Hace 1 día · Category. v. t. e. Nuclear fusion is a reaction in which two or more atomic nuclei, usually deuterium and tritium (hydrogen isotopes ), combine to form one or more different atomic nuclei and subatomic particles ( neutrons or protons ). The difference in mass between the reactants and products is manifested as either the release or absorption ...
Hace 3 días · Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions.

Many physical processes are related to temperature; some of them are given below: the physical properties of materials including the phase (solid, liquid, gaseous or plasma), density, solubility, vapor pressure, electrical conductivity, hardness, wear resistance, thermal conductivity, corrosion resistance, strength
Hace 6 días · Diver looking at a shipwreck in the Caribbean Sea. Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance.

Hace 5 días · The pressure field is obtained from the velocity field as = ‖ ‖ / (where and are reference values for the pressure and density fields respectively). Since both the solutions belong to the class of Beltrami flow , the vorticity field is parallel to the velocity and, for the case with positive helicity, is given by ω = 3 k u {\displaystyle \omega ={\sqrt {3}}\,k\,{\boldsymbol {u}}} .
