Question

Chapter 14, Problem 041 What fraction of the volume of an iceberg (density 917 kg/m3) would be visible if the iceberg floats in (a) the ocean (salt water, density 1024 kg/m3) and (b) in a river (fresh water, density 998 kg/m3)? (When salt water freezes to form ice, the salt is excluded. So, an iceberg could provide fresh water to a community.)

Answer #1

**ANSWERS
:**

**for visible fraction of ice (in terms of %)**

**(a) 100 - 89.55 = 10.45 %**

**(b) 100 - 91.88 = 8.12 %**

The density of ice is 917 kg/m3, and the density of sea water is
1025 kg/m3. A swimming polar bear climbs onto a piece of floating
ice that has a volume of 4.32 m3. What is the weight of the
heaviest bear that the ice can support without sinking completely
beneath the water?

The density of ice is 917 kg/m3, and the density of
sea water is 1025 kg/m3. A swimming polar bear climbs
onto a piece of floating ice that has a volume of 6.83
m3. What is the weight of the heaviest bear that the ice
can support without sinking completely beneath the water?

If your body has an average density of 989 kg/m3, what fraction
of you will be submerged when floating gently in fresh water? What
fraction of you will be submerged when floating gently in salt
water, which has a density of 1027 kg/m3?
