Make V the subject of the formula
A=c/2m(v²-u²)

v = √[(c/2mA)  + u²].

Step-by-step explanation:

A = c/2m(v² - u²)

Cross multiply

A * 2m(v² - u²) = c

v² - u² = c/2mA

v²   = (c/2mA)  + u²

v = √[(c/2mA)  + u²]

the answer is b

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
