Description

The image is a diagram showing the energy efficiency of a jet engine. The diagram is divided into two sections, one showing the energy efficiency of the jet engine and the other showing the energy efficiency of a rocket engine. The jet engine is shown to be more energy efficient than the rocket engine. The diagram is labeled with various terms, such as "energy efficiency," "energy output," "energy input," and "energy conversion." The energy efficiency of the jet engine is shown to be 90%, while the energy efficiency of the rocket engine is shown to be 10%. The diagram also includes a graph showing the energy efficiency of the jet engine over time.
