A diver is located 63 m below the surface of the ocean (the density of seawater is 1025 kg/m3). To raise a treasure chest that she discovered, the diver inflates a plastic, spherical buoy with her compressed air tanks. The radius of the buoy is inflated to 0.41 m. If the treasure has a mass of 215 kg, what is the acceleration of the buoy and the treasure chest when they are tethered together and released? The chest is 22...
A scuba diver at a depth of 34.0 m below the surface of the sea off the shores of Panama City, where the temperature is 5.0°C, releases an air bubble with volume 15.0 cm3. The bubble rises to the surface where the temperature is 19.0°C. What is the volume of the bubble immediately before it breaks the surface? The specific gravity for seawater is 1.025. Submit Answer Tries 0/5
An air bubble released by a deep-water diver, 120 m below the surface of a lake, has a volume of 1.65 cm3. The surface of the lake is at sea level, and the density of the lake water can be approximated as that of pure water. As the bubble rises to the surface, the temperature of the water and the number of air molecules in the bubble can each be approximated as constant. Find the volume (in cm) of the...
When the U.S. submarine Squalus became disabled at a depth of 56.5 m, a cylindrical chamber was lowered from a ship to rescue the crew. The chamber had a radius of 2.18 m and a height of 3.88 m, was open at the bottom, and held two rescuers. It slid along a guide cable that a diver had attached to a hatch on the submarine. Once it reached the hatch and clamped to the hull, the crew could escape into...
When the U.S. submarine Squalus became disabled at a depth of 66.3 m, a cylindrical chamber was lowered from a ship to rescue the crew. The chamber had a radius of 1.43 m and a height of 2.05 m, was open at the bottom, and held two rescuers. It slid along a guide cable that a diver had attached to a hatch on the submarine. Once it reached the hatch and clamped to the hull, the crew could escape into...
A scuba diver is 45 m below the surface of a lake, where the temperature is 5°C. He releases an air bubble with a volume of 10 cm3. The bubble rises to the surface, where the temperature is 25°C. Assume that the air in the bubble is always in thermal equilibrium with the surrounding water, and assume that there is no exchange of molecules between the bubble and the surrounding water. What is the volume of the bubble right before...
A scuba diver is 45 m below the surface of a lake, where the temperature is 5 degree C. He releases an air bubble with a volume of 18 cm^3. The bubble rises to the surface, where the temperature is 25 degree C. Assume that the air in the bubble is always in thermal equilibrium with the surrounding water, and assume that there is no exchange of molecules between the bubble and the surrounding water. What is the volume of...
9. A diver weighing 600 N drops from a board h meters above the surface of the water. If the speed of the diver when she is h/4 meters above the surface is 5.0 m/s, find h. 10. A block with mass 5.0 kg is attached to a horizontal spring with spring constant 300.0 N/m. If the block is initially pulled out a distance x cm and then released, and its velocity when it first reaches the equilibrium point is...
A lost shipping container is found resting on the ocean floor and completely submerged. The container is 6.4 m long, 2.4 m wide, and 2.5 m high. Salvage experts attach a spherical balloon to the top of the container and inflate it with air pumped down from the surface. When the balloon's radius is 1.7 m, the shipping container just begins to rise towards the surface. What is the mass of the container? Ignore the mass of the balloon and...
Many people have imagined that if they were to float the top of a flexible snorkel tube out of the water, they would be able to breathe through it while walking underwater. However, they generally do not consider just how much water pressure opposes the expansion of the chest and the inflation of the lungs. Suppose you can barely breathe while lying on the floor with a 370 N weight on your chest. How far below the surface of the...
