Helppp Energy and Matter 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 it is
important to control the rate of the chain reaction.

Select the correct answer. you have a nightlight plugged into an outlet in the hallway, which uses 3.5 watts when plugged in. if the house circuit provides 120.0 volts, what is the current through this bulb?

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
