Scuba

Boyle's Law, Charles's Law, and Archimedes principle are the main principles. Study those and that should get you started.

I would think so, because there are two of them mixed together. Air in a scuba tank or anywhere else should be heterogeneous. A scuba tank filled with either oxygen or nitrogen would be homogeneous.

In short, It depends!

The CD version is great because you can save the file and then you don't have to worry about taking it with you wherever you go in the world as its on you laptop/email or however you would store it. It is also very easy to search for specific things in the manuals as you can use keywords. However, you may be reluctant to take you laptop on a boat or near the water.

The book is also useful as you can take it with you on the boat/near the water with less worry than a laptop and it doesn't need a power source. The downside really is that you have to carry it around with you wherever you are teaching, although that's not as much of a problem any more as the PADI Instructor Manual from last year has been replaced, it's no longer a monster!

It basically comes down to you, whichever you think you would prefer to use on a regular basis. A computer, or a book.

Personally, I wish I had chosen the CD but that is because i had the old (huge) manual and struggled to get that, my dive gear and my clothes on a plane without paying a stack in excess baggage.

Regulator is what you breathe in

People generally fill cylinders by going to a dive shop or through your club. You can find diving clubs and diving shops in a number of directories or on-line. Some dive centres like the National Diving and Activity Centre also have filling stations. If you have a certified cylinder that is in date, you will find it easy to get a fill. If your cylinder is not in date it may be dangerous to fill. Most clubs have compressors and you will also find there are lots of divers like myself who have their own diving compressor who may be able to help you out.

In my opinion, I think they won't, as they are timid creatures. They only attack when threatened or when they smell blood. trust me, you wouldn't want to place your injured leg in the sea, as the shark will leap out of the water even it is 97cm away from the surface of the sea!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You are in the Caribbean Sea.

AnswerScuba Divers cannot rise from the water too fast because if they come up too fast they get that feeling like when you are on a roller coaster and you go over a hill really fast and they could die from that because the pressure is much greater

WRONG if a scuba diver comes up too fast their body fills with a deadly amount of nitrogen which then makes the blood boil, therefor can cause death.

CORRECT ANSWER:

A diver while under water breathes a higher percentage of Nitrogen than he does on the surface. As he come up this nitrogen expands (boyles law) and if you dont come up nice and slowly (which allows you to just breathe out the excess) it can form bubbles in the blood which cause Decompression Sickness (the bends). Imagine a bottle of soda if you shake it the gas expands in the solution. If you open the bottle slowly the gas escapes without any real problem, however if you open the bottle quickly the soda will bubble everywhere - this is the same basic principle.

I found an old reference book and converted to modern units. 53 'feet' is 16.16 metres. Every 10 metres pressure increases by one atmosphere, so 16.16 metres equals 1.616 'extra' atmospheres, or, total 2.616 atmospheres at 16.16 metres. So...on any given day, to find the total pressure at your '53 feet', multiply local ambient pressure (in whatever units you prefer) by 2.616 to determine total (absolute) pressure at that depth. Don't ever forget, all naturally occurring pressures are dynamic; all pressures at all depths will be significantly higher on "good" weather days, than on "bad".
[(53/33)+1] = 2.61

Yes, you can if you have a lobster license. You can get one easily. However, after a certain amount, you need a commercial license. If you can find a pond or lake with them, you can dive for them with a license.

your wetsuit will immediately fill with noxious flatulence gases thus causing you to ballon like macy's day parade float and you are then immediately projected to the surface where you the pressure equalizes and the gas immediately attempts to reenter your anus thus causing you to implode and the remnants immediately eaten by a massive flatulence eating shark.

You can convert shoe sizes to scuba flipper sizes by choosing fins that are full finned or encase the entire foot. These are sized exactly like shoes are sized. Open fins, or the type with the strap that goes around the back of your foot, are sized just one size larger than your normal shoe size.

Its not really scuba diving but its considered scuba diving. Also known as the hookah system. its when you have a gas powered motor pumping fresh air to the person or person's diving below, there can be up to four people diving off of one hookah system. the benefit of this system is that there is no decompression time and you can be underwater pretty much all day if someone fills the gas tank on the engine pumping air. but you are kinda tied down to something so i don't think its true scuba diving.

Yes. But only if you do not plan to dive later that day or even the following day depending on what time it is.

Yes. There is no law that prevents uncertified divers diving. However, most shops require some kind of training for liability reasons.

However, many organisations (including PADI), offer "discover scuba diving" courses (sometimes referred to as "resort courses" because they are often done on holiday), which take just a half a day, and allow you to dive under the supervision of an instructor to limited depths.

By going to your local PADI Dive Center and doing you Open Water SCUBA Diver course.

You will learn to set up, put on and use all the gear effectively and safely in as little as 3 days

Most people burn calories because of the body's attempt to maintain its temperature while scuba diving. Rescue divers burn additional calories while doing more strenuous movement underwater. You can burn a great deal of calories if you had to swim against a strong current or in a medium current for a long time. Estimates show that an average person burns 600-1000 calories per hour while diving.

The answers to the Padi advanced open water driver manual chapters are not provided online. The individual who is studying this will need to read through the manual and discover the answers in order to best prepare for the driving test.

If you don't the oxygen in the compressed air will come out of solution as the pressure reduces as you surface. If that happens, oxygen bubbles can get into the blood stream, causing a condition known as the bends. Depending on the severity of the bends (which takes into account MANY different conditions), it can range from pain in the joints, to death.
