Question

4. A piece of wax floats on brine. What fraction of its
volume is immersed ?
​

Answer 1

Explanation:

density of wax = 0.95g cm to the power -3

density of Brine =1.1 gram cm to the power -3

density of wax (Pw) equal 0.95 gram centimetre to the power minus 3

density of Brine (Pb) equal 1.1 gram centimetre to the power -3

let the total volume of piece of wax be v and the volume of immersed person be v

according to the law of floatation v/V = 0.95 by 1.1 = 0.86 or ,v= 0.86 V

does wax floats with 0.8 6th part of its volume above the surface brine

Answer 2

Answer:

Volume of Wax immersed = Density of wax / Density of brine

⇒

1.1

0.95

=0.86
