A golden-colored cube is handed to you. The person wants you to buy it for $100, saying that is a gold nugget. You pull out your old geology text and look up gold in the mineral table and read that its density is 19.3 g/cm3. You measure the cube and find that it is 3cm on each side, and weighs 40 g. What is its density? Is it gold? Should you buy it?
A golden-colored cube is handed to you. The person wants you to buy it for $100, saying that is a gold nugget. You pull out your old geology text and look up gold in the mineral table, and read that its density is 19.3 g/cm3. You measure the cube and find that it is 2 cm on each side, and weighs 40 g. What is its density? Is it gold?
Should you buy it? Draw also a figure or free body diagram that support the problem, and the discovery after solving it.
When equal masses of two substances are mixed, the resultant density is 2.5 g/cm^3. When equal volumes are mixed, the resultant density is 4.5 g/cm^3. What are the densities of the two substances?

The planet has an average radius of 6370 km, so that the oceans form a very thin layer overall! The deepest known part of the ocean is the Mariana Trench, north of Papua New Guinea and east of the Phillipines, with a depth of almost 11000 m. If Mount Everest was placed at the bottom of the Mariana Trench, it would still be submerged by more than 2000 m!
