Problem
1.4 Explain this statement clearly : "To call a dimensional quantity 'large' or 'small' is meaningless without specifying a standard for comparison". In view of this, reframe the following statements wherever necessary : (a) atoms are very small objects (b) a jet plane moves with great speed (c) the mass of Jupiter is very large (d) the air inside this room contains a large number of molecules (e) a proton is much more massive than an electron (f) the speed of sound is much smaller than the speed of light.Intuitive explanation
Dimensional quantities like length, speed, and mass have no absolute meaning—they're only meaningful when compared to a reference standard or scale. Without context, saying something is "large" or "small" is just opinion. The key is to identify what natural or conventional scale makes sense for comparison, then reframe each statement to explicitly reference that benchmark.
