Which of the following would have the smallest gravitational attraction between the two masses?

Distance= 100,000 km

   Mass= 15 million kg        Mass= 5 million kg

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.

it breaks and dirupture other materials and other sencews from the bottom
