5. A diesel fuel tank has been filled with gasoline and runs until it quits. Which of the following should be done?

Which of the following is the best description of the power stroke? The ignition of the air fuel mixture increases pressure in the cylinder, which applies force to the face of the piston, driving it down. As the piston travels upward, it pushes the products of combustion out of the open exhaust valve. The crankshaft drives the piston down as the flywheel absorbs the energy created by the ignition of air fuel mixture. An air-fuel mixture is drawn into the combustion chamber as the piston moves toward the bottom of the cylinder.

The best type of propellant for engines that need to turn and and off multiple times during a mission is     cryogenic (hydrogen) propellant     solid (aluminum) propellant     traditional (kerosene) propellant     hypergolic (hydrazene) propellant

An advantage of using natural gas, rather than oil, as a fuel is that natural gas is?
