Potassium-40 has a half-life of yr, decaying to calcium-40 and argon-40 in a ratio of 8.54 to 1. If a rock sample contained no argon when it formed a solid but now contains one argon-40 atom for every potassium-40 atom, how old is the rock?
How much Kinetic energy released and what is the daughter nucleus in the decay of nitrogen-13?
Two deuterons can fuse to form different products. Although not the most probable outcome, one possibility is helium-4 plus a gamma particle. Calculate the net energy released in this process.
The half-life is not the average lifetimeof a radioactive nucleus. We find the average lifetime by multiplyingby the probability per unit timethat the nucleus will 鈥渓ive鈥 that long, then integrating over all time.

Given initially 40mg of radium-226 (one of the decay products of uranium-238), determine,
(a) The amount that will be left after 500years.
(b) The number of 伪 particles the radium will have emitted during this time, and
(c) The amount of kinetic energy that will have been released.
(d) Find the decay rate of the radium at the end of the 500 year.
