PRE-LAB Questions:
1) You use a force sensor to measure the weight of an object 10 times, and get the following values: 2.8, 2.6, 2.9, 3.1, 2.4, 2.9, 3.2, 2.5, 2.7, 3.0, where all ten values are in units of N. What is the mean weight of the object, as well as the measurement uncertainty of the weight?
2) You measure the mass of the object from question 1 to be m = 300.8 g with an uncertainty of ± 0.1 g. Using this value of mass and the mean weight from question 1, calculate the acceleration of gravity g, as well as the uncertainty in your calculated value of g. EXP 2 - PRELAB
3) If the accepted value of g is 9.8 m/s2 , what is the percent error of you calculated value of g?

You measure the length of a board with a ruler that is older and has a worn-down end. If you align the end of the board with the end of the ruler, what type of uncertainty does the end of the ruler contribute to the measurement?

2 Experiment: In the experiment conducted, the mass of the counter weight M was chosen to be 50.0 +/- 0.1 g The mass of the rubber stopper was measured to be 12.0 +/- 0.1 g The stopper was spun at five different values of the radius (measured with a meter stick). For each value of r, the time to complete 10 full revolutions was measured with stopwatch. The following data was collected: 40.0 60.0 80.0 100.0 (cm) 1) 120.0 10.74...

SPSS Homework 1 Instructions: Review and One-Way ANOVAs (40 points) Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember that we divide the p value in half when reporting one-tailed tests with 1 – 2 groups.

Need help With Analysis questions.
Ballistic Pendulum Lab In this lab, you will explore
conservation of Energy and Momentum in an inelastic collision
between a projectile and a cardboard box suspended from a string.
In particular, you will see that the transfer of linear momentum is
easily accounted for in an inelastic collision, but the transfer of
kinetic energy is not easy to measure directly. This is because
Kinetic Energy in collisions transfers to vibrational, acoustic,
and potential energy. Once...
