D.1-Supplied constants and data

Use supplied constants such as g, c, e, u, particle masses, Avogadro constant, gas constant, Boltzmann constant, gravitational constant, permittivity of free space, Planck constant and Stefan-Boltzmann constant.

Use d.1-supplied constants and data to connect the rule to the data and decision in the question.

This matters because d.1-supplied constants and data determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply d.1-supplied constants and data to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: D.1-Supplied constants and data is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
