How is the moon's orbit around the earth related to an apple falling from a tree? Question 3 options: The earth's gravity keeps the moon in orbit, and also pulls objects toward the ground The earth, the moon, and an apple are all spherical, so they all have gravity The moon's gravity hold apples on tree branches, while the earth's gravity pulls apples toward the ground The moon's gravity affects bodies of water; the earth's gravity affects solid objects

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.

explanation:

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.

the correct answer is d

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
