Which of the following procedures will double the force on two point charges? a. halving the distance between the charges b. doubling the magnitude of one charge c. halving the magnitude of one charge d. doubling the distance between the charges

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.

the answer is to check all of them! they all apply well at least i think so!

truck y has a greater velocity than truck x.
