<p>I hear a lot of people talking about radioactive decay questions on the SAT II Physics at the beginning. I don't remember any of these. Is it possible that I skipped a whole page?</p>
<p>If you can, try to recall verbatim the first radiation question you saw on the test. The first one I remember was with 96 atoms at the beginning, 12 at the end.</p>
<p>I think the answer to that one was 1 hr and 20 minutes? Not sure though...</p>
<p>yes, it was 1hour 20minutes. it went from 96 to 12 in 4 hours. 1hr 20minutes per decay cycle.</p>
<p>yes they are right</p>
<p>i dont remember a radioactive decay question other than that one</p>
<p>what was the question about the galvanometer? i just blindly guessed lol hahah</p>
<p>Started reading it, said "F this" and moved on.</p>
<p>lol prolly what i should have done.. but if i got it right it would help, but i have a 1/5 chance lol</p>
