3)A single convex spherical mirror is used to create an image of a 10.0-cm tall source that is located 35.0 cm to the left of the mirror. The magnitude of the radius of curvature for the mirror is 15.0 cm. Where does the image form?
6.2 cm to the right of the mirror
26.2 cm to the right of the mirror
35.4 cm to the right of the mirror
26.2 cm to the left of the mirror
6.2 cm to the left of the mirror
4)Two converging lenses, the first with focal length 25 cm and the second with focal length 20 cm, are separated by 30 cm. A 4.0 cm tall object is placed 50 cm in front of the first lens. Where is the final image?
20 cm after the second lens
10 cm after the second lens
50 cm after the second lens
10 cm before the second lens
20 cm before the second lens
please show all work, i will rate high
