The spring of the pressure gauge shown in Figure P9.20 has a force constant of 1250 N/m, and the piston has a radius of 1.20 cm. As the gauge is lowered into the water, what change in depth causes the piston to move in by 0.750 cm?

The combustion reaction of gasoline vapor in an automobile cylinderaccelerates the piston at 2024 cm/s^2. The piston has a mass of500.0 g and a diameter of 5.50 cm. Calculate the pressure inPascals exerted on the piston by the expanding gases in thecylinder.(Useful hints: 1. Remember from Newton's Law in Physics that force= mass time acceleration 2. Area - pi x (radius)^2 and 3. Pressure= Force/Area; Pascals = N/m^2
In a hydraulic garage lift, the small piston has a radius of 4.0 cm and the large piston has a radius of 20 cm. What force must be applied on the small piston in order to lift a car weighing 20,000 N on the large piston? Assume the pistons each have negligible weight.
