ρ kayu = 700kg/m3
ρ air = 1g/cm3 = 1000kg/cm3
ρair > ρkayu
massa jenis air lebih besar dari pada kayu sehingga seluruh bagian balok tampak diatas permukaan air (a.)
5.
ρ raksa = 13,500kg/m3
g= 10m/s2
h = 0,76cm->0,0076
P,?
P = ρ.g.h
P = 13500.10.0,0076
P =13,5x10⁴. 76x10⁻⁴
P = 1026 Pa -> 10³ Pa
6. M logam = 5200mg -> 5,2g
V = Vakhir - Vawal = 60-50 = 10cm3
ditanya massa jenis ρ?
ρ = m/v
ρ = 5,2 / 10
ρ = 0,52 g/cm³
