Question

Tolong kerjain no. 4 ya

Answer 1

Prinsip hukum Pascal : P1 = P2

P2 = P1 = F1/A1 = 100 N / 0.25 m2 = 400 N/m2 (c)

Answer 2

Diketahui :
F1 = 100 n
A1 = 2.500 cm2 = 0,25 m2
A1 = 2,5 m2
Ditanyakan : P2 ?

Dijawab :
F1/F2 = A1/A2
100/F2 = 0,25/2,5
F2        = (100x2,5)/0,25
F2       = 1000 N

jadi tekanan :
P2 = F2/A2
       = 1000/2,5
       = 400 N/m²
