Ответ:

Чтобы рассчитать значение высоты подъема воды в трубке, необходимо воспользоваться равенством: Fт / S = mч * g / S = P (давление) = ρв * g * h, откуда выразим: h = mч / (S * ρв).

Значения переменных: mч — масса человека (mч = 75 кг); S — площадь контакта мешка и платформы (S = 1000 см2 = 0,1 м2); ρв — плотность воды в кожаном мешке (ρв = 1000 кг/м3).

Вычисление: h = mч / (S * ρв) = 75 / (0,1 * 1000) = 0,75 м.

Ответ: Вода в трубке сможет подняться на высоту 0,75 м.
