Benda homogen mengapung di atas air (massa jenis air 1 g/cm) dan 3/10 bagian benda berada di bwh permukaan air, massa jenis benda adalah...
Remoraa
Diketahui = p = 1 g/cm³ ⇒ 1000 kg/m³ V = 10/10 - 3/10 = 7/10 Ditanya = p benda Jawab pgV = pgV 1000 x 7/10 = p x 3/10 700 = p x 3/10 p = 3/10 x 700 p = 30 kg/m³
V = 10/10 - 3/10 = 7/10
Ditanya = p benda
Jawab
pgV = pgV
1000 x 7/10 = p x 3/10
700 = p x 3/10
p = 3/10 x 700
p = 30 kg/m³
