Space is best associated with which of the following? a. biosphere b. exosphere c. geosphere d. cryosphere e. atmosphere f. hydrosphere only one answer.

Option (B)

Explanation:

Exosphere is the region of the upper atmosphere of earth and here the amount of air molecules is significantly less, forming a thin layer with certain amount of hydrogen and helium. This layer extends upto a height of about 10000 km and here the particles moves very rapidly, thereby the temperature at this region is relatively high. From the exosphere region the space starts and it is the region in which the artificial satellites are orbiting around the earth.

Thus the correct answer is option (B).

the correct option is option a

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.
