Discussion: The density of the ball was measured to be 1.1289. It was determined as accurately as possible by following the above listed procedures and following them. The error for the entire experiment was also found as 0.0451. The experiment was found to be a success as the error of 0.0451 is less than 5% of the actual value of the density. Error: Mass error: This is the possible error taken into consideration for the mass, as the mass didn’t have enough values to be evaluated with standard deviation. This is a measurement error. It was estimated to the hundredth of a gram. Diameter measurement error: This is affected by the fact that the ball’s diameter varied with every measurement using the vernier callipers. There are different values for measurement. The ball wasn’t solid: The ball’s nature makes it possible for there to be variance in the diameter of the ball. Air Resistance when measuring mass: Air resistance affects the values of the mass of the ball being measured. Procedure Questions: 1. The object floats or sinks depending majorly on its density. If the objects density is greater than 1 i.e. (density of water), then it will sink. If its density is less than 1, it will float 2. The ball sank. The ball behave as it should have given my predicted density. The error in the density was small enough to be ignored. 3. The % error was less than 5%, hence the experiment was a success. Conclusion: The error in the density was negligible and the ball’s density was greater than 1.0, hence the ball sunk below the water surface. We calculate the volume and mass of the ball considering its errors and found its density.

### 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.
