- Please help, everytime I try to input the data only one point shows on the graph. Graph of centripetal force, Fc, versus V E2 from Activity 1. Include a line of best fit and record the equation of the line.arrow_forwardBased on your graph, explain how centripetal force is affected when the hanging mass changes. Does your graph verify the relationship in the equation r = x^i + y^j = r cos ωt I + r sin ωt^j?arrow_forwardDid your experiment results in Data Table 3 verify, to within a reasonable experimental error, the condition of equilibrium of Equation 6: Στanti-clockwise = Στclockwise? Support your response with experimental data. My data shows that they are not equal to each other. So what does this mean? Thanks!arrow_forward

Theillumination is so bright that that a faint inverted image, due to reflection off the front of the lens, is observedat 6.0 cm on the incident side of the lens. The lens is then turned around. Then it is observed that the faint,inverted image is now 10 cm on the incident side of the lens.What is the index of refraction of the lens?arrow_forward2. In class, we discussed several different flow scenarios for which we can make enough assumptions to simplify the Navier-Stokes equations enough to solve them and obtain an exact solution.
