Do) 4. A force of 6N is required to increase the speed of a box from a rate of 2 m/s to 4 m/s within 6 seconds along a level surface.
What change would most likely require additional force to
produce the same results?

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.

where is the circuit diagram ?

unbalanced force
