A uniform solid cube material 10cm on each side of mass 700g is submerged in water. which of the following best described the behavior of the cube water?
the cube will melt after a period of time
the cube will float
the cube will sink in water
the cube will rest at an equilibrium position in water
คำอธิบาย
For the uniform cube 10cm volume = 10 x 10 x 10 = 103 cm3
Mass = 700g
∴ density = (Mass)/Volume = (700)/100 = 0.7gcm-3
since the density is less than the density of water, the cube will float
Mass = 700g
∴ density = (Mass)/Volume = (700)/100 = 0.7gcm-3
since the density is less than the density of water, the cube will float
