In a scientific experiment, the one variable that is purposely changed to test a hypothesis is called the manipulated variable. select the best answer from the choices provided t f

True

Explanation:

In a scientific experiment, the one variable that is intentionally changed by the researcher to know the affect of such change over other variable is called as independent or manipulated variable. It is changed to perform the experiment to test the hypothesis.

The other variable which is not changed intentionally is the dependent variable.

On the basis of the above explanation, the given statement is true.

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.
