You have 9 stones that are identical in appearance. one of these stones weighs just a bit more than the other 8. these other 8 stones are exactly the same in weight. using a balance scale only twice, how can you determine exactly which stone is the heavier?

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
