D
Explanation: this was easy for me
heterogeneous, because it does not have a uniform texture
hope That helps
According to the formula you have given us to work with . . .
1). The airplane's acceleration is
(80 m/s north - zero) / (20 sec) = 4 m/sec^2 north
2). For the cyclist:
(V-final - zero) / 20sec = 0.5 m/s^2 south
Multiply each side by 20s : V-final = 0.5 m/s^2 south x (20sec) =
10 m/s south
Would all have the same ratio of elements.
Don't trust atoms, they make up everything.
How about chemical workers... are they unionized?
