Final answer:
The question addresses complex analysis involving an arc defined by a complex function, likely involving calculations such as normalization, velocity, displacement, or arc properties.
Step-by-step explanation:
The question posed relates to complex analysis, specifically the analysis of an arc represented by a complex function. The function z(t) = e⁶⁹⁴ is defined for a given interval, and the question appears to be asking for properties or values related to this function, possibly integration or differentiation. It seems the question has missing parts or typos, making it difficult to provide a complete answer without additional context or clarification.
Without the full understanding of the question, it is not possible to perform accurate calculations such as normalization, calculation of velocity or displacement, or properties of elements of the arc.
