what is  the fastest means of water transport?

It depends on whether you mean a boat or a personal watercraft.  I believe vessels that use the hydrofoil system are considered the world's fastest water craft.  These sites should help you.

No.  Sharks (and Dolphins which are actually faster than most sharks) are perfectly adapted for travel in water making them the fastest and deadliest (for fish, anyway) creatures in the sea.\n\nHumans, even with wet suits and flippers, will never approach the speed (or agility) of practically any fish or sea mammal except maybe a sea horse, unless they are strapped to some self propelled machine.  \n\nShark and Dolphin bodies are streamlined to slice through water and practically all the muscles in their huge bodies are devoted just for swimming (except maybe their jaws).  We just aren't streamlined enough and our muscles aren't designed to be powerful enough to push our awkward bodies through water.

If a molecule of the water is moving at 2m/s through the hose, it is because of the nozzle, not despite it. That molecule travels through the nozzle at 2m/s.

I'm not quite sure what you mean: distance between hole and surface.  Surface of what?\n\nHere is the scoop though: Holes that are closer to the bottom of the container, and therefore farther from the surface of the water, do yield a faster rate of flow.  As the hole moves closer to the surface of the water, the rate slows down.  \n\nThis is of course due to pressure of a fluid.  The deeper you are, the more pressure there is; therefore, the water is pushed out at a faster rate when the hole is farthest from teh surface.

water is essentially a better option.

An ion engine will get you there the fastest. You get the biggest delta-vee per kg of exhaust. \n\nProblem is, in general you only get one encounter with a specific planet once each solar orbit, and you can only get a kick so large each time. I suppose you can hypothesize a super convenient planetary alignment that could shave off some time, but you might spend a long time waiting for that particular configuration.  A lot of really smart people spent a lot of time developing the computational tools to come up with the VEEGA and VVEJGA options.  I doubt the population here is going to come up with anything a lot better.\n\nYou can read more about the DS1 ion propulsion experimental system here:\nhttp://nmp.nasa.gov/ds1/tech/ionpropfaq.html\n\nThe first science mission using ion propulsion is the Pluto bound New Horizons.  Thanks to this tech, it will reach pluto in 10 short years and reaches Jupiter for a gravity assist in only 1 year.\n\nhttp://pluto.jhuapl.edu/mission/mission_timeline.html

Opera is the fastest. Firefox is a lot of hype:\nhttp://mywebpages.comcast.net/SupportCD/FirefoxMyths.html

The cheapest way is Economy parcel Post...but it will travel by boat and can take as long as 3 months sometimes. The fastest, most inexpensive way is by Airmail Letter Post. You can ship any package under 4 pounds.

The water starts from one end and reaches the other end in 30 minutes\n\nThe distance traveled is 1700 meter. Time taken 30 minutes = 1800 second.\n\nThe velocity is distance traveled per second. Therefore, it is 1700 /1800 m/s =0.94m/s

Sound travels faster through water because the particles in water are already touching each other (in gases the particles are all spread out). [the other answers have dealt with this in more detail]\n\nHelium is less dense than air becuase helium molecules weigh less than regular air molecules (a molecule of helium is two helium atoms, so its atomic weight is 2x 2 = 4. Air is mostly nitrogen, with molecular weight 2x 14 = 28).\n\nHowever, the molecules in helium are almost exactly as close together as the molcules in air. In fact, in any gas, one mole of molecules takes up the same amount of space - 24 litres at standard temperature and atmospheric pressure.\n\nSo, sound can travel faster through helium because the particles are the same distance apart as air, but they are lighter so it is easier to get them moving.
