The drawing shows a hydraulic chamber with a spring (spring constant = 1770 N/m) attached to the input piston and a rockof mass 47.0 kg resting on the output plunger. The piston and plunger are nearly at the same height, and each has anegligible mass. By how much is the spring compressed from its unstrained position?Area = 15 cm²Area = 65 cm²

A spring is attached to the bottom of an empty swimming pool, with the axis of the spring oriented vertically. An 25.0-kg hollow block of wood (p = 840 kg/m³) is fixed to the top of the spring and compresses it. Then the pool is filled with water, completely covering the block. The spring is now observed to be stretched twice as much as it had been compressed. Determine the percentage of the block's total volume that is hollow. Ignore any air in the hollow space.

You put a marble on a balance and find it has a mass of 1.2 grams. It is an irregular shape, so you need to do displacement to find its volume. You put it in a graduated cylinder with a starting volume of 30.0 mL of water. After you add the marble, the water rises to 31.5 mL. What is the density? Group of answer choices 0.038 g/mL 1.3 g/mL 0.80 g/mL 1.8 g/mL
A rectangular bar made of nickel (B=7.8×1010 Pa) has dimension of 50.0 cm by 30.0 cm by 15.0 cm when it is on the surface of the earth where the pressure is 1.013×105 Pa. The bar is then taken to the bottom of the sea where all of its dimension decreases by 0.200%.What is the pressure exerted on the rectangular bar at the bottom of the sea?

4. A light spring of constant k = 90.0 N/m is attached vertically to a table. A balloon (with empty mass 2.50 g) is filled with a mixture of helium (density = 0.179 kg/m³) and air (density = 1.29 kg/m³) to a volume of 4.00 m³ and is then connected to the spring, causing the spring to stretch. If the spring stretches by 1.0 cm, find the required density of the gas mixture, and find how much helium and air you need to produce that mixture.
