Answer:
B. are openings in the earth surface
The energy released by 1 atom of Uranium is Q=185.*10^6-25.
The energy needed for U.S. that I will name Q2, in eV is: 1*10^19J* (1eV/(1.602*10^-19))=6.2422*10^37eV
Q=mc^2
Q2=mc^2
m is the mass of Uranium in kg that we calculated at 3.90*10^-25. We need to fund m2 because that is the unknown mass in the equation for Q2 to give us the energy for the U.S. and remember, Q is the energy that 1 atom of Uranium gives out which is why we took a ratio.
m2=Q2/Q*m=1.3*10^5 kg (final answer)
