Answer:
- the iron + boat system displaces more volume than the iron alone
- the system is the iron alone, it displaces the same volume in the boat and the water
Explanation:
The Archimedes principle states that the thrust is equal to the weight of the dislodged liquid.
B = ρ g V
Let us analyze this case the weight of the iron is the same either in the boat or at the bottom of the sea, but the volume that moves from water is greater when it is in the boat, it is already the area of the boat that moves the water, whereby the iron and the boat does not sink.
When the iron is on the surface of the water in displaced volume it is in the iron (V_Iron << V_boat), so in the relation
B- W = m a
The weight of the iron is greater than the thrust and it sinks
two posibilities
Therefore, the iron + boat system displaces more volume than the iron alone
If the system is the iron alone, it displaces the same volume in the boat and the water
The boat-iron system will displace more water than that of the iron trace alone.
What is Archimedes' principle?
It states that the upward buoyant force exerted on a body immersed fully or partially in a fluid is equal to the weight of the fluid displaced by the body.
[tex]B = \rho g V[/tex]
Where,
B - buoyant force
ρ - density of the fluid
g - gravity
V - the volume of fluid displaced
Since the boat-iron system has more volume,
Therefore, the boat-iron system will displace more water than that of the iron trace alone.
