Physics 204 Experiment 10 continued 3. (3 points) What is the force sensor measuring? The force sensor is measuring the apparent weight of the hanging mass. 4. (3 points) Do your free body diagrams explain why the buoyant force is the difference between the force readings before and after submersion? Explain. Yes because the Boyant force is the difference between the force due to tension and the force of gravity, before submersion it is zero and

(3 points) The calculated value of the density of water is 832kg/m^3. The standard value for the density of water is 1000 kg/m 3 . (3 points) The percent difference between your calculated value of the density of water and the standard value is 16.8%. Questions 1. (3 points) Does the data support Archimedes’ principle? Yes, it does. 2. (3 points) What are some of the sources of error in the experiment? Misreading the data can cause the results to be slightly skewed, from the sensor graph as well as the flask.

    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.
