When traveling through a gas, the speed of sound depends primarily on the density of themedium. The less dense the medium, the faster the speed will be. The following tableshows the approximate speed of sound at 0 degree celsius, measured in meters per second,when traveling through carbon dioxide, air, helium, and hydrogen.MediumSpeed (meters per sec.)Carbon dioxide258.0Air331.5Helium972.0Hydrogen1270.0Write a program that displays a menu allowing the user to select one of these 4 gases. Aftera valid selection has been made, the program should ask the user to enter the number ofseconds (0 to 30) it took for the sound to travel in this medium from its source to thelocation at which it was detected. The program should then report how far away (inmeters) the source of the sound was from the detection location.

In the game Rock paper Scissors, two players simultaneously choose one of three options: rock, paper, or scissors. If both players choose the same option, then the result is a tie. However, if they choose differently, the winner is determined as follows: Rock beats scissors, because a rock can break a pair of scissors. Scissors beats paper, because scissors can cut paper. Paper beats rock, because a piece of paper can cover a rock. Create a game in which the computer randomly chooses rock, paper, or scissors. Let the user enter a character, r, p, or s, each representing one of the three choices. Then, determine the winner. Save the application as RockPaperScissors.cs.
Suppose you can buy chocolate bars from a vending machine for $1 each.Inside every chocolate bar is a coupon. You can redeem 7 coupons for 1chocolate bar from the machine.For example, if you have $20, you can initially buy 20 chocolate bars.This gives you 20 coupons. You can redeem 14 coupons for 2 additionalchocolate bars. These 2 chocolate bars have 2 more coupons, so you now have atotal of 8 coupons. This gives you enough to redeem for 1 final chocolate bar.Write a recursive function that would accept the amount of dollars andcoupons as its parameters and output the total number of chocolate bars thatcan be bought (including those redeemed via coupons).Write a test program in C++that would allow the user to enter amount of dollarsand then use the recursive function to compute the number of chocolate barsthe user can buy, and output the number to the screen.
Suppose you save $100 each month in a savings account with annual interest rate 3.75%. Thus, the monthly interest rate is 0.0375/12 = 0.003125. After the first month, the value in the account becomes 100 * (1 + 0.003125) = 100.3125, after the second month, the value in the account becomes (100 + 100.3125) * (1 + 0.003125) = 200.938, after the third month, the value in the account becomes (100 + 200.938) * (1 + 0.003125) = 301.878 and so on. Write a Java program that prompts the user to enter a monthly saving amount and displays the account value after the sixth month. (You will use a loop to simplify the code and display the account value for any month.) Sample Output:Enter the monthly saving amount: 100After the first month, the account value is 100.3125After the second month, the account value is 200.9384765625After the third month, the account value is 301.8789093017578Note: The computation should be until 12 months.

Find the Other Two Side Lengths in Java Given the shortest side of a 30° by 60° by 90° triangle, find out the other two sides. Return the longest side and medium-length side in that order. Examples otherSides(1) ➞ [2.0, 1.73] otherSides(12) ➞ [24.0, 20.0] otherSides(2) ➞ [4.0, 3.46] otherSides(3) ➞ [6.0, 5.2] Notes 30° by 60° by 90° triangles always follow this rule: let's say the shortest side length is x units, the hypotenuse would be 2x units and the other side would be x * square root of 3. The results in the Tests are rounded up to 2 decimal places. Return the result as an array.

You have a group of friends coming to visit for your high school reunion, and you want to take them out to eat at a local restaurant. You are not sure if any of them have dietary restrictions, but your restaurant choices are as follows: Joe’s Gourmet Burgers—Vegetarian: No, Vegan: No, Gluten-Free: No Main Street Pizza Company—Vegetarian: Yes, Vegan: No, Gluten-Free: Yes Corner Café—Vegetarian: Yes, Vegan: Yes, Gluten-Free: Yes Write a program that asks whether any members of your party are vegetarian, vegan, or gluten-free, to which then displays only the restaurants to which you may take the group.
A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consume in a day. Then, she calculates the number of calories that result from the fat using the following formula: Calories from fat = Fat grams × 9Next, she calculates the number of calories that result from the carbohydrates using the following formula: Calories from carbs = Carbs grams × 4Create an application that will make these calculations. In the application, you should have the following methods:• FatCalories–This method should accept a number of fat grams as an argument and return the number of calories from that amount of fat.• CarbCalories–This method should accept a number of carbohydrate grams as an argument and return the number of calories from that amount of carbohydrates.
