Question

Bantu jawab no 3 sama caranya ya.. terima kasih :-)

Answer 1

Diketahui :
h = 9 cm
s = 15 cm
f = -10 cm

ditanyakan :
s' = ?
M = ?
h' = ?

jawab :
1/f = 1/s + 1/s'
-1/10 = 1/15 + 1/s'
1/s' = -1/10 - 1/15 = -3/30 - 2/30 = -5/30
s' = -6 cm

M = s'/s = 6/15 = 0,4 kali

h' = M x h
h' = 0,4 x 9 = 3,6 cm
