Question

Зайки помогите пожалуйста ( С какой силой шарик объемом 25 см3 выталкивается из глицерина? Ускорение свободного падения считать равным 10 Н/кг, плотность глицерина 1250 кг/м3. Ответ указать в килопаскалях без округления, единицы измерения указывать не нужно

Answer 1

Ответ:

$F_{A} = 1250*10*0.000025 = 0.3125 N = 0.0003125 kN$

kN - килоньютоны

N - ньютоны

Calculation of the Force Required to Displace the Ball from Glycerin

To calculate the force required to displace a ball with a volume of 25 cm³ from glycerin, we need to consider the buoyant force acting on the ball. The buoyant force is equal to the weight of the fluid displaced by the ball.

The formula to calculate the buoyant force is:

Buoyant force = (density of fluid) × (volume of fluid displaced) × (acceleration due to gravity)

Given: - Volume of the ball = 25 cm³ - Acceleration due to gravity = 10 N/kg - Density of glycerin = 1250 kg/m³

First, we need to convert the volume of the ball from cm³ to m³: - 1 cm³ = 1 × 10⁻⁶ m³ - Volume of the ball = 25 × 10⁻⁶ m³

Now, we can calculate the buoyant force using the formula mentioned above:

Buoyant force = (1250 kg/m³) × (25 × 10⁻⁶ m³) × (10 N/kg)

Calculating the above expression will give us the force required to displace the ball from glycerin.

Please note that the search results did not provide any relevant information for this specific calculation. However, the calculation is based on the principles of buoyancy and the given parameters.
