Why does a scuba diver need more weight in the ocean than in fresh water?
A scuba diver needs more weight in the ocean than in fresh water because salt water is denser than fresh water, making it more buoyant. The additional weight helps the diver sink and maintain a neutral buoyancy underwater.
What do we have that the ocean doesn't?
We have weight and the ocean doesn't. But sort of in a way, if you take the water out of the water, you will find that that it does have weight!
What is a person who goes into water headfirst is called?
A person who goes into water headfirst is called a diver.
What are the answers to 14.10 punchline Algebra book b marcy math works?
A diver springs from the edge of the ocean with an initial upward velocity of 8 ft/s. How long will it take the diver to reach the water?
What do you call someone who goes into water headfirst?
a diver
At 10 feet the pressure is about 4.3 PSi It is unsafe for amateur divers to swim where the water pressure is more than 65 PS How deep can an amateur diver swim safely?
Assuming that by 'amateur diver' you mean a recreational diver without any professional qualificaitions, the recommended limit as determined by PADI (Professional Association of Diving Instructors) is 18m (60ft) for an Open Water diver, 30m (100ft) for Advanced Open Water and 40m (120ft) for a Divemaster. BSAC (British Sub Aqua club) sets the limits as 20m (67ft) for an Ocean Diver, 30m (100ft) for Sports Diver and 50m (165ft) for Master Diver. So in answer to your question, no, you couldn't 'swim where the water pressure is more than 65 ps' unless you were a technical diver or a BSAC qualified diver, as at 165ft the pressure is around 69ps.
What percentage of sodium chloride is in ocean water?
Ocean water is approximately 3.5% sodium chloride by weight.
Why does the diver speed decrease just after entering the water?
The drag force exerted by the water on the diver rapidly decelerates the diver's speed after entering the water. This force opposes the motion of the diver and causes a quick decrease in speed. Additionally, the change in medium from air to water also affects the diver's speed.
How do you use the word submerged in a sentence?
the water submerged all the way to his neck
The buoyancy force on a submarine submerged in the ocean equals?
the weight of the ocean water displaced by the submarine.
When a diver jumps off a diving board gravity pulls him or her to the water What is the reaction force to Earth's gravity?
Gravity always acts as a pair of forces, not as one single force. The strength of the forces depends on both masses, not just one of them. The forces of gravity attract the diver toward the earth and the earth toward the diver. The forces are equal in both directions. If the diver weighs 150 pounds on earth, then the earth weighs 150 pounds on the diver. The diver accelerates toward the center of the earth with an acceleration equal to (weight)/(diver's mass), and the earth accelerates toward the diver with an acceleration equal to (weight)/(earth's mass). Has that helped, or just confused the issue further ?
Two divers are diving in clear ocean water at a depth of 175 m One diver shows a white marker board to the other with writing on it What color will the marker board appear to be?
