Average crew complement (depending on mission / deployment status) can be between 90 - 160, depending on the boat class. Standard for most boats is between 90-120 for normal operations.
A. The cost of a submarine cable depends on its length, how many fibres it contains and the number of channels it is intended to carry. To give you an idea, a single transatlantic cable would cost around $500m ( £307,443,000). We can carry out feasibility studies and costings for any systems you may be considering.
The first underwater warship was developed by Leonardo da Vinci. da Vinci kept his plans secret because he didn't want to make war any more terrifying than it already was. In 1578 William Borne began drawing plans for a submarine. His submarine was never built. Borne's submarine worked by using extra tanks which could be filled so the submarine would submerge. The tanks would be emptied for the submarine to surface. In 1620 Cornelis Drebbel, a Dutch inventor, built a leather covered rowboat with oars. The oars came out through watertight seals. Twelve people could ride in the submarine. Drebbel was an engineer who worked for the British navy. Drebbel was the first to discuss the problem of air replenishment while the submarine submerged. Drebbel's submarine could only go down about fifteen feet. It could stay underwater for a couple of hours.
Carpenters, Builders, Engineers, Surveyors, Architects, Mathematicians, Astronomers and in general many other people from all walks of life use angles to carry out their jobs.

The submarine
David Bushnell's "Turtle" submersible was designed to carry one person; the operator.
No, for the same reason that the crew of a nuclear submarine doesn't wear parachutes.
Ohio class submarines carry 24 Trident missiles.
A submarine have a crew ranging from about 70 to 120 crewmembers. However, it is so small and compact that it can't normaly carry passengers, if that's what you're asking.
If you mean how many people it can carry then it can carry three people.

Depending on the size of the submarine and whether it is peace or wartime.U-Boat. 27 -> 57Non Nuclear ~ 40Nuclear ~ 80 (more in wartime)
study submarine procedures and sleep
Depends on the type of submarine...
The submarine is manned by the crew, and crew members are called submariners.
A submarine is kept at, or close to, surface air pressure.
Actually the submarine will not kill any one, but the rockets and torpedo launched from the submarine kill the people.
