Question
Chapter 3, Problem 139RQ
Interpretation Introduction
Interpretation:
The formula of superconductor has to be determined.
Concept Introduction:
The conversion factor is a fraction obtained from a relationship between the units. It is written as a ratio and can be inverted to give two conversion factors for every relationship.
The appropriate conversion factor for any equality is selected in such a way, so that it results in the proper unit cancellation.
