jawab dengan benar pake cara besok dikumpulkan aku butuh ahli fisika atau ahli branly yg menjawab

nomor 11
rho = 1000 kg/m^3
g = 10 m/s^2
h = 5 m - 1 m = 4 m
Ph?

penyelesaian:
Ph = rho × g × h

Ph = 1000 × 10 × 4

Ph = 40.000 Pa

nomor 12
rho = 1000 kg/m^3
g = 10 m/s^2
hx = 50 - 20 = 30 cm = 0,3 m
hy = 50 - 30 = 20 cm = 0,2 m
Phx?
Phy?

penyelesaian:
A.) Phx?
Phx = rho × g × hx

Phx = 1000 × 10 × 0,3

Phx = 3000 Pa

B.) Phy?
Phy = rho × g × hy

Phy = 1000 × 10 × 0,2

Phy = 2000 Pa

maka perbandingannya:
Phx : Phy

3000 : 2000

3 : 2
