The last film I watched was "fantastic critters, and where they inhabit". This movie is about what the main character wants to save, and save a fantastic world, among people. In this he is helped by two golduns, and a man. But that's what's stopping them. But in this they are hindered by the president/mayor of the city(countries.) Says these creatures are quite dangerous for World. That's why she starts to set up the creatures, which prevents her main character. I advise you to see it!
Известен объем тела V=0,1 м^3. Сила тяжести, действующая на тело Fт = 800 Н. Если сила Архимеда больше силы тяжести, то тело всплывет. Если сила Архимеда меньше силы тяжести, то тело утонет. Если силы тяжести и Архимеда равны, то тело будет "висеть" в воде. Найдем силу Архимеда, Fa = (ro)*g*V, где ro это плотность воды (табличная величина) ro = 1000 кг/м^3. g - это ускорение свободного падения, g=9,8 м/с^2. Fa = 1000 кг/м^3 * 9,8 м/с^2 *0,1 м^3 = 980 Н > 800 Н = Fт. Сила Архимеда больше силы тяжести, что значит, что тело всплывет на поверхность воды.
а разве не проще самим придумать?
