The two solid cubes have the same pressure on the horizontal plane, and the relationship between their density is The two solid cubes have the same pressure on the horizontal plane, and the relationship between their density is P1 > P2 (the letter of density will not be printed, instead of P). If the pressure of the two cubes on the horizontal ground is F1 and F2 respectively, then F1 is the same_________ F2 (greater than, less than, equal to) Why?

Let the lengths of two cubes be L1 and L2 respectively, then: (p1xl1 & sup3;) / L1 & sup2; = (p1xl2 & sup3;) / L2 & sup2;
So p1l1 = p2l2, so L1

A. B when two square solid metal blocks are placed on the horizontal ground, their side length ratio is 1:3, and the pressure ratio to the ground is 2:3, the density ratio of the two metals is ()
A. 4：9B. 9：4C. 1：2D. 2：1

According to P = FS = GS = MGS = ρ sghs = ρ GH, papB = ρ Agha, ρ aghb = ρ aha, ρ BHb = ρ a × 1, ρ B × 3 = 23, then ρ a, ρ B = 21

When the density of 1.5 × 10 cubic kg / M? Is used to build a boat, the volume of the boat is 20 cubic cm, resulting in a maximum drainage volume of 100 cubic cm
What is the maximum buoyancy of the boat?
When the density of 1.5 × 10 cubic rubber mud is used in shipbuilding, the volume of rubber mud is 20 cubic cm, resulting in a maximum drainage volume of 100 cubic cm.

F floating = ρ water GV drainage = 1.0 * 10 ^ 3kg / m ^ 3 * 10N / kg * 10 ^ - 4cm ^ 3 = 1n
