The decay of the neutron is associated with a quark transformation in which a down quark is converted to an up by the weak interaction . The average lifetime of 10.3 min/0.693 = 14.9 minutes is surprisingly long for a particle decay that yields 1.29 MeV of energy.
The Stella Cherry Tree is a small self pollinating tree which produces an abundance of heart shaped, shiny, black red fruit with red flesh. It can live up to 35 years on a compact 15 foot tree.
Age Range of Trees. Trees can live, in very rare cases, up to six thousand years, although reaching that age is highly unlikely. Trees are most likely to live to old age in old-growth forests. For example, a Douglas Fir may live anywhere from 400 to 600 years in optimal conditions. As a shorter example, the average cherry tree life expectancy is around 20 years.
