electric power plants that use nuclear fission reactions rely on a controlled self sustaining chain reaction of splitting atoms. by examining the diagram for nuclear fission, explain how a chain reaction might occur. explain why is it important to control the rate of the chain reaction

While unproven, it uses facts to support part of a conclusion. it is still factual and has predictive power, however.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
