The density of water is 1000 kilograms per meters cubed, and the change in distance to the surface is 2.75 meters. ... and it's equal to the weight of the water that the object displaced.

This new Goldilocks version of amorphous ice is right in the middle, almost exactly matching liquid water's density, researchers explained in a new study published in the journal Science on Feb. 2.

To find the loosely structured, Goldilocks-density ice, the team shook ordinary water ice in a jar crammed with steel balls, cooled to about -376 degrees Fahrenheit (-200 Celsius.) ...

Supercavitation projectiles potentially have 200,000 less drag than a regular object in water. April 7, 2017 August 26, 2014 by Brian Wang. Here is a summary of supercavitation an article from Caltech ...

An object in water is pulled down by its own weight and pushed up by the buoyant force exerted by the water. If the density of the boat ...

But objects in the Kuiper belt with diameters of less than 350 km all seem to be less dense than water, whereas those with diameters greater than 800 km seem to be denser than water. Density dispute ...
