Answer 1

3. P = F/A = 80x10/0,4x10 = 800/4 = 200 N/m2 4. Tidak di tau 6. 1/s + 1/s' = 1/f 1/10 + 1/s' = 1/15 1/s' = 1/10 - 1/15 1/s' = 3/30 - 2/30 1/s' = 1/30 1xs' = 1x30(perkalian silang) s' = 30 cm M = |s'/s| = |30cm/10cm| = 3 cm 5. 1/s + 1/s' = 1/f 1/8 + 1/s' = 1/6 1/s' = 1/8 - 1/6 1/s' = 3/24 - 4/24 1/s' = -1/24 -1xs' = 1x24 -s' = 24 s' = 24/-1 s' = -24 cm
