$E=E_0 e^{-t / t_0}$

Vedclass · Answer

(D) For an equation to be dimensionally correct,the exponent of an exponential function must be dimensionless. In the expression $E=E_0 e^{-t / t_0}$,the term $-t / t_0$ is the ratio of two times,which is dimensionless. Since $E$ and $E_0$ both represent energy,they have the same dimensional formula $[M L^2 T^{-2}]$. Therefore,the equation $E=E_0 e^{-t / t_0}$ is dimensionally consistent because the exponential factor $e^{-t / t_0}$ is a dimensionless constant. Other options are dimensionally incorrect because their exponents are not dimensionless or the dimensions on both sides do not match.

If $E$ and $E_0$ represent the energies,and $t$ and $t_0$ represent the times,which of the following relations is dimensionally correct?
