Answer 1

Answer:

sorry hehe

Explanation:

sorry heehee

Answer 2

Answer:

Size of object

h=2cm

Size of the object

h=?

Focal length

f=−12cm

Object distance

u=−20cm

Image distance

v=?

Using mirror formula

f1=v1+u1

−121=v1+−201

v1=60−5+3

v=−30cm

Magnification (M)

=

h

h

i

=

u

−v=−2030=−1.5

h=−1.5×2=−3cm

Image will be real, inverted and magnified.
