if a cubic tank holds 1000 kg of water. What are the dimensions of the tank in meters? Explain your reasoning.

A cubic box is completely filled with 1,728g of water. What is the length of one side of the box , in meters? Explain your reasoning

what is the density of aluminum if 3.50 cm3 has a mass of 9.45 g? Please report answer to the correct amount of significant figures.

In the diagram below there is a thick-walled cylindrical tube. Its height is H = 5.0 m, its inner radius is R1 = 1.0 m, its outer radius is R2 = 3.0 m and its mass is M = 10.0 kg. The volume density is proportional to the square of the height h measured from the top of the cylinder: p x h?. R2 a) Proof that the proportionality constant k (p = kh?) is k = , ms 100m b) Determine the position of the center of mass of this object. c) Determine I, the moment of inertia of the cylindrical tube around the axle going through the center of the top (as shown on diagram). You can use lying =mr? (the rotational inertia of a ring of radius r and mass m rotating around an axis parallel to it, through its center).
