The average binding energy per nucleon is the best parameter to use in determining whether a given nucleus is likely to undergo fission
What will be an ideal response?
That depends on how the statement is meant. Fission will only occur for mass
numbers greater than about 56, for which the average binding energy per nucleon is less
than that of nuclei near A = 56.

Which of the following is the best description of how a fluorescent bulb works?
A) Electrons flowing through the bulb get heated up within the bulb, and these electrons emit light. B) A gas flows from one end of the bulb to the other, and the gas atoms are energized by the electric field which causes the atoms to emit light. C) Electrons flow through the bulb, causing a chemical reaction in the gas atoms inside the bulb, which causes these atoms to emit light. D) A gas fills the bulb and when the gas atoms strike the walls of the bulb the material in the wall emits light. E) Electrons flow from one end of the bulb to the other, hitting gas atoms and causing them to emit light.
