Summary During winter when it is very cold, typically, everyone would like to know the windchill factor, especially, before going out. Meteorologists use the following formula to compute the windchill factor, W: W = 35.74 + 0.6215 × T - 35.75 × V0.16 + 0.4275 × T × V0.16 where V is the wind speed in miles per hour and T is the temperature in degrees Fahrenheit. Instructions Write a program that prompts the user to input the wind speed in miles per hour, and the temperature in degrees Fahrenheit. The program then outputs the current temperature and the windchill factor. Your program must contain at least two functions: one to get the user input and the other to determine the windchill factor.
The Harris-Benedict equation estimates the number of calories your body needs to maintain your weight if you do no exercise. This is called your basal metabolic rate, or BMR. The calories needed for a woman to maintain her weight is: WBMR = 655 + (4.3 × weight in pounds) + (4.7 × height in inches) − (4.7× age in years) The calories needed for a man to maintain his weight is: MBMR = 66 + (6.3 × weight in pounds) + (12.9 × height in inches) − (6.8 × age in years) A typical chocolate bar will contain around 230 calories. Write a java program that allows the user to input his or her weight in pounds, height in inches, and age in years. The program should then output the number of chocolate bars that should be consumed to maintain one’s weight for both a woman and a man of the input weight, height, and age. NOTE: This is an application of a selection statement! Input Data: Use a named constant for the number of calories in a “typical chocolate bar.” Use Scanner methods to enter the…
The mitotic index is a calculated value that represents the percentage of cells in a sample that are actively dividing. It involves counting the total number of cells present including those actively dividing or those in interphase, the total number of cells that are actively dividing (not including interphase), and then calculating what percentage of the total cells are actively dividing (the percentage undergoing mitosis). The formula is: Mitotic index= # of cells in mitosis / # of cells in total x 100% Use this formula to calculate the mitotic index for the diagram seen in Question 5. Show your calculations (you can use * for multiplication and / for division if you prefer) and indicate your final answer as a percentage rounded to the nearest tenth of a percentage (1 decimal place). Note: The mitotic index seen in this simulation is much higher than you would see in a real tissue sample. The sample was simulated this way so that the counting and calculations would be easier…
Science: wind-chill temperature. How cold is it outside? The temperature alone is not enough to provide the answer. Other factors including wind speed, relative humidity, and sunshine play important roles in determining coldness outside. In 2001, the National Weather Service (NWS) implemented the new wind-chill temperature to measure the coldness using temperature and wind speed. The formula is given as follows: ??? = 35.74 + 0.6215?? − 35.75?0.16 + 0.4275??? 0.16 Where ?? is the outside temperature measured in degrees Celsius and ? is the speed measured in kmper hour. ??? is the wind-chill temperature.

You can calculate the area of a triangle if you know the lengths of all three sides, using a formula that has been known for nearly 2000 years. It is called "Heron's Formula". Heron's formula uses the following two steps to calculate the area of a triangle. Step 1: Calculate "s" (half of the triangles perimeter): S= Step 2: Calculate Area: A = √s(sa)(sb)(sc) By using Heron's formula, write the definition of the function area_of_triangle so that it can work in conjunction with the following source code. #include #include int main (void) { double a, b, c, area; printf("Enter the sides of triangle\n"); scanf("%lf%lf%lf", &a, &b, &c); a+b+c 2 area = area_of_triangle (a, b, c); printf ("Area of triangle = %.21f\n", area); return 0; } You can use sqrt() from math.h header file. Its prototype is: double sqrt (double x); A sample run of this program is shown in the following figure. Enter the sides of triangle 4.0 5.0 6.0 Area of triangle = 9.92
Using Heron's formula, you can calculate the area of a triangle if you know the lengths of all three sides. Given the length of each side of a triangle as input, calculate the area of the triangle using Heron's formula as follows: s = half of the triangle's perimeter area = the square root of s(s-a)(s-b)(s-c), where a, b, and c are each sides of the triangle. Hint: Use the sqrt() function from the math module to calculate the square root. Output the floating-point value of the area with three digits after the decimal point, which can be achieved as follows:print('The area of the triangle is: {:.3f}'.format(your_value)) Ex: If the input for a, b, and c is: 3.0 4.0 5.0 the output is: The area of the triangle is: 6.000
Engineers use both English and SI (Système International d’Unités) units on a regular basis. Some fields use primarily one or the other, but many combine the two systems. For example, the rate of energy input to a steam power plant from burning fossil fuels is usually measured in Btu/hour. However, the electricity produced by the same plant is usually measured in joules/s (watts). Automobile engines, by contrast, are often rated in horsepower or in ft lbf/s. Here are some conversion factors relating these different power measurements: a) Generate a table of conversions from kW to hp. The table should start at 0 kW and end at 15 kW. Use the input function to let the user define the increment between table entries. Use disp and fprintf to create a table with a title, column headings, and appropriate spacing. The output should look like: kW hP 0.0 0.00 2.5 3.35 5.0. 6.70 7.5 10.06 10.0 13.41 12.5…

The Ibra College of Technology has an automated system that calculates the overall grade for each student of a class. The system gets to know the number of students in a class from the teacher. For each student, it asks their name and the number of subjects they took. For each subject, they ask the score. They then take the average of the scores of all the subjects, divide it by 10 and display the name and GPA for each student. Read the number of students in a class, the name and the number of subjects for each student. Then read the scores of each subject for each student, calculate the GPA by averaging the scores and dividing the average by 10. Finally, display the name and GPA for each student.

The (x, y) coordinates of the hand at the top of a robot arm are given by: x = L, cos(8,) + L, cos(8, + 0,) y = L, sin(0,) + L,sin(8, + 02) Where Li and L2 are the distances of the parts of the arm from the shoulder to the elbow and from the elbow to the hand, 01 and 02 are the angles that these parts make with the x-axis. These angles can be expressed as: 0,(t) = a,t5 + a,t“ + azt³ 02(t) = bịt5 + b;t + b3t³ where t is the time. We assume that the arm starts to move at t= 0s and stops at tf=2s. The conditions that the angular position G1(t), angular velocity and angular acceleration should meet at the final time tf = 2 (in sec) are expressed in the following matrix form and allow us to obtain the coefficients a1, az and a3: 25 24 23 3x22||a2 = [az.

(Mechanics) The deflection at any point along the centerline of a cantilevered beam, such as the one used for a balcony (see Figure 5.15), when a load is distributed evenly along the beam is given by this formula: d=wx224EI(x2+6l24lx) d is the deflection at location x (ft). xisthedistancefromthesecuredend( ft).wistheweightplacedattheendofthebeam( lbs/ft).listhebeamlength( ft). Eisthemodulesofelasticity( lbs/f t 2 ).Iisthesecondmomentofinertia( f t 4 ). For the beam shown in Figure 5.15, the second moment of inertia is determined as follows: l=bh312 b is the beam’s base. h is the beam’s height. Using these formulas, write, compile, and run a C++ program that determines and displays a table of the deflection for a cantilevered pine beam at half-foot increments along its length, using the following data: w=200lbs/ftl=3ftE=187.2106lb/ft2b=.2fth=.3ft
