Verified answer
g = 9,8 m/s²
rho = 0,8 g/cm³ = 800 kg/m³
wu = 5N
wa = 3,4 N
Ketika di dalam suatu fluida Gaya Archimedes 'mengurangi' berat benda di udara
Fa = wu - wa
rho * g * vb = 5 - 3,4
800 * 9,8 * vb = 1,6
vb = 4.900
wu = m * g
5 = m * 9,8
m = 5 / 9,8
Massa jenis benda = massa / volume
= (5/9,8) : 4.900
= 0,0001 kg/m³
= 0,1 g/cm³ ✔️
Semoga jelas dan membantu
