Question

sharita and antoine are scientists who are calculating the amount of energy transferred into disko bay by warm water every hour. they use the same data and the same mathematical model, but their answers end up being off from each other by just a tiny amount. what is the most likely source for this apparent error? their measurements are incorrect. their mathematical model (equation) is based on bad assumptions or data. they did not collect enough samples. only one of them used the correct rules for significant figures.

Explanation:

Since they use the same data and model, incorrect measurements, bad - assumptions/data in the model, and insufficient samples are not likely causes. Differences in significant - figure rules application can lead to small discrepancies in results.

Answer:

Only one of them used the correct rules for significant figures.
