- Write a program that computes the theoretical flame temperature when a mixture of methane, propane, n-butane, and n-pentane (0% to 100& methane in 5% increments; 0 to 100 mol% propane in 5% increments; 0% to 100% mole n-butane in 5% increments) at 25°C is burned with excess air (0% to 100% excess in 5% increments) preheated to preheated to (50°C to 200°C in 10°C increments)arrow_forwardWrite a program that calculates the potential energy of 3 charges q1 = 1, q2 = 2, q3 = 3located at points (1, 2, 3), (3, −4, −5), and (−4, 2, −6) respectively. The units are coulombs forcharge and meters for coordinates. The energy is given by the expressionarrow_forwardThe equation of a straight line is written as y = mx + b where m is the slope of the line and b is the value of y when x = 0. If there are two coordinate points of the line are given, then it is very easy to compute the line equation. Also you can find the distance between two points. Problem: Write a program to compute lines equation for a set of lines. The number of lines is read from the user. Each line is computed by generating two points randomly using Point2D API. In addition, distance between two points is computed. The program should display a table which include all information about each line. See sample runs below. Take into consideration: 1. Number of generated lines should be greater than zero. 2. Two point objects are constructed only once. Then just update the location of two points for each line using Point2D API methods. 3. x and y values of each point are generated randomly to be less than 100 and greater than 0. 4. Compute the distance between two points using…arrow_forward
- In Python A soup company is interested in finding out how much of their soup will go into various sized cans. The user will input the diameter of the can end, and the height of the can. The volume of a cylinder is the well known formula: volume = area of the ends * height of cylinder. The twist is that a can of soup can not be completely filled to the top; only 95% of the volume can be filled with soup; the remaining 5% must remain empty to allow for expansion. NOTE: when computing the area, use pi to at least 5 significant digits (eg, 3.14159) or use the constant math.pi. You should define a function named soup_volume which takes two parameters, the diameter of the can in cm, and the height of the can in cm, in that order. The function should return a float value, which is the volume of soup that the can is able to hold. The function should not round the value, but when printing the value in the main program, format it to show only 2 decimal places.

- Write a program that reads an integer and displays its first five multiples. For example, if the input integer is 10, the output should be as follows: 10, 20, 30, 40, 50.arrow_forwardA bullet train slows from a speed of 200 mi/hr to 150 mi/hr in one minute. Write a computer program that calculates the bullet train’s constant rate of acceleration and determines how long the bullet train will take to come to rest, given an initial speed of 200 mi/hr. (Hint: Use the equation a = vf - vi t where a is acceleration, t is time interval, vi is initial velocity, and vf is final velocity.) Write and call a function that displays instructions to the program user and a function that computes a, given t, vf, and vi. using c programming languagearrow_forwardWrite a program that reads from the user a character ('q' or 'c'). If the character is 'c', the program reads from the user the radius rof a circle and prints its area. • If the user enters 'q', the program asks the user to enter the length and width of a quadrilateral. We assume the quadrilateral is either a square or rectangle. You should print if the quadrilateral is square or rectangle. • Otherwise, it prints "Wrong character" PS: Use the following formulas: area of circle=3.14*r Sample Run1: Enter a character (q or c): q Enter the Length and Width: 80 150 |It is a rectangle Sample Run2: Enter a character (q or c): q Enter the Length and Width: 80 80 It is a square Sample Run3: Enter a character (q or c): c Enter the radius: 2 The area of the circle is 12.56 Sample Run4: Enter a character (q or c): d Wrong characterarrow_forward
