Answer:
The ceramic glaze on a red-orange Fiestaware plate is U2O3 and contains 50.0 grams of 238U , but very little 235U. If energy is worth 12.0 cents per kW.h , what is the monetary value of the energy emitted? (These plates went out of production some 30 years ago, but are still available as collectibles.)
