13.66. Set Up: Apply Newton’s second law to the beaker, liquid and block as a combined object and also to the block as a single object. Take upward. Solve: Forces on the combined object: D and E read mass rather than weight, so write the equation as is the reading in kg of scale D ; a similar statement applies to Forces on A : (b) D reads the mass of A : 8.20 kg. E reads the total mass of B and C : 2.80 kg. 13.67. Set Up: The density of gold is and the density of aluminum is Solve: Find the volume of the ingot: The mass of the ingot is The total mass is the mass of gold, plus the mass of aluminum, The total volume is the volume of gold, plus the volume of aluminum, Reflect: If the ingot had the same weight in air (45.0 N) and was pure gold, its volume would be and the balance would read 42.7 N when the ingot was submerged. 13.68. Set Up: The pressure at the surface of the earth is The height of fluid in the barometer is related to air pressure p by Solve: (a) (b) 13.69.

### What students are saying

• 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.
