Answer:

They record a person's surroundings.

Explanation:

Motion sensors like the passive infrared (PIR) work by detecting changes in the infrared radiation given off by objects in their surroundings. Normally most objects give off a small amount of infrared radiation. Human bodies, however, give off a large amount of infrared radiation.

So when motion sensors detect the presence of a person in a surrounding, they give off an alarm to indicate the presence of an intruder.

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

With cybersecurity theory, security standards, frameworks and best practices we can guard against cyber attacks and easy-to-guess passwords such as using alphanumeric password with certain composition and strength.

Some examples of the Internet sources that hackers use to gather information about a company's employees includes;

I. Blogs.

II. Company website.

III. Social networking sites.

However, Regional Internet registries cannot be used by hackers to gather information about a company's employees because it is an internet protocol resource organization saddled with the responsibility of allocating and registering internet protocol (IP) addresses.

Explanation:

In Computer science, an algorithm can be defined as a standard formula or procedure which comprises of set of finite steps or instructions for solving a problem on a computer.

Basically, the time complexity of an algorithm is defined by f(n) if; for all "n" and all inputs with length "n" the execution of the algorithm takes a maximum of f(n) steps. Therefore, this is a measure of the efficiency of an algorithm.

Hence, the time complexity is a measure of the amount of time required by an algorithm to run till its completion of the task with respect to the length of the inpu

Computational complexity can be defined as a measure of software complexity that measure how complex a software is in machine's viewpoint in terms of how the size of the input data affects an algorithm's usage of computational resources such as memory or running time.

Explanation:

A computer might be described with deceptive simplicity as “an apparatus that performs routine calculations automatically.” Such a definition would owe its deceptiveness to a naive and narrow view of calculation as a strictly mathematical process. In fact, calculation underlies many activities that are not normally thought of as mathematical. Walking across a room, for instance, requires many complex, albeit subconscious, calculations. Computers, too, have proved capable of solving a vast array of problems, from balancing a checkbook to even—in the form of guidance systems for robots—walking across a room.

Before the true power of computing could be realized, therefore, the naive view of calculation had to be overcome. The inventors who laboured to bring the computer into the world had to learn that the thing they were inventing was not just a number cruncher, not merely a calculator. For example, they had to learn that it was not necessary to invent a new computer for every new calculation and that a computer could be designed to solve numerous problems, even problems not yet imagined when the computer was built. They also had to learn how to tell such a general problem-solving computer what problem to solve. In other words, they had to invent programming.

They had to solve all the heady problems of developing such a device, of implementing the design, of actually building the thing. The history of the solving of these problems is the history of the computer. That history is covered in this section, and links are provided to entries on many of the individuals and companies mentioned. In addition, see the articles computer science and supercomputer.

Early history

Computer precursors

The abacus

The earliest known calculating device is probably the abacus. It dates back at least to 1100 BCE and is still in use today, particularly in Asia. Now, as then, it typically consists of a rectangular frame with thin parallel rods strung with beads. Long before any systematic positional notation was adopted for the writing of numbers, the abacus assigned different units, or weights, to each rod. This scheme allowed a wide range of numbers to be represented by just a few beads and, together with the invention of zero in India, may have inspired the invention of the Hindu-Arabic number system. In any case, abacus beads can be readily manipulated to perform the common arithmetical operations—addition, subtraction, multiplication, and division—that are useful for commercial transactions and in bookkeeping.

The abacus is a digital device; that is, it represents values discretely. A bead is either in one predefined position or another, representing unambiguously, say, one or zero.

Analog calculators: from Napier’s logarithms to the slide rule

Calculating devices took a different turn when John Napier, a Scottish mathematician, published his discovery of logarithms in 1614. As any person can attest, adding two 10-digit numbers is much simpler than multiplying them together, and the transformation of a multiplication problem into an addition problem is exactly what logarithms enable. This simplification is possible because of the following logarithmic property: the logarithm of the product of two numbers is equal to the sum of the logarithms of the numbers. By 1624, tables with 14 significant digits were available for the logarithms of numbers from 1 to 20,000, and scientists quickly adopted the new labour-saving tool for tedious astronomical calculations.

Most significant for the development of computing, the transformation of multiplication into addition greatly simplified the possibility of mechanization. Analog calculating devices based on Napier’s logarithms—representing digital values with analogous physical lengths—soon appeared. In 1620 Edmund Gunter, the English mathematician who coined the terms cosine and cotangent, built a device for performing navigational calculations: the Gunter scale, or, as navigators simply called it, the gunter. About 1632 an English clergyman and mathematician named William Oughtred built the first slide rule, drawing on Napier’s ideas. That first slide rule was circular, but Oughtred also built the first rectangular one in 1633. The analog devices of Gunter and Oughtred had various advantages and disadvantages compared with digital devices such as the abacus. What is important is that the consequences of these design decisions were being tested in the real world.

