Вопрос школьника по предмету Физика
Мраморная плита размером 2x1x0,5м оказывает на почву давление 13500 Па. Определить размеры основания плиты, если её масса 2,7 тонны.
Можно решение с дано и системой Си(если нужно)
Ответ учителя по предмету Физика
m=2700 кг
p= 13500 Па
Решение:
p=F/S
F = P = g×m
S основания = g×m / p= 9,8 × 2700 / 13500=1,96 м в квадрате
то есть площадь основания плиты 2 метра умножить на 1 метр, высота плиты 0,5 метра.
