Aroller coaster car picks speed as it rolls down a slope. as it starts down the slope, its speed is 4m/s. 3 seconds later, at the bottom of the slope, its speed is 22m/s. find its acceleration.

acceleration = 18/3 = 6 m/s per second.

-lavira: )

eukarya because is is like alche and b is bacteria and d is animals

explanation:

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
