Based on Archimedes' principle, we know that if an object displaces a given weight of water, then the object is being buoyed up by an equal amount of force.
2 answers:
True. If the amount displaced is more than the mass, it floats. If the amount is less than the mass, it will sink.
Answer:
The answer is True.
Explanation:
According to the Archimedes' principle , the buoyant force is equal to the submerged volume multiplied by the density of the displaced liquid ; This happens because when the body is submerged , the fluid will exert an equal and opposite direction force , due to the change in pressure.

Answer:
Wc = 7.84 weight of crown
Ww = 7.84 - 6.86 = .98 weight of water displaced
Density = 7.84 / .98 = 8 crown is 8 X that of water
Since gold has a density of 19.3 that of water the crown is certainly not 100 percent (if any) gold
Yes, the friction is acting in the opposite direction you are pushing.
I know that E.) Tension Force is one of them and B.) Gravity Force but I'm not sure about the others.
