Question

The density of ice is 917 kg/m^{3}, and the density of
sea water is 1025 kg/m^{3}. A swimming polar bear climbs
onto a piece of floating ice that has a volume of 6.83
m^{3}. What is the weight of the heaviest bear that the ice
can support without sinking completely beneath the water?

Answer #1

Volume of ice = 6.83 m^3

Mass of ice = Volume x Density = 917 x 6.83 = 6263.11 kg

Weight of ice = 6263.11 x g = 61378.478 N

Density of sea water = 1025 kg/m^3

When the bear is on top, the WHOLE ice will b submerged, meaning
the whole volume of the ice is underwater.

Buoyant force = V(d)(g) , where V is the volume of ice, d is the
density of the SEA WATER, g is the gravitational
acceleration.

Buoyant force = (6.83 )(1025)(9.8) = 68607.35 N

The weight of the bear = Buoyant force - Weight of ice = 7228.872
N

Mass of bear = Weight of bear / 9.8 = 737.64 kg

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 4.20
m3. What is the weight of the heaviest bear that the ice
can support without sinking completely beneath the water?

The density of freshwater ice is 917 kg/m^3.
Density of salt water is 1030 kg/m^3. If an ice berg has a
volume of 1000m^3, how much is below the surface?

A large tree trunk is floating in the sea. The density of the
sea water is 1065 kg/m3, the density of the trunk is 715 kg/m3.
What fraction of the trunk's volume is under the surface of the
water?

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.)

Hooded seals like the one pictured above live on drifting pack
ice. A large hooded seal with a mass of 397.8 kg climbs onto a
block of ice. Ice has a density of 916.8 kg/m3 and the density of
seawater is 1027.8 kg/m3.
1. What is the minimum size of an iceblock that will support the
weight of the seal? Answer m3
2. The seal luckily finds a large block of ice with a volume of
117.8 m3 on which...

A rectangular block of ice 13 m on each side and 1.1 m thick
floats in sea water. The density of the sea water is 1025
kg/m3. The density of ice is 917 kg/m3.
1)
How high does the top of the ice block float above the water
level?
2) How many penguins of mass 20 kg each can stand on the ice
block before they get their feet wet?

The density of water at 0°C is very nearly 1000 kg/m3
(it is actually 999.84 kg/m3), whereas the density of
ice at 0°C is 917 kg/m3. The bulk modulus of ice is 2.20
× 109 Pa. Calculate the pressure,
in pascals, necessary to keep freezing water from expanding,
neglecting the effect such a large pressure would have on the
freezing point. (This problem gives you only an indication of how
large the forces associated with freezing water might
be.)
