A physical model is defined as a model which represents how atoms are bonded together and structure of a molecule.
Physical model shows the three dimensional structure of a molecule. Physical models helps to easily understand and visualize the configuration, single bonds, double bonds and total atoms within a molecule.
Thus, we can conclude that given structure of carbonic acid best describes a physical model.
Nuclear fission is the process of which a large nucleus splits into two smaller nuclei with the release of energy and neutron. In simpler words, nuclear fission is the process in which a nucleus is split into two smaller fragments or pieces (nuclei) and so energy and neutrons are released. The resulting pieces of this fission process have less combined mass than the original piece (nucleus) and the missing was is converted into nuclear energy.
