A sky diver is falling through a Fluid with a measurable viscosity. The fluid is AIR. Pushing air molecules out of the way, and having them rub along the body of the skydiver's clothing causes friction (heat). This resulting friction on a human sized body results in a terminal velocity of approximately 124 MPH (200 KPH).

What friction causes a sky divers to change as she falls?
As a skydiver falls, air resistance causes friction against her body, gradually slowing her down. This friction increases as her speed decreases, ultimately leading to a terminal velocity where the forces of gravity and air resistance balance, resulting in a constant falling speed. This friction also helps stabilize the skydiver's position during free fall.
Do sky divers go up when a parachute opens?
Sky divers do not go up, but they do undergo deceleration due to the increased drag incurred by the parachute being suddenly opened. Since skydivers, when being filmed by a cameraman, release their parachute first, there is a relative acceleration between the cameraman and the skydiver, creating the illusion that the skydiver is travelling up.
How dangerous is it for divers when sonar is used in the water?
When sonar is used in the water, it can be dangerous for divers because the sound waves produced by sonar can disorient or harm marine life, including divers. The intensity and proximity of the sonar signal can impact the safety of divers, potentially causing injury or discomfort. Divers should be cautious and aware of sonar use in their diving areas to minimize risks.
Why are Cartesian Diver called Cartesian divers?
Cartesian divers are named after French philosopher and scientist René Descartes. The divers demonstrate principles of buoyancy and pressure in fluid mechanics that Descartes contributed to understanding. The diver's movement within the fluid is a visual representation of these principles.
How does sonar affect divers underwater?
Sonar can disrupt the navigation and communication of divers underwater, potentially causing disorientation and confusion. The sound waves from sonar can also disturb marine life and affect their behavior.
What friction causes a sky divers to change as she falls?
As a skydiver falls, air resistance causes friction against her body, gradually slowing her down. This friction increases as her speed decreases, ultimately leading to a terminal velocity where the forces of gravity and air resistance balance, resulting in a constant falling speed. This friction also helps stabilize the skydiver's position during free fall.
What causes pulmonary oxygen toxicity?
Pulmonary oxygen toxicity is caused by divers exposing themselves to elevated partial pressures of oxygen for long periods of time, and is primarily a concern for technical divers who decompress on oxygen. Pulmonary oxygen toxicity causes a burning sensation in the trachea, coughing, shortness of breath, and eventually lung failure.
What is the collective noun for divers?
A bubble of divers
What are three factors that made pearl diving so dangerous in the early 1900s?
Free divers risk the danger of drowning while underwater, especially in areas requiring divers to descend to extreme depths. All pearl divers risk encountering dangers under the water, including sharks and other sea life. Many Australian pearl divers perished during storms that claimed the pearling boats while the divers were still on the bottom. Beyond environmental hazards, pearl divers also have to cope with the "bends," a condition caused when rapid decompression from quick surface ascent causes nitrogen bubbles to form in the bloodstream.
When was Shadow Divers created?
Shadow Divers was created in 2004.
What are skin divers?
Skin divers are people who dive into the ocean without using special equipment, unlike Scuba divers.
How do you use dive in a sentence?
To use it in that form, you could use it as a command. For instance, Dive into the water. To use it in another way, you would have to change the verb tense to "dove" or "diving" or something else like that.
How many pages does Shadow Divers have?
