Answer 1

Jawaban:

11.

h' = 3 cm

s = 5 cm

f = 3 cm

h = ?

1/f = 1/s + 1/s'

1/3 = 1/5 + 1/s'

1/s' = 1/3 - 1/5 = 5/15 - 3/15 = 2/15

s' = 15/2 = 7,5 cm

M = s'/s = h'/h

7,5/5 = 3/h

h = 3 x 5/7,5 = 2 cm

12. B

13. B

R = 2 + 3 + 4 + 5 = 14 ohm

i = V/R = 28/14 = 2 A

V4 = i R4 = 2 x 4 = 8 volt

V5 = i R5 = 2 x 5 = 10 volt
