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

Which of the following statements best deceive the relationship between carrying capacity and population size

Andrej [43]

Hey lad, your questions options should be:

a. Carrying capacity increases population size.

b. Carrying capacity determines maximum populations size.

c. Population size is not affected by carrying capacity.

d. Population size increases the carrying capacity.

And B: Carrying capacity determines maximum populations size should be the right answer.

hope you get a victory royale with cheese on your assignment

Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicatin

lyudmila [28]

Answer:

Following is the program in C language :

#include <stdio.h> // header file

#define n 5 // macro

int main() main function

{

int a[n],k1; // variable and array declaration

printf("Enter the element:\n");

for(k1=0;k1<n;++k1) //iterating the loop

{

scanf("%d",&a[k1]);//Read the values by user

}

printf("Output in Reverse Order:\n");

for(k1=n-1;k1>=0;--k1)//iterating the loop

{

printf(" %d ",a[k1]); //Display the values

}

return 0;

}

Output:

Enter the element:

4

3

45

67

89

Output in Reverse Order: 89 67 45 3 4

Explanation:

Following is the description of the program

Define a macro "n" with value 5 after the header file.

Declared an array "a" and defined the size of that array by macro i.e "n".

Read the value by the user by using scanf statement in the array "a"

Finally In the last for loop display the values of array "a" by space.
