Question

the volume of 60g of a substance is 20cm³. of the density of water is g 1/cm³, will the substance sink or float​

Answer 1

Answer:

Given,mass of substance,m= 50g

Volume,V=20 cm3 ; density,p =?

The density of substance given is

d=m/v= 50g/20cm3= 2.5 g cm-3

Hence,the density of substance is greater than the density of water. Hence the weight acting down wards v dg is greater than the buoyned force acting upwards vp water g

Hence the substance will sink in water
