Question

Определите выталкивающую силу, действующую на затонувший корабль объёмом 10,5м3 в пресной воде. Ответ дать в kH

Answer 1

Дано:
V=10.5 м³
ρ=1030 кг/м³
Fa=ρ(ж)gVт.=10.5*10*1030=108.15 кН

Answer 2

Calculating Buoyant Force on a Sunken Ship

To calculate the buoyant force acting on a sunken ship, we can use the formula:

Buoyant force (B) = weight of the water displaced

The weight of the water displaced can be calculated using the formula:

Weight of water displaced = density of water × volume of water displaced

Given: - Volume of the sunken ship (V) = 10.5 m^3 - Density of freshwater = 1000 kg/m^3 (approximately)

Calculation

Using the given volume of the sunken ship and the density of freshwater, we can calculate the buoyant force.

Buoyant force (B) = weight of the water displaced

Weight of water displaced = density of water × volume of water displaced

Substituting the values: Weight of water displaced = 1000 kg/m^3 × 10.5 m^3

Weight of water displaced = 10500 kg

So, the buoyant force acting on the sunken ship in freshwater is approximately 10500 kH.
