Which of the following objects would require the use of a large-scale model? (2 points) An atom A car engine A frog's heart The Mississippi River

1. An atom is an object that needs a large-scale model. A large-scale model must be bigger than the object itself.

2. The correct answer among the choices provided is option C. It is a theory that light travels at 300,000 kilometers per second.

Explanation:

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
