Sebuah balok terapung diatas permukaan air. volume balok yg muncul diatas permukaan air 100 cm³ dan massa jenis balok 0,75g/cm³ jika p air 1 g/cm³ hitunglah massa balok seluruhnya...???

Dik vb=vc = 100 cm^3 Rho balok = 0,75 g/cm^3 rho cair = 1 g/cm^3 dit m balok seluruhnya ? jawab.
Fa = rho cair.volume cair . g = 1 . 100. 10 = 1000 N
Fa = wb = mb . g mb2 = rho benda . v 1000 = mb . 10 = 0,75 . 100 mb1 = 1000 / 10 = 75 gr = 100 gr
Rho balok = 0,75 g/cm^3
rho cair = 1 g/cm^3
dit m balok seluruhnya ?
jawab.
Fa = rho cair.volume cair . g
= 1 . 100. 10
= 1000 N
Fa = wb = mb . g mb2 = rho benda . v
1000 = mb . 10 = 0,75 . 100
mb1 = 1000 / 10 = 75 gr
= 100 gr
m total = 100 + 75 = 175 gr
