## anonymous one year ago If 20 waves of water pass you in 10.0 s and the waves are 2.0 m long, how fast are they moving? A. 1.0 m/s B. 2.0 m/s C. 4.0 m/s D. 8.0 m/s ***Thank you!! :D

I think that we have to compute this quantity: $\Large v = \frac{{20 \times 2}}{{10}} = ...$ since 1 wave passes at eac 0.5 seconds

4. Michele_Laino
