Based on the study of buoyant force and the hydrometer, i finally know what is hydrometer, what is the use of hydrometer and how the buoyant force effect the boat and ships. Just now i realized the existence of safety line on boats and how heavier people affect it. Thank you to Pn. Wahida for giving me such a chance to improve myself and experience of using the application on daily life. Thank you.
