Answer:

It can identify the sources of polluted water.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

A scientific method can be defined as a research method that typically involves the use of experimental and mathematical techniques which comprises of a series of steps such as systematic observation, measurement, and analysis to formulate, test and modify a hypothesis.

An example of how science can solve social problems is that it can identify the sources of polluted water through research, conducting an experiment or simulation of the pollution by using a computer software application.

In conclusion, science is a field of knowledge that typically involves the process of applying, creating and managing practical or scientific knowledge to solve problems and improve human life.

Explanation:

The code segment is not properly formatted; However, I will give a general explanation and a worked example.

In c++, setprecision are used to control the number of digits that appears after the decimal points of floating point values.

setprecision(0) means; no decimal point at all while setprecision(1) means 1 digit after the decimal point

While fixed is used to print floating point number in fixed notation.

Having said that:

Assume the code segment is as follows:

number = 12.345;

cout<<fixed;

cout<<setprecision(0);

cout<<number <<endl;

The output will be 12 because setprecision(0) implies no decimal at all; So the number will be rounded up immediately after the decimal point

Answer:

The method is as follows:

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

    double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

    if(d == r1 + r2){

        System.out.print("The circles touch each other");     }

    else if(d > r1 + r2){

        System.out.print("The circles do not touch each other");     }

    else{

        System.out.print("The circles intersect");     }

}

Explanation:

This defines the method

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

This calculate the distance

    double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

If the distance equals the sum of both radii, then the circles touch one another

    if(d == r1 + r2){

        System.out.print("The circles touch each other");     }

If the distance is greater than the sum of both radii, then the circles do not touch one another

   else if(d > r1 + r2){

        System.out.print("The circles do not touch each other");     }

If the distance is less than the sum of both radii, then the circles intersect

   else{

        System.out.print("The circles intersect");     }

}

Explanation:

This is a solution in javascript leveraging several powerful constructs in that language, such as the spread operator.

Answer:

The function is as follows:

def addingAllTheWeirdStuff(array1,array2):

   sumOdd = 0

   for i in array2:

       if i % 2 == 1:

           sumOdd+=i

   for i in array1:

       if i < 10:

           sumOdd+=i

   print("Sum:",sumOdd)

   sumEven = 0

   for i in array1:

       if i % 2 == 0:

           sumEven+=i

   for i in array2:

       if i > 10:

           sumEven+=i

   print("Sum:",sumEven)

Explanation:

This declares the function

def addingAllTheWeirdStuff(array1,array2):

This initializes the sum of odd numbers in array 2 to 0

   sumOdd = 0

This iterates through array 2

   for i in array2:

This adds up all odd numbers in it

       if i % 2 == 1:

           sumOdd+=i

This iterates through array 1

   for i in array1:

This adds up all elements less than 10 to sumOdd

       if i < 10:

           sumOdd+=i

This prints the calculated sum

   print("Sum:",sumOdd)

This initializes the sum of even numbers in array 1 to 0

   sumEven = 0

This iterates through array 1

   for i in array1:

This adds up all even numbers in it

       if i % 2 == 0:

           sumEven+=i

This iterates through array 2

   for i in array2:

This adds up all elements greater than 10 to sumEven

       if i > 10:

           sumEven+=i

This prints the calculated sum

   print("Sum:",sumEven)

Answer:

SELECT TripName

FROM AllTrips

WHERE Trip NOT LIKE ‘NH%'

Explanation:

Required

Fill in the blanks

The table name is not stated; so, I assumed the table name to be AllTrips.

The explanation is as follows:

This select the records in the TripName column

SELECT TripName

This specifies the table where the record is being selected

FROM AllTrips

This states the fetch condition

WHERE Trip NOT LIKE ‘NH%'

Note that:

So, the clause NOT LIKE 'NH%' will return records that do not begin with NH

Answer:

The illustration in Java is as follows:

import java.util.*;

import java.lang.Math.*;

class Main{

public static void main (String[] args){

 Scanner input = new Scanner(System.in);

 double num, root, temp;

 num = input.nextDouble();

 temp = num;

 while (true){

  root = 0.5 * ( (num / temp)+temp);

  if (Math.abs(root - temp) < 0.00001){

   break;   }

  temp = root;  }

 System.out.println("Root: "+root);

