You now conduct a series of experiments with electro-migration at the same 2 temperatures (T₁ = 25 C and T₂ = 60 C). The current density at T₁ was 2 mA/m² and the current density at T₂ was 1 mA/m². This time, the activation energy is changed to 0.7 eV. As a result of this series of experiments, the MTTF₁ = 1300 hours, and MTTF₂ = 400 hours. Determine both empirical constants (A(w) and N) in Blacks Equation
