Answer:
just-noticeable difference
Explanation:
Using principles of psychology and physics, a branch of experimental psychology called psychophysics has been created. This field is focused on the sensation, the sense and the perception of stimuli. Within this branch it has been called just-noticeable difference to the amount that must be changed of some stimulus so that this difference is noticeable, that is to say, the threshold at which the change is perceived.
<span>The correct answer for this question is this one:
"The wing tip is moving around a circle at a constant speed. And it says that the acceleration is centripetal. It moves a distance that is equal to the circumference of a circle, as </span>the wing makes a complete circle<span>. The radius of the circle is equal to one half of the wingspan.
</span>Circumference = 2 * π * 6.6 = π * 13.2
<span>To determine the velocity, divide this distance by 22 seconds. </span>
<span>v = π * 13.2 ÷ 22 </span>
<span>This is approximately 1.885 m/s. </span>
<span>Centripetal acceleration = (π * 13.2 ÷ 22)^2 ÷ 6.6 </span>
A recurring illness. Typically lasts for a very long time and are very hard to remove.
If you mean 6.9 miles the it is 11.1045 kilometers. You can round it to the tenth place to get 11.1
