Answer 1

Answer:

Explanation:

an iron ship floats in water because it's density is less than that of the water whereas the density of an iron nail is greater than that of water so it sinks...

As most of the space in the boat is taken up by air so it causes the overall density of boat to be lesser than that of water. Whereas, the density of the iron nail is more than that of water. Due to this the iron nail sinks while the boat floats on the surface of the water.

2.Given that,

mass=232g=232×10^-3kg

volume=20cm^3=20×10^-2m^3

Density=Mass/Volume

=232×10^-3/20×10-2

=1.26kg/m^3
