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.
