Physics

Which of these is dimensionless?


ANSWER

Energy$$/$$work


SOLUTION
i) $$\displaystyle \frac {Force}{acceleration}=\frac {kg.m.s^{-2}}{m.s^{-2}}=Kg$$

ii) $$\displaystyle \frac {Velocity}{acceleration}=\frac {m.s^{-1}}{m.s^{-2}}=s$$

iii) $$\displaystyle \frac {Volume}{Area}=\frac {m^3}{m^2}=m$$

iv) $$\displaystyle \frac {Energy}{Work}=\frac {J}{J}=1$$
