106.
¹⁴C decays with a half-life of about 5500 years.

(a) What would you guess to be the nature of the decay, and what are the final products? Very briefly explain.

(b) If no more
¹⁴C enters biological systems after their death, estimate the age of the remains of a tree whose radioactivity (decays/sec) of the type given in (a) is 1/3 of that of a comparable but relatively young tree.
