The mercury manometer of fig. p2.57 indicates a differential reading of 0.30 m when the pressure in pipe a is 30-mm hg vacuum. determine the pressure in pipe
b.

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.
