yeah I shouldve laid that out a little better. We covered Newtons law's, motion in general, energy, simple pressure/bouyancy, VERY basic Thermo, and basic elctrical/magnetism theory

We are to find a scientific argument and either prove it or debunk it through research. This was an introductory Physics class and he would prefer to stay somewhat within the scope of the class. Does anybody have interesting debunk-ings?

geezzzz nevermind I got it. I thought i was looking over something simple.While obtaining the forces I was neglecting my 9.8m/s^2

indeed my teach would've smacked me

The forces involved are those from bottom and those on top of object. I have drawn the diagram and I think I know the connection I'm trying to make. The volume of the displaced fluid times density has to relate to the buoyant force? I think its the Newtons that's throwing me off

A scale reads 220N when a piece of copper is hanging from it. What does the scale read when it is lowered so the copper is submerged in fresh water. From a given chart Density: copper is 8930 kg/m^3 fresh water is 1000kg/m^3 I found my volume of copper to be .0025m^3 I'm just not sure which...
