Hide the solution
"A" has the greatest surface area for burning. The more fuel that is burnt every second the greater the thrust produced by the engine. "B" has less surface area for burning than "A". "C" burns from the bottom up and is very slow compared to "A" and "B".
Hide the solution
Jet engines need air in order to burn their fuel. There is no air in space.
Jet engines are similar to rocket engines in that they both mix oxygen and fuel before igniting the mixture. The gas produced quickly expands with the heat that is also produced and escapes from the nozzle with great force.
Jet engines are different to rocket engines in that rocket engines must carry their own oxygen.
