pliss tolong butuh banget

1. P = F/A
P = 25.000 N / 0.04 m2
P = 625.000 Pa

P 1 roda = 625.000 : 8 = 78.125 Pa

P = Tekanan (Pa)
F = Gaya (N)
A = Luas pemukaan (m2)

2. Ph = p . g . h
Ph = 1.000 . 9.8 . 100
Ph = 980.000 Pa

Ph = Tekanan Hidrostatis (Pa)
p = Massa Jenis (kg/m3)
g = Percepatan Gravitasi (m/s2)
h = Kedalaman (m)
