If you were able to unstrand each piece of DNA, you would see differences in time which would be labeled as "evolution"
The image formed by a concave mirror with the object placed at the center of curvature is real inverted and formed at the center of curvature. Using the ray diagram a ray from the top of the object to the mirror through f then reflected parallel to the principal axis,then the ray through the center of curvature reflected through the same point both intersect at a plane through center curvature and perpendicular to the principal axis. The point of intersection forms the top of the image and the center of curvature forms the bottom. Therefore, the correct choices are : real and inverted

Explanation:
From the question we are told that
The length of the string is 
The mass of the string is 
The tension on the string is 
The velocity of the pulse is mathematically represented as
Where 
is the linear density which is mathematically evaluated as
substituting values
Thus
The time taken is evaluated as
substituting values
