Unlike many modern exams, basic calculators were permitted during the 1984 administration. 1984 ap physics b free response
Determine the time at which half of the initial nuclei remain for Isotope 1 and Isotope 2. Decay Rate: years, the isotope with the steeper slope (negative) on the graph is decaying at a greater rate ( moving in a vertical circle
Rumors (often cited on teacher forums like the College Board AP Physics Community) suggest that a raw score of roughly 55% to 65% could earn a 5 in 1984. This was not because students were weaker, but because the problems were longer and more error-prone. One algebraic slip in part (a) cascaded through parts (b), (c), and (d). Decay Rate: years, the isotope with the steeper
Using a graph of remaining nuclei over time for two isotopes: Half-life:
