Properties Of Solids And Liquids Question 254
Question: An iceberg is floating partially immersed in sea water. The density of sea water is $ 1.03gc{{m}^{-3}} $ and that of ice is$ 0.92gc{{m}^{-3}} $ . The approximate percentage of total volume of iceberg above the level of sea water is
Options:
A) 8
B) 11
C) 34
D) 89
Show Answer
Answer:
Correct Answer: B
Solution:
[b] $ (V-\Delta V)\times 1.03\times g=V\times 0.92\times g $
Or $ \frac{V-\Delta V}{V}=\frac{0.92}{1.03} $
Or $ \frac{\Delta V}{V}=1-\frac{0.92}{1.03}=\frac{0.11}{1.03} $
Or $ \frac{\Delta V}{V}\times 100=\frac{11}{1.03}\approx 11 $
