The half life of uranium is not one day.
For an isotope with the half life or one day, after 3 days: the quantity remained is 12,5 %.
12.5 %
No, uranium-238 has a long half-life of about 4.5 billion years. It is a naturally occurring isotope that is commonly found in nature. Shorter-lived isotopes, such as radon-222 or polonium-214, have much shorter half-lives.
Since that is close to its half-life, about half the original quantity will be left.
2 thirds would be left
The halflife of 235U is 704 million years. 1420 million years is approximately two halflives, so about 24.7% would be remaining.
3,375 days
If a solid piece of uranium goes through a process like fission, the amount of uranium left would depend on the specific fission reactions that occur. During fission, uranium atoms split into smaller atoms, releasing energy and more neutrons which can continue the reaction. Some uranium atoms may be converted into other elements through the fission process, so the amount of remaining uranium would be less than the original piece.
You will have 80 dollars left.
one third
None. A pellet of uranium contains uranium, not coal.
After spending one third of your money, you would have 18 units of money left (27 - 9 = 18).
Uranium is not used at home.
