1. Buoyancy of a pail of water problem

Ok. I got it now. Thanks a lot.
2. Buoyancy of a pail of water problem

So buoyant force will be added? I got it. How about if water spills? The spilled water will be the buoyant force that will be out of the pail. However, the object exerts a force equal but opposite of the buoyant force, so it adds weight? correct?
3. Buoyancy of a pail of water problem

So it adds weight. The weight added will be the weight of the object when in air, since buoyant force will be cancelled?
4. Buoyancy of a pail of water problem

before, the tension is the weight of the object. when submerged, the tension change since there is a bouyant force that acts on the object. Am I correct?
5. Buoyancy of a pail of water problem

Well, I think it does not add. Since the object is hung? Am I correct?
6. Buoyancy of a pail of water problem

I have a question, if a hung object is submerged in a pail of water, does the weight of the pail with water increase. The object is still hung and no water spills.

friction is normal force times the coefficient

9. Forces help

Draw free-body diagrams of each object and the forces acting on them. If two objects are connected by a single string, then they have the same tension.
10. Horsepower to kilowatt-hours?

1 kilowatt-hour = 3.6 megajoules = work power = work / time
11. What is the difference between Inertia and Interaction?

I really don't get the difference between the two. What is the difference between Inertia and Interaction? Cite examples. Homework Equations The Attempt at a Solution

Thanks.
13. Mass density of a sphere

Sorry. I interchanged 3 and 4.
14. Mass density of a sphere

let say: D = Density m = mass v = volume D1 = 1.4 kg/m3 mass is constant since the air will only be compressed. D = m/v yielding m = Dv Therefore, D1v1=D2v2 but v of sphere is (3*pi*r3)/4 and r2=r1/2 You can get it now.
