URANIUM
Studies show that the percentage weight of U 235 in natural uranium varies by as much as 0.1%, depending on the source. The A.E.C. has adopted the value of 0.711 as being their "official" percentage of U 235 in natural uranium. Natural uranium is sufficiently radioactive to expose a photographic plate in an hour or so.

What is buoyant force? (article) | Fluids | Khan Academy
Archimedes' principle is the statement that the buoyant force on an object is equal to the weight of the fluid displaced by the object. The simplicity and power of this idea is striking. If you want to know the buoyant force on an object, you only need to determine the weight of the fluid displaced by the object.
