    Archimedes Principle: Pure gold or not?

    Tair=weight=mg=ρVg and 0.872Tliquid = mg-ρVg so Tair-0.872Tliquid = ρwaterVg

    Archimedes Principle: Pure gold or not?

    it should be t air - t liquid

    Archimedes Principle: Pure gold or not?

    So Tair=weight=mg=ρVg and 0.872Tliquid = mg-ρVg so Tair-0.872Tliquid = ρwaterVg

    Archimedes Principle: Pure gold or not?

    Roh=density, So Id have the density of water multipleied by the submerged volume=the density of the object times the volume of the object. The justification i have for using it is that I was able to find all the variables for it since I knew the density of pure gold was 19.3x10^3, the density of...

    Archimedes Principle: Pure gold or not?

    whoops i meant 18.36=0 not 19309.81, that number is from a differnet problem I've already completed.

    Archimedes Principle: Pure gold or not?

    Sorry about the title! originally i tried to use ROHwater(vsubmerged)=ROHobject(Vobject) but I couldn't figure out Vsubmerged so I am giving this new equation a try. I use The density of gold for ROHobject and for Vobject I calculated it by setting it equal to 0.872g/ROHobject which gave me...

    Archimedes Principle: Pure gold or not?

    Homework Statement Archimedes, prove your stuff. A royal crown (cola?) of pure gold is suspended in air by a thread and the tension in the thread is of magnitude T. When the crown is totally immersed in water, the magnitude of the tension in the thread is 0.872T. A) sketch a second law force...
