Answer:
D-The information needs to travel only a short distance.
Explanation:
<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>
The first box is #3
the second box is #1
the third box is #2
the way I found this out because i read the definitions and found the key words in there.
Answer:
Explanation:
Given that,
The elevator slow to stop, this shows that it is decelerating and the final velocity is 0
v = 0m/s
Constant deceleration
a = -1m/s²
It is negative because it is deceleration
The distance the elevator descend is 4.5m
S=4.5m
Then, we want to find the time the elevator spent before stopping
Using the equation of motion
v = u + at
v² = u² + 2as
Where
v is final velocity
u Is initial velocity
a is the deceleration
s- is distance traveled
From here we can find the initial velocity of the elevator
v² = u² + 2as
0² = u² - 2 × 1 × 4.5
0 = u² - 9
u² = 9
u = √9
u = 3m/s
The initial speed is 3m/s
Then, to find the time taken, we can use the first equation
v = u + at
0 = 3 - 1 × t
0 = 3 - t
t = 3 seconds
The time taken before the elevator stop is 3 secs
