Identify the number with the correct number of significant figures for each step of the calculation and for the final answer. Note that 2 is an exact number. y equals 2.10 StartBracket 9.0 plus 2 times 35.35 EndBracket. 2 (35.35) =

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.
