Because a hovercraft rides on a cushion of air, there is less contact between a hovercraft and water, so there's less friction to slow it down as compared to a regular watercraft.
A hovercraft travels on a bubble of air and has very little contact with the water or land it travels over - a boat has to push the water out of the way, so needs lots of power to do this. When hovering, a leisure hovercraft weighs as much as a seagull standing on one leg! Recreational Hovercraft travel at speeds of up to 40 miles per hour, and racing models reach speeds of 75 mph. Hovercraft are very lightweight.
Ir probably goes down faster if its heavier. If the ball was as light as a balloon, would it go faster? OF course not. So, a heavy ball would go MUCH faster down a hill.
Through temperature, concentration, surface area, and the use of catalists. Temperature - most reaction go faster with a higher temperature (not always the case) So you raise or lower the temperature to control the speed. Concentration - this can be calculated. The higher the concentration the faster the outcome and the more product you get. Catalists will always make it faster. More catalist, fater reaction. Surface Area-The more surface area, the faster the reaction. for example, if you break up an antacid tablet (alka seltzer) it will dissolve faster than a whole one because it has more surface area
Yes you can, but you would have to hold your breath and make sure that you exhale quickly, because underwater there is no oxygen. You will hear it but the projectile will not go as fast because the water will slow it down. You would not be able to fire another shot unless you supply your own oxygen or surface and inhale.
You lose more when you go faster: when you go faster the amount of friction increases and thus the amount of energy you lose increases.
It has a greater surface area than the single piece of iron
a surface with an air intake
Modern submarines are designed to go much faster submerged. This design also limits their surface speed capability. WW1 and WW2 submarines were not considered true submersibles by today's standards. They were essentially surface vessels that had the capability of limited submerged operations. As such, their design and propulsion made them faster on the surface and much slower underwater. Modern submarines are true submersibles in that their only limitation is that of their crews.
The pressure is less at the surface as opposed to being underwater.
the smoother the surface the faster you go the bumper the surface the slower you go. smooth surface less effort to go farther and vice - versa
Dolphins can't breathe underwater because they are mammals. They go to the surface to breathe and then hold their breath while underwater
you have to dive underwater by sootopolis city and you have to go in the little cave underwater where youll find the sud and then you surface there.
No but they go up to the surface every 30 minutes.
No, they have to surface to breathe. They can go a long time between breaths though.
No.
Who said things go faster as they get nearer to a black hole ? Oh yes ... an objectfalling under the influence of gravitation is accelerated. OK. But no. Things do, butlight is not an object, and it doesn't go faster than 300,000 km/sec .
USA. nuclear powered submarines can go faster than 25 knots (nautical miles per hour) underwater.
You have to search Underwater on Route 128 to find a secret cavern with a submarine in it, then go to the surface.
