kepler and newton studied the movement of planets. kepler studied the speed of the planets while newton studied the forces that kept the planets in place. which of these statements best explains why the two scientists proposed different theories about the planets?

they had different goals.
they studied different models.
they used different sets of data.
they misinterpreted their findings.

They had different goals.

Explanation:

Although they focused their studies on astronomy and the factors that compose it, we can see from reading the above question that Kepler and Newton had different purposes in their studies (Newton even used many of Kepler's notes to take as a basis for their theories). As we can see, Keple's goal is to understand how fast the planets moved and what factors resulted and influenced that speed. On the other hand, Newton's goal was to know how the planets would not get out of their places, even moving at high speeds.

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:

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
