Answer:
u = - 20 cm
m =
Given:
Radius of curvature, R = 10 cm
image distance, v = 4 cm
Solution:
Focal length of the convex mirror, f:
f = 
Using Lens' maker formula:

Substitute the given values in the above formula:


u = - 20 cm
where
u = object distance
Now, magnification is the ratio of image distance to the object distance:
magnification, m =
magnification, m =
m =
m =
Answer: the answer should be 6,720 decameters.
Answer:
I think it's (C) magnitude and direction
Explanation:
scalar is only magnitude and no direction so that answer makes no since, and i would think speed can't go anywhere without direction so i think (C)
hope it's right
