the combustion reactions that occur in the engines of a rocket lead to pressure gradients that cause the gaseous products to rush out of the rocket into the atmosphere. what is created by this process?

The correct answer is thrust.

Explanation:

The force that moves the rocket up in the air, and via space is termed as the thrust. It is produced by the rocket's propulsion system through the use of third law of motion given by Newton. The thrust in the rocket is a result of the pressures functioning in the nozzle and the combustion chamber.

The passing of the hot exhaust takes place via a nozzle that increases the flow. The thrust generated by the rocket relies upon the rate of mass flow via the engine, the pressure of the nozzle exit, and the exit velocity of the exhaust.

The answer is thrust. The action is the fuel mass being pushed outside of the rocket booster at a fast rate while the reaction is the rocket pushing forward. The force creates Thrust.
