Question

a cube made of material having a density of 0.9 multiply 10 ki power 3 kg per metre cube floats between water and liquid of density 0.7 multiply 10 ki power 3 kg per metre cube​

Answer 1

Answer:

0.7×10³

Step-by-step explanation

Density of cube = 0.9×10³

Density of liquid = 0.7×10³

Thus,

Weight of body = Weight of water displaced + weight of fluid displaced

= V × 0.9×10³ ×g = 2V/3 ×10³×g+V/3pg

or, p/3 = 0.9×10³ - 0.67 ×10³

or p = 0.7×10³

Thus, the density of liquid is 0.7×10³
