When the weight of an object equals the weight of the water displaced (or pushed away) by the object, the
object is neutrally buoyant and easy to lift to the surface.
A sailboat sank to the bottom of the ocean. The majority of the boat's weight is from the 0.25 m² of lead
in its keel. The density of lead is approximately 11, 000 kg/m”. The density of seawater is approximately,
1000 kg/m'. Because gravity is pretty much the same everywhere on Earth, the weight of the sailboat
can be assumed to be approximately equal to its mass.
In cubic meters, what is the total volume of seawater needing to be displaced in order to lift the sailboat
to the surface?

none.

what is the missing angle?

the forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?

answer: 3 times more

step-by-step explanation: so the polar bear weighs 3 times more   than the black bear. so the grizzly weighs twice as much as the black bear. a good hint for word problems is to draw the problem out
