This lesson is part of the following series:

AP Physics Homework Examples – Full Course (50 lessons, $29.70)
Modern Physics – AP Physics Homework Examples (5 lessons, $3.96)

Advanced Placement (AP) Physics teachers explain how to complete homework problems in "Nuclear Physics." Each of the 3 tutorials explains a different problem or problems in detail, complete with equations, diagrams, and hints for successful Physics problem solving. Specific topics included in this lesson are: radioactive decay, half life of radioactive materials, alpha, beta, and gamma decay, positrons and neutrinos, and radioactive decay reactions. PDF files of the problems and solutions for the tutorials in this lesson are also included.
Applicable to AP Physics or Non-Calculus College Physics (and some lower level physics.)

Tutorials included in this lesson:
27-1: Half Life
27-2: Half Life (II)
27-3: Radioactive Decay Reactions

The tutorials in this lesson are also part of the following series:

- "AP Physics Modern Physics Homework Examples" which includes 5 lessons (16 tutorials) in quantum physics, atomic physics, and nuclear physics.

- "AP Physics Homework Examples – Full Course" which includes 50 lessons (230 tutorials) in all topics of Physics: Mechanics, Fluids, and Thermal Physics, Electricity and Magnetism, Waves and Optics, and Modern Physics.

Nuclear Physics
(Part A):

27-1: Half Life (at 0:10)
A graph of activity versus time for a particular radioactive isotope is shown. Determine an experimental value of the half life of the isotope.

27-2: Half Life (II) (at 1:42)
A 1.49 μg sample of pure Nitrogen-13 has an initial activity of 8.00 x 1013 decays per sec. The half life of Nitrogen-13 is 10.0 minutes. Determine the mass and activity of the sample after 1 hour.

27-3: Radioactive Decay Reactions (at 5:08)
Use a periodic table to write equations for the following radioactivity decay reactions:
a) Alpha decay of Thorium 228
b) Negative beta decay of Potassium 40
c) Positive beta decay of Carbon 11
d) Gamma decay of Thallium 208
