Please analyze the absolute error and relative error of the following three physical formulas: (1) Please give the expressions of absolute error and relative error; (2) If the relative error of each independent variable is ±3%, please find the total relative error; (3) If the relative error of each independent variable is ±5%, please find the total relative error. The physical formulas are as follows: 1 2 3 Formula F = G Mm r² T= 27, m k D=1.88d (1+1)
