When speed slows down you have kinetic energy.
Answer:
The focal length of the lens is 34.047 cm
The power of the needed corrective lens is 2.937 diopter.
Explanation:
Distance of the object from the lens,u = 26 cm
Distance of the image from the lens ,v= -110 cm
(Image is forming on the other side of the lens)
Since ,lens of the human eye is converging lens,convex lens.
Using a lens formula:
f = 34.047 cm = 0.3404 m
Power of the lens = P

If an object's first movement is 3.0m North and another movement is 4.0m west, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.
<h3>What is displacement?</h3>
Displacement is a vector quantity. This indicates that it has both a direction and a magnitude and that it is visually represented as an arrow that points from the starting position to the ending position.
As given in the problem if an object's first movement is 3.0m North and another movement is 4.0m west
Resultant displacement can be calculated with the help of the triangle law of the vector addition,
Resultant = √( 3² + 4²)
=√25
= 5.0 m
Thus, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.
