The time dependence of a physical quantity p is given by $ p = p_0 \exp(-αt^2) $, where α is a constant and t is the time. The constant α

Question

Accepted Answer

has dimensions T⁻². The argument of an exponential function must be dimensionless. Since the argument here is αt², the dimensions of α must cancel out the dimensions of t² (T²). Therefore, α has dimensions T⁻².
