A scientist is calculating the density of an ore sample. The scien- tist measures that the ore sample weighs 22.4 N in air. When the sample is suspended by a thin light cord and totally immersed in water, the tension in the cord is 14.2 N. What is the density of the ore sample that the scientist calculates. You can assume that any buoyant force from air is negligible.

In the hydraulic system shown in the figure (see below) the piston on the left has a diameter of 5.2 cm and a mass of 2.0kg. The piston on the right has a diameter of 15 cm and a mass of 3.6 kg. If the density of the fluid is 700 kg/m^3, what is the height difference h between the two pistons?
You are trying to lift a car to change a tire using a hydraulic jack. You apply a force of 57 N to the input piston who's diameter is d1. As a result, the output piston, which has a diameter d2, applies a force to the car. The ratio d2/d1 has a value of 7.2. Ignore the height difference between the input piston and output piston and determine the force that the output piston applies to the car.

A liquid-filled tube called a manometer can be used to measure the pressure inside a container by comparing it to the atmospheric pressure and measuring the height of the liquid. Such a device (filled with water) is shown in the figure, measuring the pressure inside a balloon filled with an unknown gas. The water level on the side of the manometer which is open to the air is 12.2 cm higher than on the side connected to the balloon. a. Find the gauge pressure in the balloon, in units of Pa. Recall the density of water is 1000 kg/m3. b. Find the absolute pressure in the balloon, in units of Pa.
