Convert the following a) The density of ice is 920 in kgm-3 (SI to CGS system)​

Answer»

Answer:

Correct option is

A

0.107

Let V

L

and V

S

be the volume of WATER displaced and volume of the ice respectively; ρ

L

and ρ

S

be the density of water and density of ice respectively. Since ice is floating on water, F

B

=W

or ρ

L

V

L

g=ρ

S

V

S

g or ρ

=ρ

S

This is the FRACTION of volume of the iceberg that is inside the water. THEREFORE, the fraction of volume of the iceberg that is outside the water is GIVEN by, 1 - 0.893 = 0.107

Hence, the fraction of the total volume of an iceberg is outside the water is 0.107.
