We use analog and digital signals in our everyday lives with the radio, the cell phone and with our own computers. our computers and our cell phones are all digital now but radio's are still considered analog. Radio telescopes explore space by using radio waves and signals to almost like scan space and collect data like a sonar in a submarine.

Radio telescopes are specialized “antenna” and a “radio receiver”. This is used to receive radio waves. It observes space by receiving radio signals.

Analog signal transmit data in the form of wave

Digital signal will be in the form of ones and zeros. High value represents 1 and low value represents 0. It is like on and off switch.

Eg.

Analog signal & Digital signal:

Aneriod barometer

digital signature

Digital photography

Digital Satellite system

Digital television

Cell phones

Analog computer

Answer:

words.hasNext()

Explanation:

Given the code snippet below:

  1.        while (inputFile.hasNextLine()) {
  2.            String word = "";
  3.            String line = inputFile.nextLine();
  4.            Scanner words = new Scanner(line);
  5.            while (words.hasNext()) {
  6.                word = words.next();
  7.            }
  8.            System.out.println(word); }
  9.    }

We have a inputFile Scanner object that can read data from a text file and we presume the inputFile has read several rows of data from the text file. So long as there is another line of input data available, the outer while loop will keep running. In each outer loop, one line of data will be read and assign to line variable (Line 3). Next, there is another Scanner object, words, which will take the current line of data as input. To get the last word of that line, we can use hasNext() method. This method will always return true if there is another tokens in its input. So the inner while loop will keep running so long as there is a token in current line of data and assign the current token to word variable. The word will hold the last token of current line of data upon exit from the inner loop. Then we can print the output (Line 8) which is the last word of the current line of data.

Why is it difficult to enforce laws against intellectual theft?
Mnenie [13.5K]

Answer:

The best answer is: all intellectual theft occurs online and through digital networks.

Explanation:

<em>Because the implementation is online and through the network, it is difficult to monitor and justify the safety of the victim and the theft. Internet is widely available to all individuals who has access to it. No matter what is the age, gender and nationality of the victim. It is difficult to maintain a law with its very wide scope and the audiences involved. </em>

Answer:

(a): power(2&-2)

The code is as follows:

<em>power = 2**-2</em>

<em>print(power)</em>

<em />

(b): Largest and smallest in a list

The code is as follows:

<em>num = [33,6,11,100,456,109,-4,366]</em>

<em>smallest= min(num)</em>

<em>largest= max(num)</em>

<em>print(smallest)</em>

<em>print(largest)</em>

<em />

(c): Loop in Python

(i) Loop are instructions that are repeated until a certain condition is met;

(ii) For loop, in python are used to iterate over a sequence or through a certain range;

The syntax is:

<em>for loop_element in range(iterating_range):</em>

The following is an illustration of for loop that iterates 5 times

<em>for i in range(5):</em>

Explanation:

(a): power(2&-2)

The ** is used to calculate power.

So, 2**-2 represents 2 raise to power -2

<em>power = 2**-2</em>

This prints the calculated power

<em>print(power)</em>

<em />

(b): Largest and smallest in a list

This initializes the list

<em>num = [33,6,11,100,456,109,-4,366]</em>

This calculates the smallest using min() function

<em>smallest= min(num)</em>

This calculates the largest using max() function

<em>largest= max(num)</em>

This prints the smallest and the largest

<em>print(smallest)</em>

<em>print(largest)</em>

<em />

(c): See answer section
