When traveling through a gas, the speed of sound depends primarily on the density of themedium. The less dense the medium, the faster the speed will be. The following tableshows the approximate speed of sound at 0 degree celsius, measured in meters per second,when traveling through carbon dioxide, air, helium, and hydrogen.MediumSpeed (meters per sec.)Carbon dioxide258.0Air331.5Helium972.0Hydrogen1270.0Write a program that displays a menu allowing the user to select one of these 4 gases. Aftera valid selection has been made, the program should ask the user to enter the number ofseconds (0 to 30) it took for the sound to travel in this medium from its source to thelocation at which it was detected. The program should then report how far away (inmeters) the source of the sound was from the detection location.

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 (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.

Background and formula: Ellipse has two types of axis - Major Axis and Minor Axis. The longest chord of the ellipse is the major axis. The perpendicular chord to the major axis is the minor axis, which bisects the major axis at the center as shown in Figure 1. Ellipse is different with circle which has only one radius. There is no simple formula to calculate the exact or accurate value of perimeter of an ellipse. Therefore, we use approximation formulas to calculate the approximate value of an ellipse's perimeter. One of the approximation methods is called Ramanujan Formula as follows: p zn[3(a+b) – Г(За + b) (а + зь)| where a is the semi major axis and b is the semi minor axis of the ellipse, respectively, as shown in Figure 1. be major axis Figure 1.

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 average daily temperature for an area can be approximated using the following equation: T = Tmean + (Tpeak – Tmean) cos (@(t – tpeak) %3D where Tmean is the mean temperature over a year, Tpeak is the highest daily mean temperature, w is the frequency of annual variation, tpeak is the day that the peak temperature occurs, and t represents the days 33 to 400 (inclusive, increments of 1). w has the value 2n/365. A. Write a function that takes Tpeak, tpeak, Tmean and t as inputs (4 inputs) and outputs the following 3 return values: The temperature for for each day The minimum temperature for the year The day with the minimum temperature B. In 2008, Melbourne's temperature statistics were: Tpeak = 25.9°C, tpeak = 13 and Tmean = 19.8°C Use the function you wrote in part A to plot on a single figure the following: Temperature for every day of the year as a black continuous line Use fprintf() to print the minimum temperature and the day it occurred. Then use a red asterisk to mark it on…
One way to determine how healthy a person is by measuring the body fat of the person. The formulas to determine the body fat for female and male are as follows: Body fat formula for women: A1 = (body weight x 0.732) + 8.987 A2 = wrist measurement (at fullest point)/3.140 A3 = waist measurement (at navel) x 0.157 A4 = hip measurement (at fullest point) x 0.249 A6 = forearm measurement (at fullest point) x 0.434 B = A1 + A2 A3 A4 + A5 Body fat = body weight - B Body fat percentage = body fat x 100/body weight Body fat formula for men: A1 = (Body weight x 1.082) + 94.42 A2 = wrist measurement x 4.15 B = A1 A2 Body fat = body weight B Body fat percentage = body fat x 100/body weight Write a program to calculate the body fat of a person.

Section: FactThyroid function is measured using a factor called TSH, which stands for thyroid-stimulatinghormone. A TSH test is a blood test that measures this hormone. TSH normal values are 0.5 to 5.0mIU/L. If TSH is over 5.0 thyroid is underactive. On the other hand, if TSH is less than 0.5 thyroid isoveractive.
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…
