Question

Бетонная плита длиной 2 метра, шириной 1 метр и толщиной 10 см полностью погружена в воду. Вычислите архимедову силу. помогите пожалуйста

Answer 1

v=0.1*2*1=0.2кубических метра- это v плиты погруженной в воду, а Vтеа погруженного равен Vвытесненной жидкости, а дальше по формуле из учебника

Answer 2

Calculating Archimedes' Force

To calculate the Archimedes' force acting on the concrete slab submerged in water, we can use the formula:

F = ρ * g * V

Where: - F is the Archimedes' force, - ρ is the density of the fluid (in this case, water), - g is the acceleration due to gravity, and - V is the volume of the fluid displaced by the object.

Given: - Length of the concrete slab (l) = 2 meters, - Width of the concrete slab (w) = 1 meter, - Thickness of the concrete slab (t) = 10 cm = 0.1 meters.

We can calculate the volume of the concrete slab as follows: V = l * w * t

Substitute the values and calculate the volume.

Next, we need to find the density of water and the acceleration due to gravity.

The density of water is approximately 1000 kg/m^3 and the acceleration due to gravity is approximately 9.8 m/s^2.

Now, we can calculate the Archimedes' force using the formula mentioned above.

F = ρ * g * V

Substitute the values of ρ, g, and V to find the Archimedes' force acting on the concrete slab when it is fully submerged in water.

Let's calculate the Archimedes' force using the given information and the formula.
