The piston diameter is 0.95 cm. What is the mass (in kg) of the weights required? Question 3 (15 points) The reading on a mercury manometer at 20 °C (open to the atmosphere at one end) is 28.71 inches. The local gravity is 32.186 f/s. The local atmospheric pressure is 101.29 kPa. The density of mercury at 20 °C is 13.495 g/cm3. What is the absolute pressure being measured, both in kPa and in psia? Question 4 (10 points) The gravity on Mars can be measured with a spring, which suspends a mass of 0.40 kg. On earth, where the local acceleration of gravity is 9.81 m/s, the spring extends 1.55 cm. When the instrument package is landed on Mars, the spring is extended only 0.59 cm. What is the acceleration of gravity on Mars?
