<span>There is an low cost and quickest alternative available for adaptive optics. Name of this technique is wavefront coding. The numerical analysis pretends to show the robustness of the technique under changes in pupil diameter and wavefront shape including intersubject and intrasubject variability, using always the same restoration filter or image decoder .Using this technique it is possible to obtain high resolution images under different ocular aberrations and pupil diameters with the same decoder, opening the possibility of real time high resolution images.</span>
Answer:
The velocity is 
Explanation:
From the question we are told that
The diameter of the pipe is 
The magnetic field is 
The hall voltage is 
Generally the average fluid velocity is mathematically represented as

=> 
=> 
A because its about an opening in the sea floor and tectonic plates are the only thing.
Answer:
Efficiency of this process is 30 %.
Explanation:
It is given that,
Electric energy used by the machine, 
The potential energy of the machine is increased,
The efficiency of this machine is given by :


So, the efficiency of this process is 30 %. Hence, this is the required solution.
The amount of current flowing through the wire
The number of coils in the wire
The material in the core
