3. Exercise 
- Enter 0.4 for the decay constant!
 - Before you start the simulation answer the first question. 
 - Run one step of simulation and observe how many nuclei have been decayed! 
 - Clear and repeat it several times! 
  
Questions: 1) What activity do you expect from this radioactive material? (Hint: remember the following equation:   
 2) What might be the reason that you do not get back the expected value?  3) If you repeat the simulation several times, which is the interval where you get values?      |   If you would like to see the simulation in full screen, please click here.    |
