Speed of Sound
The following table shows the approximate speed of sound in air, water, and steel.
Create an application that displays a set of radio buttons allowing the user to select air, water, or steel. Provide a text box to let the user enter the distance a sound wave will travel in the selected medium. Then, when the user clicks a button, the
Format the output to two decimal places.
Input validation: Do not accept distances less than 0. Always check for nonnumeric data.
Use the following test data to determine if the application is calculating properly:

- GPA Calculator Students are concerned about their GPA. They need to calculate it accurately every semester to monitor their progress. Develop a GPA calculator that follows the AOU regulations (AOU-OU Grade Scale) using C# programming language. The application asks the student to enter his numeric grade of each course and the course's credit hours. Accordingly, the application calculates the student's GPA after converting the numeric grade to letter grade. The GPA calculation should produce floating-point results. Display the results rounded to the nearest hundredth. You should store the letter grades of all student's courses in an array. The final grade of the student should be also calculated. Sample I/O Enter the course grade (-1 to end): 93 Enter the course credit hours: 3 Enter the course grade (-1 to end): 74 Enter the course credit hours: 2 Enter the course grade (-1 to end): 60 Enter the course credit hours: 3 Enter the course grade (-1 to end): -1 The grades of your courses…arrow_forwardنقطة واحدة Keywords in Visual Basic are * words that are used as prefixes for control names (such as text, btn, LBL, and Ist). is used to name controls, such as TextBox1, Command2, etc. should be used Find when naming variables. have special meaning and should not be used Find when naming variables. هذا السؤال مطلوب نقطة واحدة The default property for a text box control is Enable O Text Multiline Password char Oarrow_forwardPercentage of vehicles: Write an interactive program that asks the users to input the number of cars, trucks and suv that entered a parking lot.

- Falling Distance When an object is falling because of gravity, the following formula can be used to determine the distance the object falls in a specific time period: d =1/2gt2 The variables in the formula are as follows: d is the distance in meters, g is 9.8, and t is the amount of time in seconds that the object has been falling. Create an application that allows the user to enter the amount of time that an object has fallen and then displays the distance that the object fell. The application should have a method named FallingDistance. The FallingDistance method should accept an object’s falling time (in seconds) as an argument. The method should return the distance in meters that the object has fallen during that time interval.arrow_forwardYou’ll create both pseudocode and a flowchart to design an application that displays the following menu: Select a Planet 1. Mercury2. Venus3. Earth4. Mars5. Exit the programEnter your selection. When the user selects a planet from the menu, the program should display the following information about the planet: Mercury Average distance from the sun 57.9 million kilometers Mass 3.31 × 10^23kg Surface temperature –173 to 430 degrees Celsius Venus Average distance from the sun 108.2 million kilometers Mass 4.87 × 10^24kg Surface temperature 472 degrees Celsius Earth Average distance from the sun 149.6 million kilometers Mass 5.967 × 10^24kg Surface temperature –50 to 50 degrees Celsius Mars Average distance from the sun 227.9 million kilometers Mass 0.6424 × 10^24kg Surface temperature –140 to 20 degrees Celsiusarrow_forwardWrite the pseudocode for an application that will request three numbers from a user.

- Paint Job Estimator A painting company has determined that for every 115 square feet of wall space, 1 gallon of paint and 8 hours of labor will be required. The company charges $20.00 per hour for labor. Create an application that allows the user to enter the square feet of wall space to be painted and the price of the paint per gallon. The program should display the following data: • The number of gallons of paint required • The hours of labor required • The cost of the paint • The labor charges • The total cost of the paint jobarrow_forwardSoftware Sales A software company sells a package that retails for $99. Quantity discounts are given below: Quantity Discount 10–19 20% 20–49 30% 50–99 40% 100 or more 50% Design a program that asks the user to enter the number of packages purchased. The program should then display the amount of the discount (if any) and the total amount of the purchase after the discount.arrow_forwardWrite a Visual Studio 2019 Windows Forms Application that allows a user to input five daily Fahrenheit temperatures that must range from −30 to 130; if a temperature is out of range, require the user to reenter it. If no temperature is lower than any previous one, display a message Getting warmer. If every temperature is lower than the previous one, display a message Getting cooler. If the temperatures are not entered in either ascending or descending order, display a message It’s a mixed bag . Finally, display the average of the temperatures. Use the Controls that you think are best for each function. Label items appropriately, and use fonts and colors to achieve an attractive design. Include a Close button to exit the application.arrow_forward
