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.
Not long. It depends on type of plum tree, how much water it gets, type of soil, sunlight, pruning, those sort of things. A purple plum, Prunus cerasifera, can live for as little as 20 years and it will have got to full size long before that. 1 person found this useful.
