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?
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?
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.
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.
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
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.
