Moderen Physics Quiz Explanation is given below
- Neutrons and protons are together called Nucleons.
They reside inside the nucleus. They represent the mass
number of a nucleus. The number of protons represents
the atomic number of a nucleus.
- Gravitational force is the weakest interaction among
the four fundamental forces in nature. Strong nuclear
force is the strongest force among them as it is the
reason the positively charged protons, which must be
repelling each other in general, are held together tightly
inside a nucleus.
- The graph is a straight line as the radius of a nucleus
is constant for all nuclei, irrespective of their mass
- Gamma rays are electromagnetic waves of the
shortest wavelength. It mainly arises from the radioactive
disintegration of nuclei in an excited state to get to the
- An antineutrino is released during the process of
transformation of a neutron into a proton and an electron.
