differentiate between refraction of light and reflection of light

Answers

Answer 1

Refraction represents a change in the direction of propagation when beams of light encounter a medium with a different density.

Reflection is the return of light to the medium it came from when it encounters a mirror.

Using the Caesar cipher, "HELLO" is encrypted to "OLSSV" by applying a shift of 7. The number 7 is considered the __________

Answers

Answer:

The offset

Explanation:

In the question, we understand that the original text is HELLO and the encrypted text is OLSSV.

It should be noted that O replaced H, L replaced E, S replaced L and V replacement O.

This is made possible by a term refered to as offset.

The offset is used to determine the character that will replace another when it is encrypted.

7 characters after H is O; this is same for every other characters in the text.

The example given represents a simple shift cipher encryption with each letter in the original text shifted by a fixed value. Hence, the shift value of 7 used in the cipher given is called the key.

Each alphabet on the original text, HELLO is shifted by the key 7 to produce :

H + 7 alphabets gives OE + 7 alphabets gives LL + 7 alphabets gives SL + 7 alphabets gives SO + 7 alphabets gives V

This produces the encryption OLSSV, hence, with the shift of 7 known the encryption letters are each reversed by 7 to obtain the actual phrase 'HELLO'.

Write a method called removeHighPrice that will go through a provided ArrayList called prices and removes the first price that is more than $5.00 and return the new ArrayList. If a price over $5 is not found, it returns the original ArrayList.

Answers

Answer:

The method written in Java is as follows:

public static ArrayList<Double> removeHighPrice (ArrayList<Double> prices){

       for(int i =0;i<prices.size();i++){

     if(prices.get(i) > 5.00){

         prices.remove(i);  

         break;

     }

 }

 return(prices);  

 }

Explanation:

This line declares the method

public static ArrayList<Double> removeHighPrice (ArrayList<Double> prices){

This line iterates through the ArrayList named prices

       for(int i =0;i<prices.size();i++){

This checks if current price is greater than 5

     if(prices.get(i) > 5.00){

If yes, the price is removed

         prices.remove(i);  

And the loop is terminated

         break;

     }

 }

This returns the ArrayList

 return(prices);  

 }

Does magnetic tape require a laser to read data?

The data in magnetic tape consists of information that has been digitized into discrete numbers by means of of a recording device which can also be able to read the recorded data on the tapes

As the magnetized tape passes under a current carrying conductor, the data on the magnetized surface can be sensed

Due to the arrangement of the magnetic tapes in their stored format, the process of retrieving information makes use of serial access such that information retrieval is slow.

What is the use of consonant in QBASIC ? Answer me in short and easy answer.​

Answers

Answer:

See Explanation

Explanation:

I'll assume the question is about the use of constants in QBasic because consonants do not have any special function or usage in QBasic.

In simple terms: In QBasic, constants are used to represent elements that do not change in value during program execution.

Take for instance, you intend to use [tex]\pi[/tex] in your program.

Its value is [tex]\pi = 3.142[/tex]

So, 3.142 will always be a constant in your program. One of the ways it can be used in a program is:

10 LET PI = 3.142

The above represents a numeric constant. QBasic also have string constants.
