Some rearview mirrors produce images of cars to your rear that are smaller than they would be if the mirror were flat. Are the mirrors concave or convex? What is a mirrors radius of curvature if cars 20.8 m away appear 0.33x their normal size?

Concave mirror,-20.48m

Explanation:

Concave mirrors-This is because the objects are made smaller by the mirror, so they appear farther away.

#we find the image distance from the magnification:

#We find the focal length from:

r=2f=-10.24m*2=-20.48m

#The mirror has a negative radius(-20.48m) of curvature since its vertex  lies to the right of the center of curvature

the body's situation won't change the forces are equal opposit and on the same body

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
