Iron ships have large air pockets inside them making them less dense than water and thus able to float. Iron objects does not have any air pockets to make them light . If you ever heard that ships sink its because  the ship must  have  a hole in the air pocket and (air pockets are at the bottom layer of ships) water fills through the air pocket and adds weight making it sink.


Hope this helps :)

American football uses a field that is 100.0yd long, whereas the a soccer field is 100.0m long. Which field is longer and by how
ioda
I'm using    1m = 3.28084 ft

1 yd = 3 ft

100 yd = 300 ft
100 m = 328.084 ft   the soccer field is longer
                                    by 28.084 ft
                                    =   9.36 yards
                                    =   8.56 meters    

The percentage of  100m  compared to  100 yd  is the same as
the percentage of  1m  compared to  1yd .

           1m / 1yd  =  3.28084 ft / 3 ft

                            =  1.0936

            The soccer field is  9.36%  longer.

Why does the Polaris appear to remain stationary in the night sky when other stars show an apparent pattern?
yanalaym [24]
Because one pole of the Earth's axis of rotation (the North one) points
almost exactly toward Polaris.

If Polaris had a pimple or a bump somewhere on its edge, you'd see
the bump rotate around the whole edge, like a clock, once a day.  But
the whole star appears to stay in one place, because our axis points to it.
