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

- A Python Programming in Physics and Materials Science. In physics, chemistry and materials science, percolation refers to the movement and filtering of fluids through porous materials.(Wikipedia.org). Consider a simplified model below. Imagine, this is a filter or maybe some layers of stones such that when a certain amount of fluid is put on top, it will reach the bottom only if there is a direct passage. In this case, the blue squares serve as the porous materials or the holes where fluid may pass. Your task is to simulate this simple percolation by representing them in a 2-dimensional array. The input would be in a string, while the output would either be yes or no to indicate whether the fluid can pass through the filter or not. Example: Input: “1,0,0,0,0;0,1,0,0,0;0,1,0,0,0;0,0,1,0,0;0,0,0,1,0” Output: Yes Note: It should also work with these two inputs: “1” -> Yes “0” -> Noarrow_forwardWrite a program that inputs a number and checks whether it is a perfect number or not. A perfect number is the number that is numerically equal to the sum of its divisors. For example, 6 is a perfect number because the divisors of 6 are 1, 2, 3 and 1+2+3=6arrow_forwardA robot is initially located at position (0, 0) in a grid [−5, 5] × [−5, 5]. The robot can move randomly in any of the directions: up, down, left, right. The robot can only move one step at a time. For each move, print the direction of the move and the current position of the robot. If the robot makes a circle, which means it moves back to the original place, print “Back to the origin!” to the console and stop the program. If it reaches the boundary of the grid, print “Hit the boundary!” to the console and stop the program. A successful run of your code may look like: Down (0,-1) Down (0,-2) Up (0,-1) Left (-1,-1) Left (-2,-1) Up (-2,0) Left (-3,0) Left (-4,0) Left (-5,0) Hit the boundary! or Left (-1,0) Down (-1,-1) Right (0,-1) Up (0,0) Back to the origin! Instructions: This program is to give you practice using the control flow, the random number generator, and output formatting. You may not use stdafx.h. Include header comments. Include <iomanip> to format your output. Name…arrow_forward
- Write a program that computes the theoretical flame temperature when a mixture of methane, propane, n-butane, and n-pentane (0% to 100& methane in 5% increments; 0 to 100 mol% propane in 5% increments; 0% to 100% mole n-butane in 5% increments) at 25°C is burned with excess air (0% to 100% excess in 5% increments) preheated to preheated to (50°C to 200°C in 10°C increments)arrow_forward***Microsoft Visual Studios (C++)*** Write a program that given two coordinate pairs and a third single coordinate will linearly interpolate or extrapolate the third second coordinate. For example, let's say at 50 degrees Celsius the length of a metal rod is 5.4 cm and at 60 degrees Celsius the length is 5.5cm. I can interpolate the length at 53 degrees Celsius by doing 5.4cm + 3*(.1/10)=5.43cm. Your program does not need to continuously run, but should prompt the user for two coordinate pairs, the third first coordinate and return the extrapolated or interpolated third second coordinate.arrow_forwardWrite a program to calculate the surface area and volume of a square pyramid. A square pyramid has a base that is square and all triangle faces are congruent isosceles triangles. (An isosceles triangle is a triangle in which two of the sides are equal. Length of the base: a Height of the pyramid: h Volume = a2h/3 Slant height, s = sqrt(h2 + (a/2)2) This is the Pythagorean Theorem part. Area of one pyramid side = s*a/2 For this program you are to determine two things about a square pyramid. 1) the surface area of the four sides. 2) the volume. Do not include surface area of the base. Test case 1: Height: 5.0' Base: 2.5' Test case 2: Height 2.5 Base: 4.3' The program asks the user to enter the pyramid height (in feet) and length of the base (in feet). Your program will need to determine surface area, and volume by using pythagorean theorem. Your output should neatly show the height, base, total surface area, and volume of the pyramid using 33 decimal place of…arrow_forward

- A very known application in natural language processing is to extract information from a given text. In this lab, you will be able to extract some emotions (Sad and Happy) from a given string and calculate the score of each emotion. You will be given below the words that express sadness, anger, and happiness. For each word, you will be given weight as well, so that when you are calculating for example the score for sadness in the text (string), you can use this formula:arrow_forwardWrite a program that translates a letter grade into a number grade. Letter grades are A, B, C, D, and E, possibly followed by + or -. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or F-. A + increases the numeric value by O.3, a – decreases it by 0.3. However, an A+ has value 4.0. Enter a letter grade: B- The numeric value is 2.7.arrow_forwardThe Fibonacci sequence is listed below: The first and second numbers both start at 1. After that, each number in the series is the sum of the two preceding numbers. Here is an example: 1, 1, 2, 3, 5, 8, 13, 21, ... If F(n) is the nth value in the sequence, then this definition can be expressed as F(1) = 1 F(2) = 1 F(3) = 2 F(4) = 3 F(5) = 5 F(6) = 8 F(7) = 13 F(8) = 21 F(n) = F(n - 1) + F(n - 2) for n > 2 Example: Given n with a value of 4F(4) = F(4-1) + F(4-2)F(4) = F(3) + F(2)F(4) = 2 + 1F(4) = 3 The value of F at position n is defined using the value of F at two smaller positions. Using the definition of the Fibonacci sequence, determine the value of F(10) by using the formula and the sequence. Show the terms in the Fibonacci sequence and show your work for the formula.arrow_forward
