Q5. Report the slope and uncertainty in the slope of the linearfit on your graph, include the correct units. Q6. Use your reportedslope from the graph to calculate the spring constant k, andinclude the correct units. Show all work. Q7. Using propagation ofuncertainties, it can be shown that the uncertainty in the springconstant k may be calculated using Using your graph for theuncertainty in the slope, along with your answer to Q6, calculatethe uncertainty in the spring constant. Show all work.
m=2.14 +- 0.46, b=-0.0074+-0.0097, r=0.937. The graph wouldn'tupload.
