Answer 1

Answer:

hope so it helps you dear

Answer 2

Answer:

concave lens produces a virtual, erect diminished image.

Using Real Is Positive RIP Convention, u=30 and f=-15

1/u+1/v=1/f

1/30+1/v=−1/15

1/v=−1/15−1/30=−3/30=−1/10

v=−10M=v/u=−1/3

So image is erect, virtual, 1/3 size of object, and 10 cm from the lens, (between lens and object)
