Apiece of plastic (sample q), was heated at a constant rate. after 20 minutes of adding heat, the plastic melted. when an identical piece of plastic (sample r), was heated with twice as much heat per minute, the plastic melted in 10 minutes. how do the melting points of the two pieces of plastic compare?
a. the melting point of sample r is double that of sample q.
b. the melting points of sample q and sample r are the same.
c. the melting point of sample r is slightly higher than sample q's.
d. the melting point of sample q is higher than sample r's.

The correct answer is option B which is the melting points of sample Q and sample R are the same.

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:

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
