<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:
23.49m
Explanation:
Distance = velocity x time
8.7 x 2.7 = 23.49m
The fact that large elliptical galaxies are more common in central galaxy clusters suggests that collisions play a role in the formation of these galaxies.
<h3>What is galaxy formation?</h3>
Galaxy formation is a physical phenomenon where molecular clouds of dust concentrate and thus first generate stars.
Galaxy formation is a process that can be associated with collisions, at least for the formation of elliptical galaxies.
Collisions are a relatively frequent process in clusters (groups) of galaxies that are formed by crashes with other galaxies.

For the orbital speed of a spacecraft we know that
here
M = mass of the planet around which satellite is revolving
r = orbital radius
Now when thruster is used by the spacecraft its speed will change due to which orbital speed will change.
Since here while changing the speed mass of the planet will be same
we can say the speed of the spacecraft will changed by thruster due to which its orbital radius will change
so the correct answer must be
<em>b. the spacecraft will change motion and will maintain this new orbit until the thruster is fired again.</em>
