12. Diketahui
P = 1000 kg/m³
g = 10 m/s²
h = 50 cm = 0,5 meter
Ditanya = Pa......?
jawab
Pa = Pxgxh
Pa = 1000x10x0,5
Pa = 5000
5000 (B)
13. 40 = 20+55
40 = 75
= 75-40
= 35
karena tarikan di sisi kanan lebih kuat maka 35 N ke arah kanan (A)
14. Diketahu
Panjang Tongkat = 6 Meter
Lb = 2 meter
Fb = 1
Lk = Total-Lb
= 6-2
= 4 meter
Ditanya= Fk.......?
Jawab
Fb/Fk = Lb/Lk
Fb.Lb = Fk.Lk
Fk = Fb.Lb/Lk
Fk = 10.2/4
Fk = 5 N (D)
