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.
Size. The live oak can live for up to 300 years, reach 80 feet in height and grow canopies up to 100 feet wide. Most specimens will average only about 40 to 60 feet in height and about 60 to 80 feet wide, but these dimensions can still make planting difficult.
