Which of the following represents an upside-down image? o a. +doo b. -doo c. +mo d.-m

D. -m

Explanation:

The magnification of an image is equal to the following ratio:

where

y' is the size of the image

y is the size of the real object

We have two situations:

- When m is positive, it means that y' has the same sign of y --> so the image has same orientation of the object (= image is upright)

- When m is negative, it means that y' has opposite sign to y --> so the image has opposite orientation to the object (= image is upside down)

So, the correct answer that describes an upside-down image is

D. -m

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
