Mathematical equation for tsunamis

Ask an Expert Topic Forum: Grades 6-8: Life, Earth, and Social Sciences

Mathematical equation for tsunamis Mathematical equation for tsunamis Help! My daughter is doing a science fair project on tsunamis: study the effect of water depth on wave velocity. All the steps and analyzing our data are done. However, at the very end of the Science Buddies project, it wants an additional calculated result to show similar shaped curves on a graph compared to the results we experimented with. The equation is V=sqrt(gd) V=velocity in meters/second (m/s) g=acceleration of… Read more
