Final answer:
Without the formulae for classical and relativistic calculations, we cannot calculate the exact percentage differences for z = 0.1, z = 0.5, and z = 1. Normally, we'd use differentials in these approximations.
Step-by-step explanation:
The percentage difference between the classical and relativistic results can be found using the given information that there is an 11% deviation at z = 0.2. To approximate the percentage difference at other values of z, we would need the specific formulae for both classical and relativistic calculations. However, without these formulae or additional context, we cannot provide the exact percentage differences for z = 0.1, z = 0.5, and z = 1. We would typically use differentials to approximate changes in a function for small values of the independent variables, implying some knowledge of the relationship between z and the change in question.