Digital calculators: from the Calculating Clock to the Arithmometer

In 1623 the German astronomer and mathematician Wilhelm Schickard built the first calculator. He described it in a letter to his friend the astronomer Johannes Kepler, and in 1624 . .

Answer:

number = int(input("Enter number: "))

if (number % 4):

 print("{} is not divisible by 4".format(number))

else:

 print("{} is divisible by 4".format(number))

Explanation:

If the %4 operation returns a non-zero number, there is a remainder and thus the number is not divisable by 4.

Answer:

the CG would move toward the rear.

Explanation:

Adding a paper clip to the vertical stabilizer of your glider will, the CG would move toward the rear. The correct option is A.

The place on an item where the force of gravity is thought to act is known as the center of gravity (CG).

The gravitational pull is thought to be focused at the point where an object weighs on average. Depending on the object's size, shape, and mass distribution, the center of gravity will be in one place or another.

The impact of adding a paper clip to your glider's vertical stabilizer is to shift the center of gravity (CG) to the back of the glider.

This is due to the fact that the paper clip adds weight to the glider's rear, moving the center of mass there and, as a result, the center of gravity.

Thus, the correct option is A.

Answer:

CIRCLE.JAVA

public class Circle {

  private double radius;

  public Circle(double myRadius) {

    radius = myRadius;

    private void setRadius(int myRadius){

    radius = myRadius;

 }

 public double getDiameter() {

    return radius*2;

 }

 public double getRadius() {

   return radius;

 }

 public double getPerimeter() {

   return Math.PI*getDiameter();

 }

    System.out.println(circ);

    System.out.println("The diameter is " + circ.getDiameter());

    System.out.println("The perimeter is " + circ.getPerimeter())

 }

}

Explanation:

public class Circle {

  //This could be made private or public.

  //Making it private is better

  private double radius;

  //This is a constructor. It should be made public

  //since it would most likely be used in another class

  //to create an object of this class.

  //Making it private means no other external class can create

  //an object of this class.

  //Since the tester class (CIRCLETESTER.java), as shown on line 3,

  // needs to create

  //an object of this class, this should be made public

  public Circle(double myRadius) {

    radius = myRadius;

    private void setRadius(int myRadius){

    radius = myRadius;

 }

 //This should be made public since it will be

// used in another class (CIRCLETESTER.java in this case)

 public double getDiameter() {

    return radius*2;

 }

 public double getRadius() {

   return radius;

 }

 //This should be made public since it will be

 //used in another class (CIRCLETESTER.java)

 public double getPerimeter() {

   return Math.PI*getDiameter();

 }

 //The toString() method is the string representation

 //of an object and is called when there is an attempt to

 //print the object. It should be made public since it will

 //be used in another class (CIRCLETESTER.java)

 public String toString() {

    return "Circle with a radius of " + radius;

 }

}

{

  public static ArrayList<Integer> getOdds(ArrayList<Integer> val)//defining a static method getOdds as an ArrayList

  {

      ArrayList<Integer> odd = new ArrayList<Integer>();//creating ArrayList Object  

      int i; //defining integer variable  

      for(i=0;i<val.size();i++)//defining for loop for calculating odd values

      {

          if(val.get(i)%2!=0)//defining if block to check odd numbers

          {

              odd.add(vals.get(i));//add values in odd ArrayList  

          }

      }

      return odd;//return ArrayList odd

  }

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

  {

      int l,i;//defining integer variable

      Scanner sob = new Scanner(System.in);//creating Scanner calss Object

      ArrayList<Integer> num = new ArrayList<Integer>();//creating ArrayList object  

      System.out.println("Enter length of the ArrayList: ");//print message

       l = scan.nextInt();//input length value

      System.out.println("Enter ArrayList values: "); //print message  

      for(i = 0; i < l; i++)//use for to input value  

      {

          num.add(sob.nextInt());//input value

      }

      System.out.println("Odds list: " + getOdds(num));//calling method getOdds

}

Output:

Enter ArrayList length:

Enter values:

8

6

7

3

12

Odds list: [5, 7, 3]

Original list: [2, 5, 8, 6, 7, 3, 12]

Explanation:

In the above-program inside the class, a static method "getOdds "is declared, that accepts an array list in its parameters, and defined an array list "odd", in this a for loop is defined, that check the odd numbers in the array and add the value in the odd Arraylist, and returns its values.

Inside the main method is defined that creates scanner class object for input array value and pass the value into the method "getodds" and print its return values.

Answer:

The answer is "variables".

Explanation:

It is necessary to declare a variable privately when declaring a class because the private variable 'protects' the code while it is in operation. It may not aim to protect it at this stage from changing the codes themselves for other developers. Its purpose of the so-called "data hiding" is to hold the internal data from many other classes using the class protected.
