How does distance affect gravity???

no because distance is weaker than gravity

Explanation:the strenght of the gravita force between the two objects depend on two facto mass and distance the force of gravity the masses  exert on each other increases the force of gravity decreases if the distance is doubled the force of gravity is one fourth as strong as before

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.
