In fluid statics, capillary pressure is the pressure between two immiscible fluids in a thin tube (see capillary), resulting from the interactions of forces between the fluids and solid walls of the tube.
The elements formed in these stages range from oxygen through to iron. During a supernova, the star releases very large amounts of energy as well as neutrons, which allows elements heavier than iron, such as uranium and gold, to be produced.In the supernova explosion, all of these elements are expelled out into space.he elements formed in these stages range from oxygen through to iron.

Best Answer: A. Plutonium The world's first nuclear explosion was achieved with plutonium, a man-made element produced in nuclear reactors. Plutonium is created when an atom of uranium-238 absorbs a neutron and becomes plutonium-239.The reactor generates the neutrons in a controlled chain reaction.tomic bombs have either Uranium-235 or Plutonium-239 at their core. The Hiroshima bomb, a gun-type bomb called Little Boy, was made with uranium-235 The Nagasaki bomb, called Fat Man, was implosion-type devices made primarily of plutonium-239, a synthetic element.[.
