Question

How big should the ice floe a = 0.3 m thick be to hold the weight of a 500 kg polar bear on the water? The ice density is dk = 917 kg / m3 and the water density is dw = 1027 kg / m3 .

Answer 1

Answer:

Hello mate..

Explanation:

The buoyancing force due to water = Weight of iceberg

V₁ρ₁g = mg = V₂ρ₂g

(V₁ × 1024) = (V₂ × 917)

V₁ = 0.89V₂

Iceberg visible = V₂ - V₁

= V₂ - 0.89V₂

= 0.11V₂

Fraction of iceberg visible = 0.11V₂/V₂ = 0.11

% Fraction of iceberg visible = 11 %
