- Write a Phyton program that computes the duration of a projectile’s flight and its height above the ground when it reaches the target. As part of your solution, you should display instructions to the program user. Relevant formula: time = distancevelocity xcos (θ) height = velocity xsin x time- g x time22 use the following variables: g = gravitational constant = 32.17 = angle of elevation in radian v = velocity or the projectile velocity (ft/sec) d= distance to target t = time of flight in seconds. h = height at impact Try your program on these data sets.The following table shows the approximate speed of sound in air, water, and steel: Write a program that asks the user to enter “air”, “water”, or “steel” and the distance that a sound wave will travel in the medium. The program should then display the amount of time it will take. You can calculate the amount of time it takes sound to travel in air with the following formula: Time = Distance / 1,100 You can calculate the amount of time it takes sound to travel in water with the following formula: Time = Distance / 4,900 You can calculate the amount of time it takes sound to travel in steel with the following formula: Time = Distance / 16,400Body mass index (BMI) is a measure of health based on weight. It can be calculated by taking your weight in kilograms and dividing it by the square of your height in meters. Write a program that prompts the user to enter a weight in pounds and height in inches and displays the BMI. Note that one pound is 0.45359237 kilograms and one inch is 0.0254 meters.

The numbers a and b are known as the real part and imaginary part of the complex number, respectively.You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas:a + bi + c + di = (a + c) + (b + d)ia + bi - (c + di) = (a - c) + (b - d)i(a + bi) * (c + di) = (ac - bd) + (bc + ad)i(a+bi)/(c+di) = (ac+bd)/(c^2 +d^2) + (bc-ad)i/(c^2 +d^2)You can also obtain the absolute value for a complex number using the following formula:| a + bi | = sqrt(a^2 + b^2)(A complex number can be interpreted as a point on a plane by identifying the (a, b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in Figure 13.10.)Design a class named Complex for representing complex numbers and the methods add, subtract, multiply, divide, and abs for performing complex…
- 1. Write a program that lets the user guess whether a randomly generated integer would be even or odd. The program randomly generates an integer and divides it by 2. The integer is even if the remainder is 0, otherwise odd. The program prompts the user to enter a guess and reports whether the guess is correct or incorrect.Microwaves / Radio Waves If a scientist knows the wavelength of an electromagnetic wave she can determine what type of radiation it is.
