Percent difference =
7.761
Is the measured value of
M
in close agreement with the value obtained from the slope? (A
difference of ±10% would be considered acceptable in this situation.)
If it is not, what are some of the sources of uncertainty in this lab that could have contributed to
this discrepancy? (Select all that apply.)
