3) Gold is a very dense metal with a density of 19.3 g/cm3, what is the volume of a 0.255 kg gold sample? (Answer = 13.2 cm³). Equality 1: g = kg Equality 2: g = cm3 0.255 kg x

Carry the following conversions: a. 2.5x10 -10 g in to kg if kg = 10 3 g; b. The label on a small soda bottle lists the volume of the drink as 6.75x10 2ml, how many fluid ounces are in the bottle if 1 ounce (oz) = 29.5725 ml

Problem 1. The standard kilogram used to be a platinum–iridium cylinder 39.0 39.0 mm in diameter. What is the density of the material? in height and

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).
