When the sun is overhead, light rays pass through less atmosphere, so less UV radiation is screened out. A solar cooker works like a one-way lobster trap. It lets UV light rays in and then converts them to longer infrared light rays that can't escape.

Answer:

A sort of solar thermal collector is a solar cooker. It "collects" and retains the thermal (heat) energy of the Sun. When high frequency light (visible and ultraviolet) is transformed into low frequency infrared radiation, heat is created.

import java.util.*;

//import package for taking input from user.

public class Main   //define class

{

public static void main (String ag[] )   //define main function

{

 int number;

 Scanner input = new Scanner(System.in);

 for (int i = 0; i < 5; i ++)                       //loo for input.

 {

  System.out.print ("Enter a number between 1 - 30:  ");

  number = input.nextInt();          //input number by the user.

 

 }

 asterisk();           //calling function.

 }

public static void asterisk()          //defination of function.

{

    //body of function.

    int n;                   //local variable.

 for (n= 0; n <= 30; n++)                  //using loop for print asterisk

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );                  //print value.

 }

 

  for (n= 0; n <= 30; n++)         //using loop for print asterisk

  {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );     //print value.

 }

 

  for (n= 0; n <= 30; n++)          //using loop for print asterisk

  {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );          //print value.

 }

  for (n= 0; n <= 30; n++)            //using loop for print asterisk

 

 {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );               //print value.

 }

 

  for (n= 0; n <= 30; n++)             //using loop for print asterisk

  {

 if (n !=0)

 //printf used for print value.

 System.out.printf("*", n );             //print value.

 }

}

}

Output:

Enter a number between 1 - 30: 2

Enter a number between 1 - 30: 2

Enter a number between 1 - 30: 1  

Enter a number between 1 - 30: 3

Enter a number between 1 - 30: 4

Write a function called PayLevel that returns a level given an Ssn as input. The level are: "Above Average" if the employee mak
kotykmax [81]

Answer:

Explanation:

Since no further information was provided I created the PayLevel function as requested. It takes the Ssn as input and checks it with a premade dictionary of Ssn numbers with their according salaries. Then it checks that salary against the average of all the salaries and prints out whether it is Above, Below, or Average. The output can be seen in the attached picture below.

employeeDict = {162564298: 40000, 131485785: 120000, 161524444: 65000, 333221845: 48000}

average = 68250

def PayLevel(Ssn):

   pay = employeeDict[Ssn]

   print("Employee " + str(Ssn) + " is:", end=" "),

   if pay > average:

       print("Above Average")

   elif pay < average:

       print("Below Average")

   else:

       print("Average")

PayLevel(161524444)

PayLevel(131485785)
