The half-life of caron is 5730 years. How much carbon will be left after 22920 years?
Correct answer: B. 1/16
- A. 1/32
- B. 1/16
- C. 1/64
- D. 1/4
Explanation
Amount of Carbon decayed= 22920/5730=4 half lifes passed. The half lifes left are ½ *½ * ½* ½ = 1/16th.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
