Description

The image is a diagram showing the energy efficiency of a rocket. The diagram is divided into several sections, each representing a different aspect of the rocket's energy efficiency. The sections include the energy efficiency of the rocket's engine, the energy efficiency of the rocket's fuel, and the energy efficiency of the rocket's structure. There are also several labels on the diagram, providing information about the different aspects of the rocket's energy efficiency. The labels include "energy efficiency of engine," "energy efficiency of fuel," and "energy efficiency of structure." The diagram is a useful tool for understanding the energy efficiency of a rocket and how it can be improved.
