Can you please explain? Thank you

3. The velocity, u (m/s), of air flowing across a flat surface is measured at several distances y (m) away from the surface. (Think about a fan blowing air over a table and measuring the air velocity at several heights above the table.) Use Newton's viscosity law du T = Pdy and the second order centered first finite difference method to determine the shear stress, T (N/m2), at distances y = 0.006, 0.012, and 0.018 m. Assume a constant value for the dynamic viscosity u = 1.8 x 10 Ns/m. How do you think your answers would change if you use higher order finite differences? y (m) 0.000 0.00200 0.00600 0.0120 0.0180 0.0240 u (m/s) 0.000 0.287 0.899 1.915 3.048 4.299 Please show your work for one distance. You do not have to show your work for the remaining calculations
