Question

Кусок сплава из меди и цинка массой 5,16 кг весит в воде 45,6 H. Найдите выталкивающую силу

Answer 1

Ответ: 6Н

Объяснение:

F арх=P-P1=mg-P1, где Р1- вес тела в жидкости, Р- вес тела в воздухе

F арх= 5,16кг*10Н/кг - 45,6 Н= 51,6Н-45,6Н=6 Н

Answer 2

Calculation of Buoyant Force

To calculate the buoyant force acting on the copper-zinc alloy in water, we can use the following formula:

Buoyant force = Weight of the water displaced

Given: - Mass of the copper-zinc alloy (m) = 5.16 kg - Weight of the alloy in water (W) = 45.6 N

First, let's calculate the weight of the alloy in air using the formula: Weight in air = Mass × Acceleration due to gravity

Weight in air = 5.16 kg × 9.81 m/s²

Weight in air = 50.6796 N

Now, we can calculate the buoyant force using the weight of the water displaced: Buoyant force = Weight in air - Weight in water

Buoyant force = 50.6796 N - 45.6 N

Buoyant force = 5.0796 N

Therefore, the buoyant force acting on the copper-zinc alloy in water is 5.0796 N.
