Camera because it would be helpful to photograph the dunes at different times and compare the differences resulting from wind.
C Camera. I think this because you can make timelapses with cameras which makes it easy to see.

Answer:
<u>20 m/s</u>
Explanation:
<u>Given</u>
- u(A) = 20 m/s
- u(B) = 30 m/s
- acceleration equal in magnitude but opposite in direction
<u>Solving</u>
- Velocity of A at Q = 30 m/s
- From, P to Q, <u>Δv(A) = 30 - 20 = +10 m/s</u>
- Therefore, velocity of B at Q will be decreased by 10 as it is equal in magnitude but opposite in direction to A
- Δv(B) = v(B at Q) - u(B at P)
- -10 m/s = v(B at Q) - 30 m/s
- v(B at Q) = 30 - 10 = <u>20 m/s</u>
