My answer is "Watt per square meter".
They begin to adapt into their new location. They then end up having adaptations to help them survive.
Answer:
Explanation:
a) Power consumption is 4100 J/min / 60 s/min = 68.3 W(atts)
work done raised the potential energy
b) 75(9.8)(1000) / (3(3600)) = 68.055555... 68.1 W
c) efficiency is 68.1 / 68.3 = 0.99593... or nearly 100%
Not a very likely scenario.

The position vector r:

The velocity vector v:

The acceleration vector a:
