An object that has a height of 0.4 meter is placed at a distance of 0.7 meter from a concave spherical mirror. an image is formed in front of the mirror and has a height of 0.35 meter. how far from the mirror is the image located?

a. 0.2000 m
b. 0.4275 m
c. 0.6125 m
d. 0.8000 m

Answer

C. 0.6125 m

Explanation

The magnification of an image produced by curved mirrors can be given in two ways;

Magnification, M = (Height of the image) / (height if the object) and

M = (image distance,V) / (Object distance, U).

Using the first formula,

M = 0.35/0.4

= 0.875

Now from the second formula,

M = V/U

0.875 = V/0.7

V = 0.875 × 0.7

= 0.6125 m

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
