What part of a diver's body might be hurt during a deep dive and why is this so?
A diver's ears can be hurt during a deep dive due to changes in pressure. As a diver descends, the pressure increases, causing the eardrum to push inward. Failure to equalize the pressure by clearing the ears can lead to barotrauma, causing pain, discomfort, and potentially injury.
What is a Cartesian Diver most known for?
The Cartesian Diver is actually a scientific experiment. It helps divers determine what amount of air is needed for descent and ascent so that neither is done too quickly which can cause death.
What is a holy diver?
"Holy Diver" refers to Satan's descent to hell, or his "dive." The lyrics deal with Revelations 12:9 where Satan was cast to earth. The tiger is symbolic of the wild beast that comes out of the sea, as mentioned in Revelations 13:1.
If no friction acts on a diver during a dive?
More friction acts on a diver when they dive because of the increased density of the water.
What is the diver gravitational potential energy just before the dive?
The diver's gravitational potential energy just before the dive is at its maximum, as the diver is at the highest point in the dive and has the most gravitational potential energy. This potential energy will be converted to kinetic energy as the diver falls during the dive.
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.
How do you prevent the pain caused by airplane cabin pressure changes?
You have to equalize the pressure in your ears regularly. Some people do so by yawning or swallowing, which can be effective, but if that doesn't work, then you should blow as hard as you can through your nose while holding it shut. It's a scuba diver trick and works pretty well if everything else doesn't.
What divers should do for their safety?

Should divers do for their own safety?

What is a Olympic diver?
A diver that competes in the Olympics or a diver that has competed in past Olympics.
What should divers do for theirs own safety?
remain close to the diver down flag
Why do scuba divers exhale slowly as they ascend to surface?
The First Stage ..( the bit on the tank) of a diving regulator senses the pressure exerted on the regulator ( and also on the body) to see how much it is being squeezed, it then compensates for the pressure by filling your lungs with more air than they could hold on the surface BUT because the lungs are being "squashed" the air fills your lungs like normal. The only potential problem comes when you ascend..because you have too much air in your lungs as it starts to expand, it could overinflate your lungs to the point they literally blow up!
