considered before the sample preparation. Some samples need to be coated. Most metals require no preparation since they can easily conduct electricity. Non-metals, however, needs to be coated with a thin layer of gold. Gold is the ideal non-metal and works most of the times.

What is the output?
olga55 [171]

Answer:

The output is 28

Explanation:

Required

Determine the output of the code segment

The first line initializes "answer" to 0

The next two lines iterate through lists [2,4] and [3,5

Each of these lists have two elements; So, the number of iterations is 2 * 2 i.e. 4.

In the first iteration

numA = 2, numB = 3, answer = 0

So:

answer = answer + numA + numB= 0 + 2 + 3 = 5

In the second iteration

numA = 2, numB = 5, answer = 5

So:

answer = answer + numA + numB= 5 + 2 + 5 = 12

In the third iteration

numA = 4, numB = 3, answer = 12

So:

answer = answer + numA + numB= 12 + 4 + 3 = 19

In the fourth iteration

numA = 4, numB = 5, answer = 19

So:

answer = answer + numA + numB= 19 + 4 + 5 = 28

Lastly, the value of "answer" is printed

<em>Hence, the output is 28</em>

List three types of cardinalities for relationships within a relational database.
Afina-wow [57]
This is about identifiers in a record referring to other records.
You can have many to one, one to one, many to many.

E.g., if you have two tables, Authors and Books, then a book record could have a reference to an author record. Since an author can write many books, this would be a many-to-one relationship.
