What is the reason that friction is present in surface to surface contact?

The ability to present an effective message with useful content is obviously important to a good _____ presentation.

Zina [86]

A successful oral presentation depends on your ability to communicate your ideas clearly and with relevant content.

<h3>What is an oral expression? </h3>

Oral presentations, often known as public speaking or just presentations, involve one or more speakers discussing a particular topic with an audience.
This seeks to provide information, amuse, educate, and/or make a point.
When the author speaks in front of other students, coworkers, or other interested groups to convey the results of years of expertise and research while outlining essential elements to success, the book is referred to as an example of oral presentation.
An oral presentation is one of the best venues for fusing verbal prowess with powerful nonverbal indicators to extend your communication.
It enables people to speak in front of a live audience with assurance about their thoughts and opinions.

• Open your Netbeans IDE and answer the following question

VARVARA [1.3K]

Answer:

public static void main(String[] args)

{

int cdCount;

double cdCountAfterDiscount;

DecimalFormat df = new DecimalFormat("$##.##"); // Create a Decimal Formatter for price after discount

System.out.println("Enter the amount of CD's bought");

Scanner cdInput = new Scanner(System.in); // Create a Scanner object

cdCount = Integer.parseInt(cdInput.nextLine()); // Read user input

System.out.println("CD Count is: " + cdCount); // Output user input

if(cdCount <= 14 )

{

System.out.println("There is no discount");

System.out.println("The final price is " + cdCount*3.5);

}

if(cdCount >= 15 && cdCount<=50)

{

System.out.println("You have a 1% discount.");

cdCountAfterDiscount = (cdCount *3.5)-(3.5*.01);

System.out.println("The final price is " + df.format(cdCountAfterDiscount));

}

if(cdCount >= 51 && cdCount<120)

{

System.out.println("You have a 5% discount.");

cdCountAfterDiscount = (cdCount *3.5)-(3.5*.05);

System.out.println("The final price is " + df.format(cdCountAfterDiscount));

}

if(cdCount >= 120)

{

System.out.println("You have a 10% discount.");

cdCountAfterDiscount = (cdCount *3.5)-(3.5*.1);

System.out.println("The final price is " + df.format(cdCountAfterDiscount));

Write a program to calculate the great circle distance between two points on the surface of a sphere. If p1(x1, y1) and p2(x2,y2

Tamiku [17]

Answer:

import java.lang.*;

public class distance { public static double distance(double latitude1,

double latitude2, double longitude1,

double longitude2)

{

// Convert Latitude and Longitude to Radians

longitude1 = Math.toRadians(longitude1);

longitude2 = Math.toRadians(longitude2);

latitude1 = Math.toRadians(latitude1);

latitude2 = Math.toRadians(latitude2);

double d_longitude = longitude2 - longitude1;

double d_latitude = latitude2 - latitude1;

double a = Math.pow(Math.sin(d_latitude / 2), 2)

+ Math.cos(latitude1) * Math.cos(latitude2)

* Math.pow(Math.sin(d_longitude / 2),2);

double val = 2 * Math.asin(Math.sqrt(a));

// Radius of earth in kilometers is 6371

double earth_radius = 6371;

// Calculate and return the distance

return(val * earth_radius);

}

// Main Method

public static void main(String[] args)

{

double latitude1 = 67.32055555555556;

double latitude2 = 83.31861111111111;

double longitude1 = -1.7217899;

double longitude2 = -1.6567799;

System.out.println(distance(latitude1, latitude2,

longitude1, longitude2) + " K.M");

}

Explanation:

This program is implemented in Java programming language

The formula for the shortest distance between two points on the earth is:

Distance = 3963.0 * arccos[(sin(lat1) * sin(lat2)) + cos(lat1) * cos(lat2) * cos(long2 – long1)]

The latitude and longitude of the two points must be known

The latitude and longitude are converted into radians using built in methods in java.

Take value for the radius of the earth in Kilometers 6371;

Note that a seperate method has been created to calculate the distance

In the driver method (main), values for latitude and logitudes for both places have been hard-corded, then the method distance is called and passed those values

Note also that the distance has been calculated in Kilometers

What certification is provided by an APMG-International

White raven [17]

Answer:

The answer is "Agile".

Explanation:

Agile is a kind of cooperation among inter-functional, autonomous teams to recognize needs and solutions, that provides you development, economic growth, and delivery and facilitates a time-based, adaptive approach, that makes for a fast and efficient reaction to change.

APM Group also use for an International body specializing in human, corporate and electronic accreditation and evaluation and testing schemes.

It was founded in 1990 and works daily continuously through two decades, and because of some reason, this certification is also known as Agile.
