Given: ruler 11.56 g, small washer 1.85 g each, large washer 24.30g each
Use the data in Data Tables 4 and 5 to experimentally determine the mass of your ruler. Use one of your 2 trials with 1 small washer at 0 cm, one of your 2 trials with 2 small washers at 0 cm, and one of your 2 trials with 3 small washers at 0 cm to find three experimental values for the mass of the ruler.
How do you experimentalls determine the mass?
Compare the 3 experimental masses of your ruler to the measured mass of your ruler (Data Table 1) by calculating the percent error for each experimental value. Which trial provided the best data for determining the mass of the ruler?
Please help, I am not sure how to calculate this. Thanks!
Please help, everytime I try to input the data only one point shows on the graph. Please graph unsing centripetal force, Fc, versus V E2 from Activity 1. Include a line of best fit and record the equation of the line. Thank you!
