FA = ρf. g . vb FA = 1000 kg/m3 .10 m/s2 , 1000 x 10⁻⁶ m³ FA = 1000 kg/m3 . 10 m/s2 . 1x 10⁻³ m³ FA = 10 N
Wdiair = 30 N - 10 N = 20 N
6. P = Po - h/100 x 1 cmhg di merapi : P = 76 - 2900/100 x 1cmHg = 47 cmHg di semeru : P = 76 - 3600/100 x 1cmHg = 40 cmHg
selisih = 47 - 40 = 7 cmHg
semoga membantu

Cari gaya angkat dulu
Fa=p g V
Fa=1000.10.1x10∧-3
Fa=10N
F'=F-Fa=30-10=20N