}}

Explanation:

This declares all necessary variables

 double num, root, temp;

This gets input for num (i.e the number whose square root is to be calculated)

 num = input.nextDouble();

This saves the input number to temp

 temp = num;

This loop is repeated until it is exited from within the loop

 while (true){

Calculate temporary square root

  root = 0.5 * ( (num / temp)+temp);

The loop is exited, if the absolute difference between the root and temp is less than 0.00001

  if (Math.abs(root - temp) < 0.00001){

   break;   }

Save the calculated root to temp

  temp = root;  }

This prints the calculated root

 System.out.println("Root: "+root);

Answer:

C15H24O

Explanation:

n(C) = 4.497 g/44g/mol = 0.1022

Mass of C = 0.1022 × 12 = 1.226 g

n(H) = 1.473g/18 g/mol = 0.0823 ×2 moles = 0.165 moles

Mass of H = 0.0823 × 2 ×1 = 0.165g

Mass of O= 1.501 -(1.226 + 0.165)

Mass of O= 0.11 g

Number of moles of O = 0.11g/16g/mol = 0.0069 moles

Dividing through by the lowest ratio;

0.1022/0.0069, 0.165/0.0069, 0.0069/0.0069

15, 24, 1

Hence the formula is;

Answer:

chosen ciphertext

Explanation:

Chosen ciphertext attack is a scenario in which the attacker has the ability to choose ciphertexts C i and to view their corresponding decryptions – plaintexts P i . It is essentially the same scenario as a chosen plaintext attack but applied to a decryption function, instead of the encryption function.

Cyber attack usually associated with obtaining decryption keys that do not run in fixed time is called the chosen ciphertext attack.

Hence, chosen ciphertext attempts the use of modular exponentiation.

Dear students,

The purpose of this memorandum is to let you all know the requirements of an ideal computer room.

1.- The compute room should be a decent, large, space, ready to accommodate the number of students that are going to participate in class.

2.- The proper temperature levels. All the hardware can't stand too much heat. We need ventilators and the right temperature for safety purposes.

3.- The organization of the PCs on every desk must be precise in order to have enough room for everybody's participation and interaction.

4.- Have a proper fire suppression system in place. The risk of fire when working with electronics is considerable.

5.- Access control. The equipment is expensive and must be just for qualified students. Have the proper control-access system to keep the place safe.

Thank you for your attention.

Answer:

Here the answer is given as follows,

Explanation:  

The real-life situation of a deadlock resolution where a role is played by the victim is given as follows:  

Example: An example of such a situation are often a one-way lane where the flow of traffic is merely in a method. Thus, on just one occasion, the flow of traffic can enter one direction only. Each entrance/exit gate is often considered a resource. during this case, if two cars are coming from both the entrances and that they are often considered as two tasks, then one among the cars must copy or we will say hand over its resource in order that the opposite car gets the prospect to first cross the lane or we will say the opposite task gets executed.  

 a)  Victim: The steps which describe how a victim is chosen are given as follows :  

   The task which is terminated so as to interrupt things of deadlock is taken into account because of the victim.

There are often a variety of job pools that will be under a deadlock situation and therefore the victim is usually a low-priority task in order that the performance isn't affected that much and termination of this task doesn't cause any effect on the opposite jobs.

the main positive effect of selecting and terminating a victim is that things of deadlock are resolved and every one of the tasks can execute now.

The negative effect is that the task that's chosen because the victim is terminated and is executed at the previous. This whole process for choosing a victim then terminating it then restarting it again may consume some longer also.

b)  An easy deadlock priority is often set. this suggests that the victim’s task or the task is often terminated so as to interrupt the deadlock and other jobs can finish executing. After this, the task which is terminated are often later restarted and every one of the tasks can then execute without a deadlock.

 c) When employment gets terminated, the knowledge associated with it's stored. Are often This is often done in order that the work can be restarted again and therefore the information in it's not lost. Since the progress of the victim is stopped. Thus, the sole thanks to complete the victim’s task would be to start out it again. But before restarting the task, this must be considered that the victim’s task doesn't cause any deadlock within the system.
