1) My teacher says that the apparent weight of an object in water (floating,sunken,submerged etc) is equal to it's actual weight-buoyant force acting on it.
That is, wt (ap)=wt (ac)- F(b)
Where wt (ap) = apparent weight,
weight (ac)= actual weight.
And f (b) = buoyant force
2) But..., if an...
What i interpret from this;my understanding of buoyant force (please correct me if I'm wrong. )
Take for example the sea
The water below will provide some force to support the weight of the water above it. When some object is put in water ( for this case, let's consider it is denser than...
