(b) The platinum nugget would have mass and would be worth 2.29 million dollars. Reflect: The platinum nugget is worth more because a nugget of the same size has more mass, since platinum’s den- sity is greater, and because it is worth more per ounce. The value if platinum is larger than the value if gold by 13.6. Set Up: The volume of a cube with side length L is The volume of a cylinder of radius r and length L is Solve: (a) The volume of the metal left after the hole is drilled is the volume of the solid cube minus the volume of the cylindrical hole: The cube with the hole has mass and density (b) The solid cube has volume and mass The original weight of the cube was 13.7. Set Up: Solve: (a) so and (b) Reflect: If the volume is decreased while the mass is kept the same, then the density increases. 13.8. Set Up: where and are the masses of the two volumes of liquid before they are mixed. where and are the volumes of the two liquids before they are mixed.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
