Question

calculate the density of an object of volume of 3m^3 and mass 9kg. state whether it will weigh less in water or more in water . Give reasons for ur answer

Answer 1

Answer:

Density= Mass/Volume

d= M/V

Given,

Volume= 3m^3

Mass= 9kg

Density=?

d= 9/3

d= 3 kg/m^3

Object will sink on the water surface as it's density is very less comparatively to water, water has a density of 1000 kg/m^3 at 4°C.
