<u>2 logs is </u>the virus removal credit awarded to a properly operated conventional treatment plant.

<h3>What is the log removal for viruses?</h3>

A log removal value (LRV) is a measurement of the ability of treatment processes to remove pathogenic microorganisms. LRVs are specified by taking the logarithm of the ratio of pathogen concentration in the influent and effluent water of a restorative process (shown in Equation 1).

<h3>What is log inactivation?</h3>

“Log inactivation” is a suitable way to express the number or percent of microorganisms inactivated (killed or unable to replicate) through the disinfection process. For example, a 3 log inactivation value means that 99.9% of microorganisms of claim have been inactivated.

Coding is a skill where you take instructions (the steps in a task) and translate it into a language the computer understands since computers do not language.

Explanation:

Coding is a skill where you take instructions (the steps in a task) and translate it into a language the computer understands since computers do not communicate like humans. They communicate in a language called BINARY and it is uses 0's and 1's. Coders write the instructions using a programming language.

erastovalidia [21]

Answer:

D. fossil record

Explanation:

When animals and plants died in historical times , in some cases their remains were preserved as imprints on rocks. These constitute fossil records and provide lot of information about evolution of life. These fossil records when arranged chronologically in order of time, constitute a fossil record. Fossil Record provides a very valuable indirect insight about historical times to archaeologists.

Write a program that prompts the user to enter the month and year and displays the number of days in the month. For example, if

valentinak56 [21]

Answer:

Following are the program in JAVA language

import java.util.Scanner; // import package

import java.util.Calendar; // import package

public class Main // class main

{

public static void main(String[] args) // main function

{

Scanner input = new Scanner(System.in); // for user input

Calendar calendar = Calendar.getInstance(); //get calendar instance for methods

int nYear , nMonth , date =1 , nDays;

String MonthOfName = "";

System.out.print(" Enter a month in the year :");

nMonth = input.nextInt(); //input Month

System.out.print("Enter a year :");

nYear = input.nextInt(); //Input Year

switch (nMonth) //Find month name via 1-12

{

case 1:

MonthOfName = "January";

nMonth = Calendar.JANUARY;

break;

case 2:

MonthOfName = "February";

nMonth = Calendar.FEBRUARY;

break;

case 3:

MonthOfName = "March";

nMonth = Calendar.MARCH;

break;

case 4:

MonthOfName = "April";

nMonth = Calendar.APRIL;

break;

case 5:

MonthOfName = "May";

nMonth = Calendar.MAY;

break;

case 6:

MonthOfName = "June";

nMonth = Calendar.JUNE;

break;

case 7:

MonthOfName = "July";

nMonth = Calendar.JULY;

break;

case 8:

MonthOfName = "August";

nMonth = Calendar.AUGUST;

break;

case 9:

MonthOfName = "September";

nMonth = Calendar.SEPTEMBER;

break;

case 10:

MonthOfName = "October";

nMonth = Calendar.OCTOBER;

break;

case 11:

MonthOfName = "November";

nMonth = Calendar.NOVEMBER;

break;

case 12:

MonthOfName = "December";

nMonth =Calendar. DECEMBER;

}

calendar.set(nYear, nMonth, date); // set date to calender to get days in month

nDays=calendar.getActualMaximum(Calendar.DAY_OF_MONTH); // get no of days in month

System.out.println(MonthOfName + " " + nYear + " has " + nDays + " days."); //print output

}

Output:

Enter a month in the year : : 09

Enter a year : 2019

September 2019 has 30 days.

Explanation:

In this program we have take two user input one for the month and other for the year Also take two variables which are used for storing the month name and no of days in a month. with the help of switch we match the cases and store the month value .After that set the date to calender with help of calendar.set(nYear, nMonth, date) method and To get the number of days from a month we use calendar.getActualMaximum(Calendar.DAY_OF_MONTH); method and finally print year and days.

1. Explain the distinction between interpretation and compilation. What are the comparative advantages and disadvantages of the

serious [3.7K]

Answer:

11: Compiler translates a high level source program into a target equivalent (machine language).

An interpreter implements a virtual machine, the high-level programming language of which is the "machine language." The interpreter reads statements more or less one at a time in that language, and executes them as they go along.

12: One could also consider Java either. A compiler (complicated translator) can create code, which is then executed by a complicated virtual machine (interpreter)

13: A preprocessor is an initial translator which removes comments and white space, and group characters together into tokens such as keywords, identifiers, numbers, and symbols, as well as simple syntactic structure analyses. A compiler uses in-depth analysis and nontrivial transformation.

14: C++ implementations based on the early AT&T compiler created an intermediate program in C rather than assembly language

15: Stack-based language, similar to modern Java compiler byte code

16: A method in which a simple interpreter implementation evolves into building more complex versions until the compiler is built.

17: A compiler which translates byte code into machine language immediately prior to each program execution.

18: Lisp and Prolog

19: TEX and TROFF are one of such compilers that translate high-level document descriptions into laser printer or phototypesetter commands. Query language processors for database systems are also compilers that translate languages such as SQL into primitive file operations.

21: without havin to call multiple tools with command-line tools, You can write an entire program in an IDE.
