Herro!
Simon Tao here to help again!
So, the upward push of water creates this power force otherwise known in physics terms as can also be described by intuitive concepts such as a push or pull thus determining the y axis. By allowing people to work out the volume of x, it provides the reader with a great intensive to dislocate a gradient.
Hope this helped! :)
Thank you,

Rubber ducks float because:They are made from a lightweight substance meaning upthrust from the water can counter-balance the downward force from the duck's weight.Their bottom has a large flat surface area, meaning the upthrust has a larger area to push against.They are filled with air, which is lighter and less dense than water, so it will naturally push upwards in water (think of when you blow bubbles underwater-the bubbles float upwards)Hope I helped :)
because the upthrust force of the water acting on the stone was pushing the stone upwards meaning it was acting against the downwards weight of the stone (its weight). This meant that the downwards force was decreased and therefore felt lighter :)
Because both salt and sugar are polar (though salt more so) neither will float, but rather both will dissolve in the water. But, assuming that both were not soluble in water, again, neither would float because both are more dense than water is.
