A 1500 kg car speeds up from zero to 3.0 ms. it has kinetic energy of 6750 J at top spreed. True or False?

True

KE = 1/2 mv^2

m = 1500 kg

v = 3 m/s

KE = 1/2 (1500 kg)(3 m/s)^2

KE = (750 kg)(9 m^2/s^2)

KE = 6,750 J

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.  

answer: y=0 if that is what u r looking for
