Электромагнитная индукция, генератор Правильно дополни предложения, описывающие процесс выработки электроэнергии на гидрозлектростанции, необходимыми понятиями. 1 строительства ГЭС по сравнению сдругими влектростанциями занимзет У источник энергии считается дешевле. 3В стране ГЭС строятся за давления на морское дно через строительство дамб и плотин 4. БЫстрое вращение лапастей генератора происходит за счет V энергии
Давление на дно сосуда зависит от высоты столба и рода жидкости в сосуде. Так как жидкость у нас одна - вода, а высота разная воспользуемся формулои гидростатического давления. (Вычисляем)

Давление больше в левом сосуде на Δp = 2,8 (кПа)
Объяснение:
Давление на дно сосуда зависит от высоты столба и рода жидкости в сосуде. Так как жидкость у нас одна - вода, а высота разная воспользуемся формулои гидростатического давления. (Вычисляем)
Дано:
h1=38 см = 0,38 м
h2=9 см = 0,09 м
g=9.8Н/кг
p(в) = 1000 кг/м^3
Наити:
Δp - ?
p₁ = p(в)gh₁ p₁ = 1000 кг/м^3 * 9.8Н/кг * 0,38 м = 3724 (Па)
p₂ = p(в)gh₂ p₂ = 1000 кг/м^3 * 9.8Н/кг * 0,09 м = 882 (Па)
Δp = p₁ - p₂ = 3724 (Па) - 882 (Па) = 2842 (Па) ≈ 2,8 (кПа)
ответ: Давление больше в левом сосуде на Δp = 2,8 (кПа)
