A sailboat moving in the direction shown is tacking to windward against a north wind. The log registers a hull speed of 5.1 knots. A "telltale" (light string tied to the rigging) indicates that the direction of the apparent wind is 32° from the centerline of the boat. What is the true wind velocity vw? Answer: Vw= i Uw 43° 32° knots 5.1 knots

Nuclear Physics

Nuclear physics is the branch of physics and nuclear science that analyses atomic nuclei and their structure, along with the study of other types of nuclear matter. Nuclear physics must not be misunderstood with atomic physics, which studies the atomic element as a whole, inclusive of the electrons.
