Can you please help me answer part C of this question in python. Include screenshots of your code for better understanding. :) (see image)

Extracted text: c) Calculate how much Radon-222 is left given a time in days, an initial amount in g, and a half-life of 3.8 days. Display the result with three (3) decimal places. d) Calculate the shear stress for a given normal stress in Ibf/in^2 that is applred to a material with a given cohesion in Ibf/in^2 and angle of internal friction in degrees. Display the result with three (3) decimal places. Each program should perform the following tasks: • Print what the program does to the screen Prompt the user to enter required data from the keyboard. Include proper units in the prompt as shown in the example output below. Get the inputs from the user and store in appropriately named variables Perform the necessary calculations Output the result to the screen with proper labels and units Example output (using inputs 20 and 5): This program calculates the voltage given resistance and current Please enter the resistance (ohms): 20 Please enter the current (amperes): 5 Voltage is 100 v As always, please include descriptive comments in your code so that someone may follow your programming logic.
