Tolong bantu jawab ya

jawabannya B.0,80 semoga terbantu

FLUIDA
• Hk Archimedes

b = balok, c = zat cair
Vt = (ρb/ρc) Vb
(4/5) Vb = (ρb/ρc) Vb
4/5 = ρb / ρc
ρb = 4/5 ρc
ρb = 0,8 ρc ← jwb



catatan:
penurunannya
pada keadaan setimbang
ΣF = 0
F - w = 0
F = w
ρc g Vt = mb g
ρc g Vt = (ρb Vb) g
ρc Vt = ρb Vb
Vt = (ρb/ρc) Vb
