Question

Tolong jawab yaa nomor 1 dan 2 nyaa yg bener

Answer 1

Verified answer

Nomor 1
ρ = 1 gr/cm³ = 1000 kg/m³
g = 10 m/s²
h = 200 cm - 80 cm = 120 cm = 1,2 m
Ph?

penyelesaian:
Ph = ρ . g . h

Ph = 1000 . 10 , 1,2

Ph = 12.000 Pa

nomor 2
m = 400 gr = 0,4 kg
g = 10 m/s²
A = 20 cm² = 0,002 m²
P?

penyelesaian:
P = F / A

P = m . g / A

P = 0,4 . 10 / 0,002

P = 4 / 0,002

P = 2000 N/m²

Answer 2

Verified answer

1.Dik;
p=1 gram/cm³=1000 kg/cm³
g=10m/s²
h=200-80cm=120 cm=1,2

Ph=_________?
penye:
Ph=P.g.h
Ph=1000×10×1,2
Ph=12000pa

2.Dik:
m=400 gram=0,4 kg
g=10m/s²
A=20cm²

P=_________?
penye:
P=F/A
1)cari F nya dulu
F=m.a
F=0,4×10
F=4 N
2)cari P nya
P=F/A
P=4/20
P=0,2 N/cm²

semoga membantu:3
semangat ya belajar nya:3
