Mary smith obtained a density of 2.226g/ml for a metal sample. Using a different method, Joseph Henry obtained a value of 2.335g/mL for the same metal sample. Which student’s value is more accurate? Use the definition of accuracy to explain your answer. the true value is 2.300g/ml.

Joseph Henry.

Explanation:

Hello,

In this case, we define the accuracy based on the degree of deviation a measure has regarding the the true or expected value. In this case, the lower the difference, the more accurate the procedure. In such a way, for the two students, we compute the difference between the expected value and the obtained value:

In such a way, since the difference is lower in Joseph's measure, we can say he is the most accurate.

Best regards.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
