Question

Is the overall density of a Kyowa cargo ship less than one gram per cubic centimeter or more than one gram per cubic centimeter?

Answer 1

To find:

Whether overall density of a Kyowa cargo ship less than one gram per cubic centimeter or more than one gram per cubic centimeter.

Solution:

Any cargo ship (or any other passenger ship) floats on water because the amount of water displaced by it is greater than it's weight.

Hence , it experiences a buoyant force equal than it's weight for floating conditions.

This is possible , only when the overall density of that cargo ship is less than that of water.

Let density of cargo ship be $\sigma$ and that of water be $\rho$:

So, we can say:

$\therefore \: \sigma \: < \: \rho$

$= > \: \sigma \: < \: 1 \: g {cm}^{ - 3}$

So, final answer is:

$\boxed{ \bf{ \: \sigma \: < \: 1 \: g {cm}^{ - 3} }}$
