Answer 1

Answer:

h = 6cm , u = -18 cm , v = - 12 cm

1/v + 1/u = 1/f

1/f = 1/-12 + 1/-18

1/f = 1/-12 - 1/18

1/f = - 3 - 2/36

1/f = -5 /36

f = 36/-5

f = -7.2 cm

2) R = 2f

R = 2(-7.2)

R = - 14.4 cm

3) m = -v/u

m = -(-12)/-18

m = 12/-18

m = 2/-3

m = 0.6

4) hi /h = -v/u

hi = -v (h) / u

hi = -(-12) (6) /-18

hi = 72/-18

hi = -4 cm
