P...?
Luas alas = panjang x lebar = 5 x 2 = 10m²
F = 1000N
Tekanan = F/A
P = F/A
P = 1000/10
P = 100Pa
Jawabannya adalah A. 100pa.
No. 34
Diketahui :
P1 = 2atm
V1 = 4m³
P2 = 0.5 atm
Ditanya : V2..?
Jawab :
P1 x V1 = P2 x V2
2 x 4 = 0.5 x V2
8 = 0.5 x V2
V2 = 8/0.5
V2 = 16m²
Jawabannya adalah A. 16m³
No. 35
Diketahui :
Pu = 76cmHg
Ph = 54cmHg
Ditanya : h..?
Jawab:
h = (Pu - Ph) x 100
h = (76 - 54) x 100
h = 22 x 100
h = 2200 meter.
Jawabannya adalah D. 2200m.
