Concept explainers
Radioactive decay of radioactive materials can be modeled by the equation A = A0e−t(log 2/h), where A is the amount of the material at time t, A0 is the amount at time 0, and h is the half-life.
Technetium-99 is a radioisotope that is used in imaging of the brain. It has a half-life of 6 hours. Your

- Write a computer program for calculating carburization heat treatments. The program should ask the user to provide an input for the carbon concentration at the surface (cs), and the concentration of carbon in the bulk (c0).arrow_forwardWrite a program that calculates the equivalent resistance of a circuit. n electrical resistors with resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied across each. Their equivalent resistance Reg is related to the values R1, R2, ..., Rn by: 1 1 1 1 + +...+ R R R, R. "eq Write a program that prompts the user to enter the resistance of n resistors. The user should be prompted continuously by using a while loop until a zero or negative value is entered (the program should count the number of resistors n entered by the user and store the values in an array). Use another separate loop to print the resistance values entered by the user and the equivalent resistance Reg. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.arrow_forwardIn various applications, you are often asked to compute the mean and standard deviation of data. The mean is simply the average of the numbers. The standard deviation is a statistic that tells you how tightly all the various data are clustered around the mean in a set of data. For example, what is the average age of the students in a class? How close are the ages? If all the students are the same age, the deviation is 0. Write a program that prompts the user to enter any number of values into a double array, and then calculates and displays the mean and standard deviations of these numbers using the following formulas: (z - mean) z+z3+ *** +zn deviation = mean = n-1 Required Methods You must write your program so that the following methods are defined/implemented and used (called): • /* Compute the deviation of double values */ public static double deviation (double[] x) • /* Compute the mean of an array of double values */ public static double mean (double[] x) Sample Run (user input…arrow_forward

- Make a C program: After beating the record for the quickest time to beat a Hydra, Cody became a local celebrity in Codeville. He decided to hold fan meet-ups every weekend. When he arrived at the first fan meeting, Cody was shocked to see so many people. He didn't know how to give all of these people their equal share of autographs and photos, so he decided to come up with an algorithm. First, he would count the number of fans (n) and determine if the number is even or odd. If they are even he would give n * 2 photos and signatures that day but if it is odd he would give out (n * 2) + 1. Input the number of fans and have Cody print the number of autographs and signatures he will give.arrow_forwardThe unit of convection current density is * O Ampere per Meter O Ampere O Volt per Meter O Ampere per Square Meterarrow_forward(Program) Write a program to simulate the rolling of two dice. If the total of the two dice is 7 or 11, you win; otherwise, you lose. Embellish this program as much as you like with betting, different odds, different combinations for win or lose, stopping play when you have no money left or reach the house limit, displaying the dice, and so forth. (Hint: Calculate the dots showing on each die with theexpressiondots=(int)(6.0randomnumber+1), where random number is between 0 and 1.)arrow_forward

The formula for computing the area of a regular polygon is Area = ( n * s2 ) / (4 * tan( π/n) Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area.arrow_forwardThe civil engineering department has asked you to write a program to compare three different designs of water towers shown in the diagrams below. The water towers are a cylinder topped with a half sphere. The engineers want to find the design that has the highest volume. The dimensions of the three designs are as follows: Design 1: Sphere Radius 98 feet Cylinder Radius 98 feet Height 102 feet Design 2: Sphere Radius 90 feet Cylinder Radius 90 feet Height 120 feet Design 3: Sphere Radius 100 feet Cylinder Radius 100 feet Height 98 feet Write two functions that will calculate the volume of a sphere and a cylinder respectively. Then, use these functions to write a program that will find the design with the largest volume. Hint: Remember that the tower only consists of a half sphere. Solve in Python Pleasearrow_forward
