The spring of the pressure gauge shown in the figure below has a force constant of 1 100 N/m, and the piston has a diameter of 1.40 cm. As the gauge is lowered into water in a lake, what change in depth causes the piston to move in by 0.500 cm? m Vacuum k Submit Answer 4. [-/1 Points] DETAILS SERPSE10 14.2.OP.005. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The small piston of a hydraulic lift (see figure below) has a cross-sectional area of 2.70 cm, and its large piston has a cross-sectional area of 202 cm. What downward force of magnitude F, must be applied to the small piston for the lift to raise a load whose weight is F. = 15.2 kN? F N Need Help? Read It Watch It
