નીચેનામાંથી કયા સંબંધની મદદથી પરિમાણનું પૃથ્થકરણ કરી શકાય છે?
A
$N_0e^{-\lambda t}$
B
$A \, sin (At + kx)$
C
$\frac{1}{2}\,m{v^2}\,\, + \,\,\frac{1}{2}\,\,I{\omega ^2}$
D
આપેલ એક પણ નહિ
Solution
None of these can be derived using dimensional analysis because dimensional analysis can only tell the dimensional quantities that constitute the formula and not the constant values. In above relations, there are constant values, $N _0, A$ and $\frac{1}{2}$ which can't be determined by dimensional analysis.
