A piece of ice with a volume of 0.1m3 floats on the water surface (ρ ice = 0.9 × 103kg). How to calculate the buoyancy of the ice A piece of ice with a volume of 0.1m3 floats on the water surface (ρ ice = 0.9 × 103kg) to calculate the buoyancy of the ice. Why is the buoyancy of ice calculated by its density rather than the density of water

A piece of ice with a volume of 0.1m3 floats on the water surface (ρ ice = 0.9 × 103kg). How to calculate the buoyancy of the ice A piece of ice with a volume of 0.1m3 floats on the water surface (ρ ice = 0.9 × 103kg) to calculate the buoyancy of the ice. Why is the buoyancy of ice calculated by its density rather than the density of water

The ratio of its density to the density of water is its fraction in water

What is the volume of water after a 1m3 piece of ice is melted into water? (known ρ ice = 0.9 × 103kg / m3)

Mass = density * volume. Under the condition of constant mass, density and volume are inversely proportional
Water volume = ice volume * ice density / water density = 1 * 0.9 * 10 ^ 3 / 1.0 * 10 ^ 3 = 0.9m ^ 3

It is known that the density of ice is 0.9 × 103kg / m3. When a certain volume of ice melts into water, its volume will be ()
A. Increase 110b. Decrease 110C. Increase 19d. Decrease 19

∵ ρ = MV, ∵ M = ρ V, ∵ mass is the property of the object, the mass of the ice water is unchanged, ∵ ρ water V water = ρ ice V ice, V water = ρ ice V ice ρ water = 0.9 × 103kg / m3 × V ice 1 × 103kg / m3 = 910v ice, volume change: V ice-v water = V ice-910v ice = 110V ice

The wood block with mass of 1.5kg floats on the water surface, and 2 / 5 of its volume is exposed to the water surface. What is the buoyancy of the wood block? What is the density of the wood block? What is the process

Floating: F floating = g = mg = 1.5kgx10n / kg = 15N
There is also f floating = ρ water GV drainage
V row = f floating / ρ water, g = 15N / (10 & # 179; kg / M & # 179; × 10N / kg) = 1.5 × 10 ^ (- 3) M & # 179;
(1-2 / 5) v = V row
V matter = (5 / 3) V row = 2.5 × 10 ^ (- 3) M & # 179;
ρ matter = m / V matter = 1.5kg/2.5 × 10 ^ (- 3) M & # 179; = 0.6x10 & # 179; kg / M & # 179;
