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)
I’m pretty sure the answer would be B.

I believe this is the right answer, I hope this helps
The Triassic period is one of the geological periods and is the shortest of the Mesozoic era. Cambrian is the older era than the Triassic period.
<h3>What is Cambrian and triassic period?</h3>
The Triassic period existed 250 -200 million years ago and started after the vastest and most extreme devastation ever. It is the 1st period of the Mesozoic and is known for the movement of the Dinosaurs on the land, flying pterosaurs and swimming plesiosaurs and ichthyosaurs.
The Cambrian is the period of the Paleozoic era and is the most important period because of the appearance of many animals. In this period, the temperature raised on the planet and the ice sheets melted at a very dangerous rate leading to mass devastation.
Therefore, option A. <u>Cambrian</u> is older than the Triassic period.
