Hi, I understand what you trying to say but basicly I have not been taught anything on this section. Our school gives us this assignment for us to try get the stuff ourselves. I have looked on the net for help but honestly cannot grasp the concept.

Hi, everyone. I am currently busy with an assignment at school. Am doing these questions tomorrow in school so if you can help in any way i really would be great full. Show what happens when: (1) ---> An alpha particle is given off by plutonium-239 (2) ---> A beta particle is given off by iodine-131 Suppose that carbon-14 makes up 8% of the carbon in living plants and that the half-life of Carbon is 5700 years. ---> How long will it take for the % of Carbon-14 to fall from 8% to 4% ---> How old is a specimen that has 1% carbon-14 Any help would be greatly appreciated! Thanks in advance.
