A spring with spring constant k = 35 N/m is attached to the ceiling. A cylinder with mass m = 1 kgand diameter d = 5 cm is attached to its lower end. The cylinder is first held, such that the spring1is neither stretched nor compressed, then a tank of water is placed underneath with the surface ofthe water just touching the bottom of the cylinder. When released, the cylinder will oscillate a fewtimes but, damped by the water, quickly reaches an equilibrium position. When in equilibrium,what length of the cylinder is submerged?

The pressure at the bottom of the Marianne Trench in the Pacific Ocean is about 1.8 × 10^8 Pa. Find an expression for the decrease in volume, expressed as a fraction if we move a given mass of water from the surface to that depth.
A scuba diver makes a slow descent into the depths of the ocean. His vertical position with respect to a boat on the surface changes several times. He makes the first stop 8.0 m from the boat but has a problem with equalizing the pressure, so he ascends 2.0 m and then continues descending for another 12 m to the second stop. From there, he ascends 3.0 m and then descends for 17 m, ascends again for 8.0 m and descends again for 22 m, where he makes a stop, waiting for his buddy. Assuming the positive direction up to the surface, express his net vertical displacement vector in terms of the unit vector. What is his distance to the boat? Enter the exact answers. The scuba diver's net displacement is Number m Ĵ. The scuba diver's distance to the boat is Number m.
V A solid brass (bulk modulus 6.7 x 1010 N/m²) sphere is subjected to a pressure of 1.0 x 105 Pa due to the earth's atmosphere. On Venus the pressure due to the atmosphere is 9.0 x 106 Pa.

It has recently become possible to "weigh" DNA molecules by measuring the influence of their mass on a nano-oscillator. Figure shows a thin rectangular cantilever etched out of silicon (density 2300 kg/m³) with a small gold dot at the end. If pulled down and released, the end of the cantilever vibrates with simple harmonic motion, moving up and down like a diving board after a jump. When bathed with DNA molecules whose ends have been modified to bind with gold, one or more molecules may attach to the gold dot. The addition of their mass causes a very slight-but measurable-decrease in the oscillation frequency. A vibrating cantilever of mass M can be modeled as a block of mass M attached to a spring. (The factor of arises from the moment of inertia of a bar pivoted at one end.) Neither the mass nor the spring constant can be determined very accurately-perhaps to only two significant figures-but the oscillation frequency can be measured with very high precision simply by counting the…

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.
