• # question_answer Dimensions of bubble constant are: A)  $[ML{{T}^{-1}}]$             B)  $[ML{{T}^{4}}]$C)  $[{{M}^{o}}{{L}^{o}}{{T}^{-2}}]$             D)  $[{{T}^{-1}}]$

The formula for bubble constant is $H=\frac{\text{velocity}}{\text{distance}}$ Therefore the dimensions of the Hubble constant $=\frac{distance\text{ }of\text{ }velocity}{dimension\text{ }of\text{ }distance}$
