This question is related to the emission of electrons when light shines on an metal. (Photoelectric effect)

With the classical theory, it was thought that increasing or decreasing the intensity of light would increase or decrease the kinetic energy of the electron.,

Another expected result was that time gap between when light strikes the metal and when electrons are ejected, would depend on the intensity of such light.

However, the experimental results were not consistent with the particle theory of light. So your answer is A.

Later on this effect was correctly explained by Einstein based on Planck's findings.

If you aren’t familiar with the idea of a leap year, read “Why Is There a Leap Day?” before continuing with the lab.

The correct debugged code is attached below

A leap year is a year with 366 days and this year occurs once every 4 years. The debugged code line of code of the program written, is as attached below. because the line of code in the question lacks some functions and symbols

Hence we can conclude that the correct debugged code is attached below.

Create a program that calculates three options for an appropriate tip to leave after a meal at a restaurant.

max2010maxim [7]

Complete Question:

Python Programming: Create a program that calculates three options for an appropriate tip to leave after a meal at a restaurant and repeats if the user enters "y" or "Y" to continue.

Print the name of the application "Tip Calculator"

- Get input from the user for "Cost of meal: "

- Calculate and display the "Tip Amount" and "Total Amount" at a tip_percent of 15%, 20%, and 25%.

- Use a FOR loop to iterate through the tip_percent

- The formula for calculating the tip amount is: tip = cost of meal * (tip percent / 100)

- The program should accept decimal entries like 52.31. Assume the user will enter valid data.

- The program should round the results to a maximum of two decimal places . At the "Continue? (y/n)" prompt, the program should continue only if the user enters “y” or “Y” to continue.

- Print "Bye!" or a salutation at the end of the program

Answer:

Answered in Python

print("Tip Calculator")

tryagain = "y"

while tryagain == "y" or tryagain == "Y":

amount = float(input("Cost of Meal: "))

for tip_percent in range(15,26,5):

print(str(tip_percent)+"%")

print("Tip Amount: "+str(round(tip_percent * amount/100,2)))

print("Total Amount: "+str(round(amount + (tip_percent * amount/100),2)))

tryagain = input("Continue?y/n: ")

print("Bye!")

Explanation:

This prints the name of the calculator

print("Tip Calculator")

This initializes tryagain to yes

tryagain = "y"

While tryagain is yes, the following loop is repeated

while tryagain == "y" or tryagain == "Y":

This prompts user for amount of meal

amount = float(input("Cost of Meal: "))

This gets the tip_percent which is 15%, 20% and 25% respectively

for tip_percent in range(15,26,5):

This prints the tip_percent

print(str(tip_percent)+"%")

This calculates and prints the tip amount rounded to 2 decimal places

print("Tip Amount: "+str(round(tip_percent * amount/100,2)))

This calculates and prints the total amount rounded to 2 decimal places

print("Total Amount: "+str(round(amount + (tip_percent * amount/100),2)))

This prompts user to continue or not

tryagain = input("Continue?y/n: ")

The program ends here

print("Bye!")

Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the n

mote1985 [20]

Answer:

import java.util.Scanner;

public class VowelsAndConsonantsDemo {

/**

The printMenu methods displays a menu to the user

public static void printMenu() {

System.out.println("Please select an option: ");

System.out.println();

System.out.print("a. Count the number of vowels in the string.\n"

+ "b. Count the number of consonants in the string.\n"

+ "c. Count both the vowels and consonants in the string.\n"

+ "d. Enter another string.\n"

+ "e. Exit the program\n");

}

public static void main(String[] args) {

String input; // to hold the user's input

String option; // to hold the user's input

char choice; // to hold a single character

char exit; // user chooses 'e' to exit the program

char letter; //the Y or N from the user's decision to exit

// create a Scanner object to read keyboard input.

// Scanner keyboard = new Scanner(System.in);

Scanner keyboard;

do {

keyboard = new Scanner(System.in);

// ask user to enter string

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

input = keyboard.nextLine();

input = input.toLowerCase();

System.out.println();

printMenu();

option = keyboard.nextLine();

choice = option.charAt(0);

VowelsAndConsonants words = new VowelsAndConsonants(input);

switch (choice) {

case 'a':

case 'A':

System.out.println("Number of Vowels: " + words.getVowels());

break;

case 'b':

case 'B':

System.out.println("Number of Consonants: " + words.getConsonants());

break;

case 'c':

case 'C':

System.out.println("Number of Vowels & Consonants: " + words.getConsonants()

+ words.getVowels());

break;

case 'd':

case 'D':

System.out.println("Enter a string: ");

break;

case 'e':

case 'E':

System.exit(0);

break;

default:

System.out.println("You did not enter a valid choice.");

}

// keyboard.nextLine(); //consumes the new line character after the choice

// String answer = keyboard.nextLine();

// letter = answer.charAt(0);

} while (true);

}
