Объяснение:

Дано:

F=8Н

g=10Н/кг

ρ=1030кг/м³

-----------------

V-?

F=ρgV

V=F/(ρg)=8/(1030*10)=7,8*10⁻⁴м³=0,00078м³


zinovicgrigorij: 7,8*10⁻⁴м³
zinovicgrigorij: 0.00078м³=780cм³=780000мм³ или еще нужны другие единицы
zinovicgrigorij: 7,8*10⁻⁴м³=0,00078м³=780cм³=780000мм³
zinovicgrigorij: F=ρgV

V=F/(ρg)=8/(1030*10)=7,8*10⁻⁴м³=0,00078м³
zinovicgrigorij: Нет, 8 разделить на 1030 и на 10
