Because helium will not mix with hydrogen and oxygen.
A large rocket holds a lot of fuel, a small rocket holds less.
Helium is a gas; no ores or minerals. Helium exist in natural methane gas and also is released in very small amounts from many rocks containing uranium.
AMMONIA
A rocket motor (rocket engine) does not need air from the atmosphere. It carries the oxidant (source of oxygen) as well as the fuel.
A balloon does not move like a rocket. A helium filled balloon will float upward because the density of helium is less than that of air, so it is effectively "lighter". A rocket is propelled in any direction using a booster engine that burns fuel.
liquid fuel
Rocket Fuel Inc. (FUEL) had its IPO in 2013.
Rocket fuel.
Modern model rocket fuel is a solid fuel.
The symbol for Rocket Fuel Inc. in NASDAQ is: FUEL.
At the very bottom is the nozzle, after that is the fuel. Depending on how big the rocket is and how much fuel it needs determines the size of the chamber
First, they release Helium(he).They take more fuel than objects.It starts to fire.The elevators helps to go proper.If there any crack the gasket blasts.
As of July 2014, the market cap for Rocket Fuel Inc. (FUEL) is $854,306,979.24.
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
Rocket fuel is either liquid or solid. Other kinds are being developed.
How much fuel will be needed in a rocket will depend on the size of the rocket and where it is going. A rocket that will be traveling into space burns a lot of fuel and will need enough to keep it in orbit for teh desired time.
