Question: The _Galileo_ space probe was launched on its long journey past several planets in 1989, with an ultimate goal of Jupiter. Its power source is 11.0 kg of {}^{238}\text{Pu} , a by-product of nuclear weapons plutonium production. Electrical energy is generated thermoelectrically from the heat produced when the 5.59-MeV \text{α} particles emitted in each decay crash to a halt inside the plutonium and its shielding. The half-life of {}^{238}\text{Pu} is 87.7 years. (a) What was the original activity of the {}^{238}\text{Pu} in becquerel? (b) What power was emitted in kilowatts? (c) What power was emitted 12.0 y after launch? You may neglect any extra energy from daughter nuclides and any losses from escaping \text{γ} rays.
