ATSC 113 Sail Module A Exam Questions with Correct Answers Group velocity - Answer-speed at which one group of waves travels across the water Phase velocity - Answer-Speed of each wave in the group Wind generated waves - Answer-1. Capillary waves 2. Gravity waves Capillary waves (ripples) - Answer-- Small winds displace small amounts of water on the surface, creating very short wavelength waves - capillarity acts as the restoring force - only a few cm in length Gravity waves ...

Fetch, wind velocity, duration -The factors that affect wave formation include: Fetch, duration, distance Fetch & wind velocity Fetch, wind velocity, distance Fetch, wind velocity, duration Duration & wind velocity (b) & (c) -Drag is: (a) & (b) (b) & (c) (b) Friction when wind moves across the surface of water (a) Friction when wind moves across the surface of air (c) Force that acts against the relative motion of one fluid with respect to another fluid

1 ATSC SAILING EXAM | QUESTIONS & ANSWERS (VERIFIED) | LATEST UPDATE | GRADED A+ What are the three factors that affect wave formation? Correct Answer: wind velocity, fetch, and duration what is wind velocity for wave formation Correct Answer: the speed of the wind what is fetch for wave formation Correct Answer: the distance over the water that the wind can blow uninterrupted (which can be huge distances out at sea) what is duration for wave formation Correct Answer: the amount ...
