At which position (A or B} is the uid velocity greater? 0 Neither Q) A O B O Not enough information is given to establish which of the other answers is correct. Question 7 1 pts In the hydraulic system depicted below, the area of the face of the small piston on the left is 4.00 cm2. The area of the face of piston on the right is 600 cm2. The maximum force that the operator can apply to the piston on the left is his weight which is 730 newtons. With the aid of such a hydraulic system, the maximum load that the operator can lift is approximately how many times his weight? sPPuED Fa R LE Q 240 O 12.5 C) 114 000 150 0 None of the provided answers is correct.
