A) \[Z\propto r\]
B) \[Z\propto \frac{1}{r}\]
C) \[Z\propto \frac{1}{{{r}^{2}}}\]
D) \[Z\propto {{r}^{3/2}}\]
Correct Answer: A
Solution :
Bubbles law is the statement in physical cosmology that the red-shift (Z) in light coming from different galaxies is proportional to their distance (r). i.e., \[Z\propto r\] It is considered the first observational basis for the expanding space and today serves as one of the most often cited pieces of evidence in support of the Big bang.You need to login to perform this action.
