It increases by a factor of 4. It is not impacted by the change in wind speed. It increases by a factor of 2. It decreases by a factor of 4. It decreases by a factor of 2. The atom is __________. the structure of matter that is defined by the number of electrons is contains the smallest unit of matter that retains the chemical properties of an element the smallest unit of matter; it is indivisible a grouping of neutrons Solar energy is quite compatible for a major part of the United States because our major energy needs are for _________ energy. potential mechanical thermal kinetic electrical Why can a nuclear reaction be self-sustaining? Each reaction consumes exactly one neutron, which initiates more than one additional reaction. Each reaction consumes enough neutrons to initiate more than one additional reaction. Each reaction produces enough neutrons to initiate more than one additional reaction. Each reaction produces exactly one neutron, which initiates more than one additional reaction. Which of the following type of water-based power receives most of its energy from the moon?
