An object undergoes a displacement while being acted on by a constant net force directed to the north. the work done on this object by the force is positive during the displacement. which statement is necessarily true about the average velocity of the object during the displacement?

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.

i will answer your question if you answer mine
