The nucleus contains protons and neutrons. being positively charged, the protons repel each other. the nucleus should fly apart due to the repulsive force. yet, the nuclei of most atoms are stable - explain. (5 points)

this is due to the existence of other forces called the strong nuclear forces that overcomes the repulsion forces between the protons and keeps the nucleons holding to each other also there is a type of energy that is called the nuclear binding energy and this energy also works on binding the components of the nucleus together

that would be b i just took the test : )

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
