How do the changes inside the diver affect its position in the surrounding fluid?
Changes inside the diver, such as changes in buoyancy or density, can affect the diver's position in the surrounding fluid by causing the diver to either sink or float. For example, if the diver becomes less dense than the fluid, they will float to the surface. Similarly, if the diver becomes denser than the fluid, they will sink to the bottom.
How does pascal's principle help explain the behavior of the cartesians diver?
Pascal's principle states that when pressure is applied to a confined fluid, it is transmitted equally in all directions. In the Cartesian diver toy, squeezing the bottle increases the pressure inside, causing the diver to sink as the higher pressure compresses the air in the diver. Releasing the pressure allows the air to expand, making the diver float back to the surface.
How much pressure is exerted on a diver 10 m underwater?
The pressure exerted on a diver 10 m underwater is approximately 2 atmospheres or 1.8 times the atmospheric pressure at the surface. This means the pressure is effectively doubled at this depth.
What is causes the bends?
The bends, or decompression sickness, is caused by the formation of nitrogen bubbles in the bloodstream and tissues when a diver ascends too quickly from a deep dive. These bubbles can lead to a variety of symptoms, including joint pain, fatigue, and in severe cases, paralysis or death. Proper decompression stops and ascent rates can help prevent the bends.
What is the air resistance of a sky diver?
The air resistance experienced by a skydiver is significant as it opposes the downward motion, slowing the diver's fall. The magnitude of air resistance depends on factors such as the diver's speed, body position, and surface area exposed to the air. Skydivers often use specialized equipment like parachutes to control their descent by manipulating air resistance.
When a scuba diver dives into water why are the gas bubbles they release always spherical?
The gas bubbles exhaled by a SCUBA diver are always spherical for two reasons: the gas molecules are pushing outward from the bubble in all directions with the same amount of force. In addition, the water outside the gas bubble is squeezing the bubble inward in all directions with the same amount of force.
Why do the air bubbles of a diver head toward the surface?
Becuase air is less dense than water so it raises above it
Why it is dangerous for scuba diver to more up rapidly into the water surface?
A scuba diver should not ascend rapidly, because the nitrogen in their bloodstream will lose pressure and create bubbles in the bloodstream. This will cause decompression sickness, which can be fatal.
Why is it important for a deep sea diver to resurface at a gradual rate?
because bubbles of nitrogen that are abosrbed into the blood at high pressures but are normally insoluble start being released from the blood as the diver rises. If this happens to quickly bubbles in the blood form and the diver gets the bends
The stunt diver used an oxygen tank until he reached the surface?
The stunt diver
What do they call it when a scuba diver comes to surface to quick?
they get the bends
What is the reason for DCS?
If the diver surfaces too quickly, however, potentially dangerous nitrogen bubbles can form in the tissues and cause DCS. These bubbles can compress nerves, obstruct arteries, veins,
How do the changes inside the diver affect its position in the surrounding fluid?
Changes inside the diver, such as changes in buoyancy or density, can affect the diver's position in the surrounding fluid by causing the diver to either sink or float. For example, if the diver becomes less dense than the fluid, they will float to the surface. Similarly, if the diver becomes denser than the fluid, they will sink to the bottom.
Why do scuba divers form air bubbles in their blood stream?
When diving, scuba divers breathe gas under pressure. The greater pressure causes the nitrogen in the breathing gas to dissolve in their bodily tissues (the body metabolises the oxygen). When the diver ascends from depth, the pressure is reduced, and so the gas comes out of the tissues and into the bloodstream, where the diver expels it through his lungs. Normally these bubbles are very small (sometimes called "micro" bubbles or "silent" bubbles) and present no risk to the diver. Normal off-gassing in this was is not harmful, but if a diver stays too deep for too long, the rapid release of gas can form larger bubbles which can cause decompression sickness. In minor cases this can cause discomfort and localised swelling, which can normally be resolved with oxygen. Severe cases can lead to permanent tissue damage, paralysis and even death. This is why divers are trained to understand no-decompression limits and to utilise tables or dive computers to keep them safely within margins.
Did you ever in your life see a diver kiss his wife as the bubbles bounced about above the water?
Shiley Ellis flip side to NAME GAME single EVER SEE A DIVER KISS HIS WIFE (WHILE THE BUBBLES BOUNCE ABOUT ABOVE THE WATER) was written by Shirley Ellis (whose real name was Shirley Elliston) and Lincoln Chase. It was recorded sometime in 1963-65. It appears on the albums "The Complete Congress Recordings," Connoisseur Collection CD 30340, 2001; and "The Very Best of Shirley Ellis," Taragon CD 1005.
What are the two types of diver flags?
There are two types of diver down flags - the diver down flag and the alpha flag. The red diver down flag is used when divers are in the water to alert boats to the possibility of divers near the surface, and the blue alpha flag is flown by a boat whenever the mobility of the vessel is restricted.
