    Bouyancy - throwing rock overboard

    k in my advanced physics class 32S we are doing a project on buoyancy, one of the questions we have to answer is if you go out in a pool in a boat with a rock in it, then you throw the rock over board will the water level go up/down/stay the same. I am pretty sure that the water level will go...

    A bit of a basic question: bouyancy

    (This isn't a homework question before you ask- it just came up in something I was reading.) Am I right in thinking that a boat floating in water would float neither higher nor lower if the gravity were altered, as its mass would remain constant? Would the same remain true if an object were...

    Identifying Material Density Using Buoyancy and Volume

    A solid object floats on ethyl alcohol, with 68.2% of the object’s volume submerged. Using Table 11.1, identify the substance from which the object is made. ethyl alcohol has mass density of 806 kg/m what is the other substances mass density

    How does bouyancy work from a molecular point of view?

    Gas/liquid/solid in solid is irrelevant, liquid in gas is too dense to be bouyant, solid in liquid/gas and gas in liquid are easy. So I'm mostly interested in the liquid in liquid and gas in gas cases. Thanks.
