Examine the data and % error values in Data Table 2 where the mass of the pendulum bob increased but the angular displacement and length of the simple pendulum remained constant. Describe whether or not your data shows that the period of the pendulum depends on the mass of the pendulum bob, to within a reasonable percent error.
Please graph, my software isn't working -
Data Table 4 of Period, T vs √L . (Note: variables are identified for graphing as y vs x.) On the graph insert a best fit line or curve and display the equation on the graph.

- You are working during the summer at a company that builds theme parks. The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. Two parallel, horizontal rails extend from left to right, with one rail behind the other. A cylindrical rod rests on top of and perpendicular to the rails at their left ends. The distance between the rails is d and the length of the rails is L. The magnetic field vector B points vertically down, perpendicular to the rails. Within the rod, the current I flows out of the page, from the rail in the back toward the rail in the front. The rod is of length d = 1.00 m and mass m = 0.700 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 20.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude B = 2.30 T.
