Dear Student ,
20(a)
20(b) The mirrors used in cars are convex mirrors. Convex mirrors form erect and smaller images of the objects. This does not give us the exact idea how far the vehicle is from us. Thus, to avoid accidents, car view mirrors carry a warning message that objects in the rear view mirror are closer than they appear.
Kindly post different query in separate threads
Regards
