The human body produces motion by changing chemical energy in food into mechanical energy for the moving muscles we know their energy is conserved during energy transformations which best describes what happened to enter the total amount of energy during transformation

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.
