The following formula can be used to determine the distance an object falls due togravity in a specific time period:d =112 gt2The variables in the formula are as follows:• d is the distance in meters,• g is 9.8,• and tis the time in seconds that the object has been falling.Write a function named fall i ngDi stance that accepts an object's falling time (in seconds)as an argument. The function should return the distance, in meters, that the object hasfallen during that time interval. Write a program that demonstrates the function by callingit in a loop that passes the values 1 through 10 as arguments and displays the return value.

Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)
(Physics) Buoyancy is the upward force a liquid exerts on a submerged object, as shown in Figure 6.9. The buoyancy force is given by this formula: B=pgV Bisthebuoyancyforce( lbforN).isthefluiddensity( slug/f t 3 orkg/ m 3 ).gistheaccelerationcausedbygravity( 32.2ft/se c 2 or9.8m/ s 2 ).Vistheobjectsvolume( f t 3 or m 3 ). a. Using this formula, write a function named buoyantForce(double ro, double vol, int units) that accepts a fluid density, the volume of an object placed in the fluid, and the units to be used(1=U.S.Customaryunits,2=metricunits), and returns the buoyancy force exerted on the object. b. Include the function written for Exercise 6a in a working C++ program, and use your program to complete the following chart:
(Numerical) Heron’s formula for the area, A, of a triangle with sides of length a, b, and c is A=s(sa)(sb)(sc) where s=(a+b+c)2 Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of sand[s(sa)(sb)(sc)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A=1. The value of A should be returned by the function.
In physics, an object that is in motion is said to have kinetic energy. The following formula can be used to determine a moving object’s kinetic energy:KE=12mv2The variables in the formula are as follows: KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second. Write a function named kinetic_energy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The function should return the amount of kinetic energy that the object has. Write a program that asks the user to enter values for mass andvelocity, then calls the kinetic_energy function to get the object’s kinetic energy.

Write a function that uses the one mentioned above so that it prints “Go to work!” if the person is not old and “You deserved to have a long vacation” otherwise. Your function must also accept the age as its argument. My code def funct2(age): flag = old_person(age) if(flag): print("You deserved to have a long vacation") else: print("Go to work!")

This question has 2 parts, in part A you will write a function and part B need to implement the function Part A - Write a function called getDistance. This function will have 2 parameters: first is the speed of the object in miles per hour the second is time traveled in hours. The function will return the distance traveld by multiplying the speed by the time passed by parameter. Part B will be a small program that will input the speed and time traveled by 2 vehicles. It will then print which vehicle traveld the furthest and must utilize the function written in part A appropriately. Complete the starter file below (copy and paste into your answer). #write your function here def main(): vehicle1_speed = int(input("Enter the speed of vehicle 1: ")) vehicle1_time = int(input("Enter the time vehicle 1 has traveled: ")) vehicle2_speed = int(input("Enter the speed of vehicle 2: ")) vehicle2_time = int(input("Enter the time vehicle 2 has traveled: "))…
fast please in pyth 10. Write a complete function. The name of the function is priceGuide, it has a single input parameter called avgPrice, and it has no return. The function is used to determine how expensive restaurants are, based on their average meal price (you can assume that the price is always larger than zero). If the average price is $10 or less, print the message “Inexpensive”. If the price is more than $10 but less than or equal to $30, print the message “Moderate”. If the price is more than $30, print the message “Pricey”. 9. Write a for loop to print all the even numbers contained in the range of 2 to 20, inclusive.
This is the second lab for the Unit 4 zyBooks materials. Coding hints: def lapstomiles(user_laps): return user_laps / 4.00 #Please note that one mile is equal to four laps … print(f'{num_miles:.2f}') #We are formatting the laps into two decimal places. One lap around a standard high-school running track is exactly 0.25 miles. Define a function named laps_to_miles that takes a number of laps as a parameter, and returns the number of miles. Then, write a main program that takes a number of laps as an input, calls function laps_to_miles() to calculate the number of miles, and outputs the number of miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print(f'{your_value:.2f}') Ex: If the input is: 7.6 the output is: 1.90 Ex: If the input is: 2.2 the output is: 0.55 The program must define and call the following function:def laps_to_miles(user_laps) # Define your function here if __name__ == '__main__': user_laps =…
