A scientist kept 1,000 gram samples of radioactive carbon, radium, and plutonium in three different containers. The table below shows the half-lives of the three radioactive materials. Radioactive Material Half-life (in years)
carbon 5,700
radium 1,620
plutonium 6,563

Based on the table, which of these conclusions is most likely correct?

A. After 20,000 years, approximately 250 grams of carbon and radium will be left in the containers.

B. After 6,000 years, approximately 500 grams of carbon and plutonium will be left in the containers.

C. After 6,000 years, approximately 250 grams of carbon and radium will be left in the containers.

D. After 20,000 years, approximately 500 grams of carbon and plutonium will be left in the containers.

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:

fabric is silk wool ext. paper isnt

explanation:

u cant make fabric out of paper cause paper comes from wood while fabric comes from animals

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:
