Question

is my answer and process correct in the pic?

 

what is the answer to this?

  1. Consider the percentage difference between the and for the first two parts of the laboratory when known forces are balanced. A difference of 0.5% or less is excellent, a difference of 1.0% or less is good, and a difference of 2% or less is acceptable. Based on these criteria, describe your results for the first two parts of the laboratory and defend your statement.
