Question

a peice of cork has a mass of 10 kg . what is it's volume​

Answer 1

Step-by-step explanation:

Mass of cork = (10 + x ) * 0.15 g 

volume of displaced water = x 

mass of displaced water = x * 1   = x             (density of water = 1 g cm-3)

As per the Archemedes' principle 

weight of cork = weight of water displaced

x g= (1.5 + 0.15 x)g

 

x = 1.5 + 0.15 x

x = 1.5 / 0.85 = 1.765 cm3

 

total volume of the cork = 10+1.765 = 11.765 cm3

Mass of cork = 11.765 * 0.15 = 1.765 g
