Archimedes established his principle while investigating a suspected fraud in the construction of a crown. The crown was made from an alloy of gold and silver instead of pure gold. Assume that the volume of the alloy was the combined volumes of components (the density of gold is 19.3g⁄(cm^3 ), the density of silver is 10.5g⁄(cm^3 )). If the crown had a weight of 9.81 N in air and 9.10 N in pure water, what percentage of gold (by weight) was it?
1. A non-uniform is 4.5m long and weighs 640N. It is balance when a 270N weight is hung 0.800m from the light end of the bar and the bar is pivoted at its center.

Suppose four 30-g ice cubes are added to a glass containing 200 cm3 of orange juice at 20,0°C.You may assume that the orange juice has a density and specific heat capacity the same as water namely: Density = 1,0 g∙cm–3 and specific heat = 4,184 J/gK The heat of fusion (of water) is 333 J/g.Your task is twofold. You must determine:a) Whether or not all the ice will melt; andb) If your finding is that some ice will be left in the juice, you must calculate what mass of ice will be present the moment when thermal equilibrium is reached.
