1.

volume of an object is 20cm3 and the mass in 50gdensity of water is 1gcm -3 will the object float on water or sink in water

Answer» DENSITY of WATER = 1g/cm^3

VOLUME = 20cm^3

mass = 50g

density = mass / volume

= 50 / 20

= 2.5g/cm^3


Because density of object is more than that of water. So it will sink.



Thanks
